Seekins Precision produces a wide variety of expertly-machined products such as scope rings, picatinny rails, and sling rails. Seekins products are priced competitively, but give up nothing in quality to some more expensive brands.
At SHOT 2009, Glen Seekins unveiled some cool, new products, including a new AR15 lower with many unique features. The Seekins SP223 lower features flutes on the magwell front face for improved grip, plus an enlarged triggerguard allowing use with gloves. The new lower takes standard milspec mags as well as MagPul P-Mags. It should be available in April 2009, with a price of about $350. Glen tells us that a Seekins AR upper design will follow “down the road.”
Seekins also announced new Remington 700 bottom metal. The Seekins R700 bottom metal assembly is made from 7075-T6 Aluminum allow — very tough stuff. The R700 is currently offered for .223 Rem, .308 (and other standard short action rounds), and .338 Lapua. A WSM version will be available soon. This bottom metal works with 5-round magazines, but Seekins will be offering 10-round .223 and .308 mags in the summer.
In October, we published a preliminary report on the new 30 Remington AR cartridge, complete with diagrams and factory load specs.
At SHOT 2009, Remington displayed Remington 30AR rifles and factory-loaded ammo. There were no great surprises. This is a short, fat cartridge (.308 bolt-face) that holds about 44 grains of H20. Case size and capacity were pretty much dictated by AR15 magazine dimensions: “According to Outdoor Life columnist John Snow: “DPMS President Randy Luth and Remington’s John Fink (brand manager for the rifle division) … both said that the goal was to look at the AR lower and see how much cartridge they could fit in there.” The Rem 30AR uses a single-stack magazine holding four (4) rounds.
Factory Rem 30AR ammo is loaded with 125gr projectiles running about 2800 fps. While the 0.267 BC for those bullets is pretty low, the cartridge should perform its intended job of harvesting deer just fine. Jason also believes that, if the Remington-brand brass is decent, this cartridge could have real potential in Hunter Benchrest and for subsonic work.
Some months ago, AccurateShooter.com and Robert Whitley teamed up to build a new 20-caliber AR15-based rifle. Our project goal was to create the “ultimate” semi-automatic prairie dog rifle. We wanted a low-recoiling, flat-shooting AR that worked great with a front rest and rear sandbag on a transportable field bench (such as the Coyote Jakes bench). We knew the basic AR15 design needed some “upgrades”, so Robert developed Delrin bag-riders for the forearm and buttstock. But we wanted the bag-riding components to be removable so the gun could be easily returned to standard configuration for shooting with sling or bipod. Robert worked with EGW to develop machined Delrin bag-riding units front and rear. The 3″-wide front “sled” attaches to the threaded anchor for the sling swivel stud, while the rear bag-rider mounts in place of the standard rear sling loop.
Our Ultimate Prairie Dog Rifle (PDR) features a 24″ Bartlein 11-twist cut-rifled barrel, DPMS side-charging upper, and a Jewell trigger. It is chambered in “20 Practical”, a cartridge popularized by Warren “Fireball” Brookman. This is simply the .223 Remington necked down to .204. You can use your existing .223 brass — no special case-forming required! The 20 Practical is accurate, flat-shooting, and has almost no recoil. The advantage over the standard .223 Remington is that, grain for grain, the bullets have a higher BC and travel at a higher velocity for more dramatic effect on a small varmint. The ultra-low recoil allows you to easily see your hits, even without a muzzle brake. The 20 Practical, launching 40-grainers at about 3750 fps, shoots flatter than a .223 Rem with 55gr hollowpoints.
Robert has lots of experience building AR15 uppers and he has developed advanced features that make the gun much more ergonomic and easier to shoot from a prone position or from the bench. First, Robert offers a side charging handle. This lets you keep your head in shooting position while charging the gun or retracting the bolt. Second, he has fitted a GG&G extended scope rail. This permits the scope to be mounted far enough forward to allow proper eye relief while using a high-magnification scope. Without an extended scope rail you typically have to move way back on the gun to get enough eye relief and then you can’t seat the buttpad properly on your shoulder.
In the video above, Robert shoots the Ultimate PDR with Berger 40gr BTHP bullets. Robert is using the Caldwell Fire Control front rest and rear sandbag. The Fire Control Rest is an affordable, joystick-style mechanical rest that allows you to easily adjust windage and elevation with a single movement of the joystick. The rest is solid and sturdy; Robert says it worked well.
In this session, Robert shot three five-shot groups. Each group could be covered by a dime, which measures 0.705″ in diameter. Subtract the 0.204″ bullet diameter, and you can see this rifle easily shoots under half-MOA, even rapid fire (groups 1 & 2). For the third (and last group), Robert slowed down the pace, aimed more precisely, and put five shots in 0.257″. Not bad for shooting off a wooden bench without wind flags! Like what you see? As soon as accuracy testing is complete, this rifle will be auctioned off to benefit this website. EGW will be offering the front and rear Delrin bag-riders. They will cost $40 each or both front and rear for $75.00 total. Robert will also be offering 20 Practical uppers for your AR15.

Remington Arms just introduced a new cartridge, the 30 Remington AR (aka “30 RAR”), to be used in AR-platform rifles to be built by its DPMS subsidiary. (Remington, DPMS, and Bushmaster are all owned by Cerberus Capital Management, a private holding company.) The cartridge carries the “short, fat” design to the extreme. It is based on a shortened version of the .450 Bushmaster, which itself was a cut-down version of the .284 Winchester. Like the .284 Win, the 30 Remington AR has a rebated rim, so it will fit a .308 Win-sized boltface (0.473″). While it resembles a 30BR, the new case is much fatter, offering an impressive 44 grains of powder capacity. The portly diameter of the 30 RAR case dictates that the magazine will be a single-stack, and will hold only four (4) rounds.
Cram a Big Cartridge in an AR15 Mag and Make Sure It’s a Thirty
What was Remington thinking? Well, the stated project goal was to transform the standard AR15 into a “legitimate big game hunting platform.” Presumably, a 30-caliber cartridge was chosen for marketing purposes as that is the most common deer hunting caliber. The “science” of the design was basically to stuff the biggest cartridge possible in a standard AR15-sized magazine. According to Outdoor Life columnist John Snow: “DPMS President Randy Luth and Remington’s John Fink (brand manager for the rifle division) … both said that the goal was to look at the AR lower and see how much cartridge they could fit in there.”

Factory 30 Remington AR Rifles and Uppers
Initially, the 30 Remington AR round will be chambered in complete, DPMS-built Remington R15 rifles, which start at $1,199.00 MSRP. For production rifles, the expected rate of twist is 1:10″, but that has not been finalized. What about separate uppers? Given the hefty price of the complete rifle, existing AR owners may prefer to purchase a 30-caliber upper by itself. While no release date was given, Remington stated that 30 RAR uppers will definitely be offered for sale in the future.
Impressive Velocities but Much Less Energy than a .308 Win Shooting 160s
With 44 grains of capacity, the 30 RAR can generate some impressive velocities with bullets in the 120-125gr weight range. Remington claims its 125gr factory ammo will deliver 2800 fps muzzle velocities running at about 55,000 psi pressure levels. Three factory loads will be offered: Rem-branded 125gr Core-Lokt PSP and 125gr AccuTip BT, and a UMC-branded 123gr FMJ. At $18.99 per 20-round box, the UMC ammo is intended for inexpensive practice purposes. The $35.99/box AccuTip and $26.49/box Core-Lokt PSP are much costlier. The relatively light-weight bullets used in the Remington ammo have poor Ballistic Coefficients compared to the longer, heavier bullets typically used in a .308 Win or 7mm-08. The 125gr Core-Lokt has a 0.267 BC, while the 125gr AccuTip is somewhat better at 0.335. Nonetheless, Remington’s ballistics tables show that the AccuTip should match the trajectory of a 165gr AccuTip (fired from a .308 Win), fairly well out to 400 yards. However, there is a BIG difference in energy as you can see from the table below. At 300 yards, the 125gr AccuTip delivers 1153 ft/lbs of energy compared to 1661 ft/lbs for a 165gr AccuTip launched at 2700 fps from a .308 Win. (Note: these numbers were calculated with 24″ barrels. Remington’s 30 RAR-chambered R15 rifle has a 22″ barrel, so its performance should be somewhat less impressive.)
COMMENTARY by EDITOR
Our first reaction to the news of Remington’s new cartridge was: “Why?” The obvious (and cynical) answer is that Remington wanted to sell AR-style rifles to deer hunters who need an excuse to purchase a military-style semi-automatic. There may be a market for that… who knows. But there is already a proven, compact 30-caliber cartridge that fits a standard-sized AR15 lower — the 7.62×39. The 7.62×39 won’t push a 125-grainer as fast as the bigger 30 RAR, but the 7.62×39 will still kill a whitetail plenty dead. Perhaps Remington’s engineers should simply have applied themselves to producing a proper (i.e. 100% functional) 7.62×39 magazine. This Editor has tried most of the AR15 7.62×39 magazines on the market (from 3-rd to 30-rd capacity). None of those I tested worked particularly well. Some simple redesign work (call the MagPul folks) would solve that.
Better AR Ballistics with 6.5 and 6mm Cartridges
If the goal was to produce an AR15 with better ballistics and downrange energy than the .223 Rem cartridge delivers, we’re not sure a 30-caliber was the way to go. The 6.5 Grendel performs exceptionally well in AR rifles, delivering great accuracy with 123gr Lapua Scenar or Sierra bullets. Likewise, the AR15 can be a superb High Power and Cross-the-Course platform shooting the 6mmAR cartridge developed by Robert Whitley. The 6mmAR is the 6.5 Grendel necked down to 6mm. Shooting 105 Berger VLDs it comes very, very close to the ballistics of the larger 6mmBR cartridge, and it gives up nothing in accuracy. By contrast, with its low-BC bullets, the 30 Remington AR is not going to be competitive at longer ranges with either the 6.5 Grendel or the 6mmAR. And with factory mags limited to four (4) rounds, you couldn’t use this gun effectively in High Power matches, even if it proves highly accurate on the short course.
Important Innovation or Another Orphan Cartridge?
Only time will tell whether the 30 Remington AR cartridge will catch on with sport shooters and hunters. We’re not sure the round has an important purpose that cannot be filled by existing, proven cartridges. The complete 30 RAR rifles are expensive ($1200+) compared to a typical bolt-action deer rifle, so we wonder how many deer hunters will actually jump on Remington’s bandwagon. Speaking frankly, so long as the cartridge is available only with Remington-made brass, we predict little interest among competitive shooters. Now if Lapua were to produce a 65,000-psi rated version of this cartridge, THAT might interest hunter benchrest shooters and BR for score shooters. A Lapua 30 RAR would be like a 30BR on steroids. But alas, don’t expect Lapua, or Norma, or even Winchester, to produce 30 RAR brass any time soon.
So, does the 30 Remington AR (aka “30 RAR”) have a future? It will certainly stimulate sales of AR-platform rifles to some extent. That’s important because AR sales have been lagging recently. Perhaps that is enough justification for a new round. All things considered however, we think Remington would have been better off building its “AR for big game” around the 6.5 Grendel case, perhaps in a 7mm version. Still, we have to credit Remington’s designers. Using a modern “short, fat” design, with a rebated rim, they’ve achieved impressive velocities in a very compact cartridge. The chopped-down .284 may prove to be a very accurate design.
Site Contributor Danny Reever has tested the bargain-priced PRVI Partizan .223 factory ammo in his 7-twist Sig 556 and AR15. He gives it a definite “thumbs-up”. Danny reports: “You should try some of the Prvi Partizan 75gr Match ammo. I was really surprised. This stuff shoots great. At 100 yards it delivered one MOA, easy, with my Sig 556. With a custom match rifle it might do even better. This is great ammo for the price, with quality brass, all boxer-primed and reloadable.”
200 rounds for $85.00 at Wideners Wideners.com recently received large supplies of the Prvi Partizan 75gr .223 Match ammo. “This ammo is just off the boat! Brand new 2008 production that we received last week after clearing US Customs on July 2nd.” Price is $85.00 for 200 rounds (10 x 20-ct boxes), or $419.00 for 1000 rounds. The 1000-round price works out to $8.38 per 20 rounds.
Other companies have the same ammo, but it is priced higher right now. Aim Surplus has the ammo at $89.50/200 rounds, while Grafs.com is selling it for $10.99/box (shipping included, item PPA223MATCH).
Stan Widener tested the ammo and reports: “After firing, the brass was very clean and there was very little residue on the bolt carrier. Very clean powder. The ammo is made with MILAN BLAGOJEVIC powder and GINEX primers. There were no failures or misfeeds of any kind. All rounds functioned perfectly. The cases are very bright and shiny with military anneal mark.” An 8-twist or faster barrel is recommended for this 75gr Prvi Partizan ammo.
AccurateShooter.com has teamed with Robert Whitley and Carl Bernosky to develop a new AR15-based, 20-caliber rifle optimized for varminting. The chambering is a 20-223 with a PT&G (Kiff) reamer, aka the “20 Practical”, a name coined by Warren Brookman*. The cartridge uses standard .223 Remington brass. Case forming is simple — just neck down the brass (Robert did this in two steps, with .233″ and .225″ bushings). You do NOT have to move the shoulder back as with the 20 Tactical. You can even use your existing .223 Rem Redding dies by swapping out some internal components.
While Carl is still working on special (top-secret) “furniture” to help the 20 Practical AR ride the bags, Robert was able to test the first complete 20 Practical AR upper built with a Bartlein barrel. Without any special load development, the gun has proved very accurate, putting 5 rapid-fire shots in a dime-sized group at 100 yards. Robert was using H335 with 40gr bullets. This load runs 3750 fps and Robert thinks more velocity may be possible with H335. We will also test other load recipes for both both 40gr and 32gr bullets. H322 should also be a good choice for both bullet weights. Quickload predicts H322 will send the 32-grainers past 4000 fps, and Warren Brookman says: “For both 32gr and 40gr bullets, Vihtavuori N133 is just about the perfect powder for the 20 Practical. It burns clean, delivers great accuracy and good velocity.”
Robert reports: “I loaded up some new brass today (Winchester brass, factory primed). I only used H335 and the Berger 40 gr BTHP bullets at about .010″ off the lands (2.228″ OAL). The thing is very accurate. First group shot off the bench after sight-in is shown in the video. Keep in mind this was done with no load work-up and I shot fast to ensure the video was not too long. The load was with 26.0 grains of H335 and the Berger 40-grainers going right around 3750 fps.”
If you shoot a .223 Rem currently it’s easy to load for the 20 Practical. You will need a Redding Type ‘S’ neck-bushing full-length sizing die, and Robert recommends a Redding Comp Seater. Then you’ll need some extra bits of kit:
1. Powder funnel that fits .20-Cal case mouths
2. Two neck bushings: .233″ and .225″
3. 20-Caliber cleaning rod with brushes, jag, patches, etc.
4. Decapping rod assembly for 20 Cal (a 204 Ruger one works perfectly — about $15)
*The 20 Practical chambering, a modern 20-223 Wildcat, was popularized by Warren Brookman, whose 20 Practical bolt gun was featured as our 61st Gun of the Week. In that 20 Practical Article, Warren explains the thinking behind the cartridge and shows how to adapt .223 Rem Redding dies.

PRVI Partizan 75gr Match ON SALE for $8.99/box
Now through May 31, 2008, MidwayUSA has the PRVI 75gr Match Ammo on sale (ITEM 790565). This is the same stuff that worked so well for Danny. The sale price is just $8.99 per 20-rd box, marked down from $11.99. You may want to jump on this deal before the price goes back up June 1st. (NOTE: 1:7″ or faster twist required.) Midway customers who have tried this ammo agree with Danny — this is quality 1 MOA or better ammo:
In my RRA Predator Pursuit rifle this ammo produces consistent 1 inch groups at 100 yards. Burns clean with no funky powder odors, no feed problems were encountered. Brass is clean and shiny, good practice and hunting round. Get it now before the price goes up. — Juan S., TX
Comparable to MUCH more expensive ammo in both accuracy, and terminal performance. EASILY shoots sub-MOA groups @ 200 yards from my RRA A4 Varmint. Stock up while you can! — Paul J., AL
I shot this ammo out of my Colt H-Bar AR 1-7 twist and got 1″, 5-shot groups at 100 yards. I doubt you’ll do better than that for this price. I will be ordering more. — David A., AL
Wideners has PRVI Partizan 75gr .223 Bulk Packs Wideners.com also has large supplies of the PRVI Partisan 75gr .223 Match ammo. Price is $82.00 for 200 rounds (10 x 20-ct boxes), or $399.00 for 1000 rounds. The 1000-round price works out to $7.98 per 20 rounds.
Stan Widener tested the ammo and reports: “After firing, the brass was very clean and there was very little residue on the bolt carrier. Very clean powder. The ammo is made with MILAN BLAGOJEVIC powder and GINEX primers. There were no failures or misfeeds of any kind. All rounds functioned perfectly. The cases are very bright and shiny with military anneal mark. With no primer crimp to deal with, the brass should reload well. CONCLUSION: This is truly the best buy you can get in match 223 ammo.”
Great Price at AIM Surplus

Robert Whitley has produced a new video showcasing an AR15-based varminter chambered in the 6mmAR cartridge, a 6.5 Grendel necked down to 6mm (.243). In the video, Robert cycles through ten rounds (two magazines) loaded with Hornady 87-grain BTHP bullets (item 2442, 0.376 BC). The rifle features a custom 6mmAR upper with a side charging handle. Note the ease with which Robert operates the charging handle from the prone position. The 6mmAR cartridge allows an AR shooter to use high-BC 6mm projectiles with superior down-range energy. Robert offers complete uppers and other accessories. For more information and load data, visit 6mmAR.com.
Cerberus Capital Management, a large holding company, has acquired yet another gun maker, this time AR-platform builder DPMS Panther Arms. In the past year, Cerberus has purchased three gun manufacturers: Bushmaster Firearms, Remington Arms, and Cobb Manufacturing. It looks like Cerberus intends to be a major player in the semi-auto AR-platform market, Colt and FN Mfg. LLC notwithstanding. Strategically, the DPMS acquisition places Cerberus in an even stronger position to pursue military rifle contracts–the prize we believed Cerberus was chasing all along.
Randy Luth, DPMS founder and President, remarked, “We were looking for a partner that could enhance our expertise in operations and further develop our sales and marketing capabilities. Cerberus is a partner that can help us in those areas and provide the financial and operational resources required to expand our business. As we look forward, we see increased interest in our new calibers, based on the proven DPMS ‘LR’ rifle platform.” Based in St. Cloud, Minnesota, DPMS manufactures and distributes a complete line of AR15-based rifles and components, as well as rifle platforms in other calibers.
The Cerberus press release says, “Mr. Luth will remain President of the newly formed DPMS Firearms, LLC and will continue to oversee the strategic and operational aspects of DPMS.” We’ll see… after Cerberus bought Remington Arms, there was a high-level shakeup and Bushmaster honchos replaced many Remington top execs.
One positive aspect to Cerberus’ involvement in the gun industry is that the huge political clout Cerberus commands as the “rescuer” of Chrysler Corp. (which Cerberus also acquired) should undermine efforts to ban AR-platform rifles if the Democrats score big in the 2008 elections. Cerberus is big enough to make waves in Washington. Money talks in politics and Cerberus has lots of it.

(Remington, DPMS, and Bushmaster are all owned by Cerberus Capital Management, a private holding company.) The cartridge carries the “short, fat” design to the extreme. It is based on a shortened version of the .450 Bushmaster, which itself was a cut-down version of the .284 Winchester. Like the .284 Win, the 30 Remington AR has a rebated rim, so it will fit a .308 Win-sized boltface (0.473″). While it resembles a 30BR, the new case is much fatter, offering an impressive 44 grains of powder capacity. The portly diameter of the 30 RAR case dictates that the magazine will be a single-stack, and will hold only four (4) rounds.
