MidwayUSA has released a new 3-10x40mm MIL/MIL Tactical Grand Slam scope, made exclusively for MidwayUSA by Weaver. The scope features 1/10 mil radian (MIL) clicks, with a claimed 56 MOA (16.5 MIL) of BOTH windage and elevation adjustment. On sale through May 31, 2010 for just $299.00, the scope is regularly priced at $399.00. Even at the $400.00 mark, the scope is one of the most affordable optics combining a mildot reticle with mil-based clicks — a smarter system than what you find on so-called “tactical” scopes combining mildot reticles with 1/4-MOA clicks.
With the MIL/MIL arrangement you can directly translate what you see in the scope to click values. For example, with a MIL/MIL scope, a shot 1.5 mils low would require an elevation turret adjustment of 1.5 mils (15 clicks). This eliminates MOA conversions and allows the shooter to make adjustments quickly without having to do any math.
This tactical scope features Weaver’s Micro-trac® adjustment system, resettable 1/10 mil radian (MIL) windage and elevation turrets and a Mil-dot reticle. The scope has a one-piece tube and is claimed to be waterproof, fogproof and shockproof. The new Grand Slam 3-10X boasts a fast-focus eyepiece adjustment, and Weaver claims the multi-coated, Japanese-made lenses afford 94% light transmission. That’s a pretty tall claim regarding light transmission; if it’s true, then this scope should have very good low-light performance. We suspect the true average light transmission (across all visible wavelengths) is quite a bit lower. 94% transmission would put the new scope on a par with premium optics costing $1200.00 or more — which is unlikely. As noted above, the new 3-10x40mm scope is on sale for $299.00 for the rest of May, 2010. The scope is covered by Weaver’s Lifetime Warranty.

Weaver Optics, now owned by ATK, offers a new line of tactical riflescopes with First Focal Plane(FFP) mildot reticles, zero-reset turrets, and 5X zoom ratio. Weaver’s 4-20x50mm version (MSRP $994.49), delivers all those features for around $725.00 street price (SWFA.com). The smaller 3-15x50mm Weaver tactical scope (MSRP $890.95) sells for about $650.00 street price (SWFA.com).
These Weavers are attractive new options for tactical shooters. The pricing is very competitive considering these scopes have all the “right stuff” for tactical shooting: FFP, Mildot Reticle, Side Focus, and wide zoom range. We also like the new Weavers’ reset-to-zero turrets.
The new waterproof/shockproof/fogproof Weaver Tactical scopes feature one-piece construction, argon-purged tubes and multi-coated lenses with extra hard exterior coatings. For Tac Comps, the 5 times zoom ratio offers a very wide field of view for close-range or moving targets, yet plenty of magnification is “on tap” for long-range targets. The first focal plane reticle stays constant relative to the target at all magnification levels. This allows targets to be quickly ranged with mildots at any magnification setting.

 Weaver is the latest company to introduce a new series of Japanese-made optics with a high (5:1) zoom ratio. The new Super Slam series includes 2-10×50, 3-15×50, and 5-20×50 riflescopes, all offered with 1″-diameter main tubes and four (4) reticle options: Dual-X (med. duplex), Fine Crosshair (with dot), Illuminated Duplex, and Weaver’s proprietary EBX™ ballistic reticle. According to Tom Knudtson, Weaver Product Line Manager. “This new EBX reticle allows for accurate bullet trajectory compensation for long-range shots and is a perfect compliment to our 3-point erector system with improved spring design.” Among the new 1″-tubed Super Slams, we think our readers will be most interested in the 6-20x50mm. This 27.5 oz. scope features side-focus parallax control, extra-hard lens coatings, and “pull-up” turrets (no caps to lose). The 6-20×50 has 1/8-MOA clicks and 3 finishes are offered: Matte Black, Gloss Black, and Silver.
Tactical Super Slams Have Front Focal Plane (FFP) Reticles
There are two new Japanese-made Super Slam Tactical Models, the 3-15×50 (#800362), and the 4-20×50 (#800360). Both scopes feature 30mm main tubes, large fixed turret knobs (no caps), and a mil-dot reticle. Notably, both Tactical models have the reticle in the front (first) focal plane. This means the size of the reticle (and the mildots) remain the same (relative to the object viewed) at all magnification levels. That is an important feature for shooters using the mil-dots for ranging. FFP design is logical for a true “tactical” scope, and Weaver was wise to incorporate FFP into the Super Slam Tactical scopes. Weaver claims these Tactical scopes are waterproof, fogproof, and shockproof.

Readers often ask “What’s the difference between a Weaver scope rail and a Picatinny Rail?” The answer is not as simple as it seems. The dimensions of a Picatinny Rail should be consistent (from one rail-maker to another), since there IS a government spec. Conversely, there is some variance in “Weaver-style” rails. The width of the groove is the most important difference between Picatinny Rails and weaver rails. “Mil-spec” Picatinny rails will have a grove width of 0.206″ while Weaver rails typically have a narrower, 0.180″ groove width.
Brownell’s has a helpful GunTech Article that discusses the Picatinny Rail vs. Weaver Rail. That article explains:
“What are the differences between the ‘Picatinny’ and the ‘Weaver’ systems? The profile of the two systems is virtually identical. Depending on the quality of the machining done by the manufacturer, the two systems should be indistinguishable from the profile. The key difference lies in the placement of the recoil grooves and with width of the grooves. MIL-STD-1913 (Picatinny) grooves are .206″ wide and have a center-to-center width of .394”. The placement of these grooves has to be consistent in order for it to be a true ‘Picatinny’MIL-STD system. Weaver systems have a .180” width of recoil groove and are not necessarily consistent in a center-to-center measurement from one groove to the next.
In many instances, a Weaver system has a specific application that it is machined for, so interchangeability is not necessarily an issue. A MIL-STD-1913 system must adhere to the specifications listed above in order for it to be considered MIL-STD, since the military desires uniformity in the recoil grooves to allow for different systems to be mounted on the weapon with no concern for compatibility.
Now, what does this mean to you? Boiled down, it means that accessories designed for a Weaver system will, in most cases, fit on a ‘Picatinny’ system. The reverse, however, is probably not the case. Due to the larger recoil groove, ‘Picatinny’ accessories will not fit a Weaver system. There are, of course, exceptions to every rule, but for a good rule-of-thumb, [full-width] ‘Picatinny’ won’t fit Weaver, but Weaver will fit ‘Picatinny’.”
