M-K IIA2 GEN2 Tactical Trigger from The Wisconsin Trigger Co.
Gear Review by Johnny Fisher
Do you shoot an AR-platform rifle? Here’s an excellent trigger upgrade option that has recently returned to the marketplace. The Wisconsin Trigger Company (WITC) has resumed production of the legendary Milazzo-Krieger M-K II trigger for the AR-platform rifles. Not merely marketing a replica of the original Milazzo-Krieger design, Wisconsin Trigger now offers an enhanced, drop-in version called the M-K IIA2. An easy install, the Milazzo-Krieger trigger drops in with no special tools or machining required (and no modification of the safety selector switch).
For those who are looking for an extremely crisp AR15 trigger that closely mirrors the “feel” of a finely tuned M1 / M14 trigger, this trigger might be the solution. The first stage is exceptionally clean and smooth due to a proprietary diamond-grinding process. I felt that the first stage travel was longer than a Geissele, but many guys will prefer that. Upon reaching the very noticeable and defined “wall” of the second stage, a further increase of pressure provides the instantaneous snap one looks for in a high-quality trigger — complete with a total absence of anything resembling creep or slop.
If you follow the instructions in the box and watch WITC’s informative how-to videos, installation of this trigger is extremely straightforward, requiring no special tools or fitting.
As supplied straight from the factory, the first stage requires about 2.25 pounds of take-up before encountering “the wall” of the second stage. For this purpose of this review and to ensure “making weight” in CMP Service Rifle Competitions, the (white) 5-lb. disconnector spring was used. The weight of the second stage came in right at an extremely repeatable 5 lb. 3 oz. (averaging +/- 1.5 oz.) for a ratio of about 40/60 between the two.
Upon release of the hammer, the disconnector reset is decidedly short. National Match shooters in particular will appreciate the very short but easy-to-recognize trigger reset during rapid-fire strings.
Tuning the Trigger Before Installation
As with most National Match-grade triggers on the market, the Millazo-Krieger utilizes proprietary pins that come supplied with this unit. They must be used for final installation and are purposely oversized to a specific diameter for a very snug fit. This is to ensure the trigger and hammer rotate solely on the pins, as opposed to the pins eventually rotating inside the receiver. It is best to use standard sized mil-spec trigger and hammer pins for the setting of tensions (trigger weight) before final installation to help avoid undue wear to the receiver pin holes. Final adjustment of second-stage pull weight must be done BEFORE final installation.
It is recommended to first set the amount of desired disconnector engagement by performing a very simple process that is detailed in the included installation instructions from the TOP of the trigger. The swapping out of disconnector springs and final tuning of the second stage can then be done, but only from UNDERNEATH a disassembled trigger.
The disconnector tensioning springs are easily swapped out by removing the spring plug from the bottom of the trigger housing that exposes the spring pocket. After inserting the desired weight spring, the spring plug must be installed at least flush with the bottom of the trigger housing. Installing it deeper will add trigger pull weight on the second stage. Installing it too shallow will interfere with trigger movement.
Transferable Warrnty:
The Wisconsin Trigger Company offers a full lifetime warranty to all unaltered parts of its triggers. This lifetime warranty is fully transferable when the trigger is sold to a new user! When have you heard of an AR component manufacturer with a transferable warranty — we’re impressed.
Not just a retailer, John Scandale of Keystone Accuracy is a distributor of these triggers. He currently has many in stock and for sale at a very special introductory price.
What Comes in the Box:
The $265.75 trigger kits come complete with everything you need: Trigger unit assembly, trigger return spring, full strength hammer spring, two proprietary oversized trigger & hammer pivot pins and three disconnector tensioning springs (3.25 lb., 4.5 lb., 5.0 lb.). Also included is a comprehensive installation manual, a color-coded disconnector spring selection chart, some promotional items, and the lifetime warranty card.
Here’s an AR configuration suited to the new AR Mid-Range Prone Discipline: Moderate-length barrel, Harris Bipod, Leupold Mark AR MOD 1 4-12x40mm scope. Photobucket image by Ingo1978.
The NRA has created a new mid-range, target-shooting discipline for AR owners. The provisional rules for the new AR Mid-Range Prone Competition will allow calibers from .22 up to .308. Rifle weight will be limited to 14 pounds. Competitors may use Harris (or similar) compact, “tactical” bipods, and optics up to 12-power will be allowed (but iron sights can also be used). The goal of this new competition is to get the many AR owners to the range to compete.
The NRA’s Information Sheet for the new mid-range discipline explains: “These rifles are of the ‘AR-Platform’ variety, semi-automatic, chambered in any caliber from .223 cal./5.56mm. up to and including .308 cal./7.62mm. The courses of fire will be the same courses of fire currently used for other NRA Mid-Range (Prone) High Power Competition (300, 500, and 600 yards) and are designed to be fired concurrently with other forms of Mid-Range competition. The targets will be the same targets that are used for Service Rifle, Match Rifle, and Palma Rifle Mid-Range Prone competition. Mid-range telescopic sights will be allowed, but not required. Because this is prone competition, shooters may use tactical front rests such as Harris-type bipods and limited rear rests of the type one might find used in military or police tactical situations.”
A very prominent NRA member who works with the Competition Committee recently posted this explanation of the new AR discipline on our Forum:
NRA Mid-Range (Prone) Tactical Rifle (AR)
For those clubs and match directors who have members with ARs who want to shoot Mid-Range Prone but who don’t want (or can’t afford) to shoot traditional “sling” or F-Class, we have a new opportunity to get those ARs out of the closet and onto the range with very little in the way of additional costs:
It’s called Mid-Range Tactical Rifle (AR). A copy of the description and the Rules (Provisional) are attached as a PDF file and should be published by the NRA very soon. CAUTION — these are NOT official — but I think they are accurate:
In brief, here’s how it works:
1. The event will be fired concurrently with any other Mid-Range event, alongside of F-Class and “sling” divisions.
2. The Event will be fired on the “sling targets”.
3. AR Rifle General Standards:
Calibers: 223/5.56 up to and including .308/7.62mm
Weight: Overall weight not more than 14 pounds
Support: Harris-type “tactical bipod” (no large F-Class bipods).
Optics: Scope not more than 12X
Barrel: Not more than 20″
Trigger: Trigger pull not less than 4.5 pounds
4. This is NOT F-Class — this is designed to be closer to “tactical”. F-Class competition gear is generally illegal; competition stocks are generally illegal. [The event] is designed to attract more law enforcement and/or military (maybe local National Guard?) and other “tactical shooters” out to the range shooting for precision. For more info, check out the attached PDF file.
You’ll find a discussion of this new AR Mid-Range discipline in our Shooters’ Forum, HERE: AR Mid-Range Match Forum Thread. Here are some interesting comments from that thread:
“Opening up mid-range matches for ARs is a great idea. I’m not an AR guy myself, but I have lots of shooting friends who are. They tend to have a lot of ideas what their guns are capable of out to 600 yards, but most don’t take many opportunities to shoot them at those ranges, and none of the existing High Power disciplines are very appealing. Until now. I hope it doesn’t become an equipment race. A 185/200 is a respectable score even with a 12″ 10 ring. I hope everyone is supportive — helping get these guys on the paper and providing positive feedback even for scores that seem modest by F-Class standards.” — Comment by Berger.Fan222
“It looks like the recommended targets will be the same as conventional shooters use (i.e. ~1 MOA X-ring). Given the specifications for rifles/bipods/scopes/etc., I think this would be an appropriate level of difficulty to start. It will be challenging, particularly at 600 yards, but by no means impossible. Of course, at 600 yards, anyone shooting an AR15 (.223/5.56) will be at a disadvantage to ballistically-superior calibers unless they come up with a good way to load 80+ grain bullets that will mag-feed. Personally, I’d like to see this limited strictly to .223 ARs. Almost everyone has one and the mag feed requirement would really keep things even across the board. The inclusion of other calibers will allow this to become a ‘caliber race’ in that .223 will have a very hard time keeping up with other, better calibers at 600 yards.” — Comment by gstaylorg
“Looks like a great new addition. The PDF document says rule 7.20 for course of fire which is mid-range slow fire. I believe all slow fire is currently ‘one round loads’. The PDF explicitly states 10-, 20- or 30-round magazines and no sleds. Does anyone know if this new discipline would be fired from magazine or one-round loads? Shooting from magazine would be keeping with the ‘tactical’ aspect and enforcing mag-length loads. But it does not seem to jive with the ‘one round load’ currently stipulated for slow fire?” — Comment by Highpower-FClass
AR-platform rifles can be maintenance-intensive beasts. But some AR owners make the situation worse by not regularly cleaning important small parts, or by using too much oily/greasy lubricants in the wrong places. A properly maintained and lubricated AR15 can shoot hundreds of rounds (between cleanings) without a problem. If you learn where (and where not) to apply lubricant, you’ll find that your AR will run more reliably and the task of cleaning the bolt and bolt carrier will be less of a burden.
Here is a good video that explains AR-15 Cleaning and Maintenance. In this 30-minute NSSF video, Gunsite Academy instructor and gunsmith Cory Trapp discusses the proper way to clean and maintain the AR-15 carbine. Very knowledgeable, Trapp provides rock-solid advice for AR owners. Along with cleaning producedures, this video explains how to inspect key components and how to function-test your AR before each shooting session.
At the request of our readers, we have launched a “Deals of the Week” feature. Every Monday morning we offer our Bargain Selections. Here are some of the best deals on hardware, reloading components, and shooting accessories. Be aware that sale prices are subject to change, and once clearance inventory is sold, it’s gone for good. You snooze you lose.
1. 6mmAR.com — Easy-Change Front Bag-Rider for ARs
Here’s a great product from our friend Robert Whitley at 6mmAR.com. This new device is a 3″-wide, flat-bottomed, front bag-rider that mounts to your AR in seconds, without tools. The bag-rider (aka “sled”) really works — stabilizing your AR when shooting from a front pedestal rest. We recommend using the front sled during load development and whenever shooting from the bench. The bag-rider attaches to your AR’s handguard with a Velcro strap, indexing on the bipod stud. Right now the Easy-Change Bag-Rider has an introductory price of $55.00. If you own an AR, you should get one.
2. Target Sports — Federal .22 LR Ammo, 325 Rounds for $24.90

Everyone should have an accurate .22 LR target pistol. This German-made GSG 1911 22LR pistol shares the look, feel, and ergonomics of J.M. Browning’s classic model 1911 so it’s good for cross-training. We’ve tried this pistol and the trigger is pretty darn good — though don’t expect it be be as nice as a S&W Model 41. But consider that the GSG costs just $249.99. By contrast, MSRP on a new Model 41 is a steep $1369.00. For cross-training and target work the GSG is a very good value.

Here’s an interesting project — using a second-hand barrel to upgrade an AR15. Our friend Erik Cortina decided to make his AR15, originally chambered in 6.8 SPC, into a 6.5 Grendel. Erik acquired a “pre-owned” 6.5-06 match barrel through our Shooters’ Forum. Erik inspected the barrel with a bore-scope and confirmed it was in good shape after the first few inches (past the chamber). The 6.5-06 barrel had more than enough length, so he trimmed off the chamber end, then contoured the barrel to fit his AR15. This is a smart way to upgrade a gun without spending $350 or more on a brand new barrel.
In the first video, Erik explains the process of converting his 6.8 SPC AR15 into a 6.5 Grendel: “I take the upper completely apart and pull barrel off which will be used to take dimensions for new barrel. The new barrel will be turned from an old competition heavy barrel. All the barrel reaming will be done using JGS reamers. I will also use JGS reamers to make a seating and F/L sizing die.”
In the second video, Erik contours the “pre-owned” barrel to fit his AR. He uses an old bolt-action 6.5-06 competition barrel and cuts it to 17″ long and contours it to fit his AR-15. The barrel is turned down on a manual lathe to .750″ outside diameter for the majority of its length in order to fit the gas system barrel block that is made for a .750″ barrel. After contouring, the barrel will be threaded and chambered.

The CMP has just released proposed 2016 Competition Rules. There are a number of important proposed changes, some quite controversial. Topping the list are rule changes that would allow optics for service rifles and “modern military rifles” (MMR). If these changes are adopted, Service Rifle shooters and modern military rifle shooters will be able to use scopes up to 4.5X power. Rifle weight limits will be increased slightly to allow for the optics and the definition of “Service Rifle” will be liberalized to allow more AR variants. In addition, collapsible or adjustable-length stocks will be allowed.
We want to stress that these new rules have NOT been set in stone — not yet at least. The CMP issued its notice of Proposed 2016 Rule Changes to inform competitors and invite feedback. The CMP asks that comments/questions be sent to competitions @ thecmp.org, not later than November 13, 2015.
Major Proposed Rule Changes
1. Optical Sights For Service Rifles
The CMP states: “For several years, the CMP has recognized that optical sights are the wave of the future for Service Rifle shooting. Military recruits today do all of their training with optical sighted rifles. Service Rifle rules have traditionally tried to keep abreast of military rifle and training developments so opening Service Rifle shooting to optical sights became an inevitable change.” The 2016 rules will, for the first time, permit M16/AR15-type rifles to have optical sights (fixed power or zoom) with a maximum magnification of 4.5X and an objective lens no larger than 34 mm. There will not be a separate class for scope-sighted rifles. Instead, competitors will have a choice of using either a scope-sighted rifle that weighs no more than 11.5 pounds or a metallic-sighted rifle that will continue to have no weight limit.
2. More Options For M16/AR15-Type Rifles
Since accurized Service Rifles first came into popular use in the 1950s and 1960s, those rifles, whether M1s, M14s, or M16s and their commercial equivalents, have been rigidly defined. Legal M16-type service rifles had to retain the external profile of an M16A2 or M16A4 rifle and could only have modifications that were explicitly permitted in the rules. All this will change in 2016. The CMP plans to liberalize the Service Rifle rules to encourage greater participation. A wider variety of commercial AR-platform rifles will be allowed so long as they meet basic requirements, such as 20″ max barrel length, 5.56x45mm (.223 Rem) chambering, and a trigger pull of at least 4.5 pounds. Notably, the rifles can have either a gas-impingement system or a piston-operated gas system. Collapsible stocks will be allowed. However butt-plates and cheek-pieces may not be adjustable. (See all Requirements HERE).
3. Optical Sights for Modern Military Rifles (CMP Games)
One of the fastest growing rifle competition categories is for Modern Military Rifles. There are two classes, one for M16/AR15 platform rifles and one for a broad range of other military rifles. Competitors who compete in Modern Military Rifle Matches will now have the option of using optical sights with a maximum magnification of 4.5X. To make allowance for the increased weight of telescopes, the weight limit for AR-type rifles was increased to 8.5 pounds and for M-14/M1A rifles to 10.0 pounds. (This is a CMP Games limit — a different Rule than the Service Rifle Rule).
4. Stocks for Modern Military Rifles
Butt-stocks on these rifles may vary in length and collapsible or adjustable-length stocks will be allowed. Butt-stocks, however, may not have butt-plates or cheek-pieces that adjust up or down.
No Changes for Pistol, Vintage Sniper, or Rimfire Sporter Competitions
While big changes are slated for the Service Rifle and MMR disciplines, the CMP is not making significant rule changes for other popular CMP shooting sports.
Pistol Rules Are Unchanged
Except for permitting service pistols to have a Picatinny rail below the barrel, the Service Pistol and 22 Rimfire Pistol rules adopted in 2015 are unchanged.
Vintage Sniper Rifle Team Match Rules Are Unchanged
According to the CMP, Vintage Sniper Rifle Match rules “have stabilized nicely in the last two years” so there will be no 2016 rule changes for the Vintage Sniper two-man team event.
Rimfire Sporter Rifle Rules Are Unchanged
The most popular rimfire rifle match in the country continues to attract impressive numbers to its matches. Like the Vintage Sniper Rifle Team Match, these rules have now stabilized so that there are also no 2016 rule changes in Rimfire Sporter.
