The dual-charging PSC-12™ upper assembly features all the utility and advantages of its predecessor, the PSC-11™, available now for large-frame AR platforms in both the DPMS LR-308 and the Armalite AR-10/Knights Armament SR-25 patterns. On the heels of the JP side-charge system’s success on our other rifles, the PSC Series not only offers a unique new take on this feature by incorporating both side-charge and traditional top-charge systems into a single upper receiver, but also by making this innovation cross-compatible with existing DPMS, Armalite and Knights Armament lower assemblies. The PSC-series combines the great features and performance of virtually our entire rifle line into a single package designed for the all-out tactical market with its redundant charging systems, dust cover and forward assist. In addition, the PSC-12™ is also available as a complete rifle built on a modified version of our LRP-07™ billet lower with the full selection of stock, grip and trigger options available.

Midwest Industries MI-10

Midwest Industries has recently announced the addition of a .308 AR rifle line to their existing selection of quality production firearms. The MI-10 is currently available with a 16” barrel configuration, but plans are currently in the works to add an 18” and 20” model.

The new MI-10 will incorporate a Criterion-manufactured 416R stainless steel barrel with a salt bath nitride surface finish for extended barrel life and added corrosion resistance. 16” and 18” variants will feature a 1-10 twist, while the 20” model will come standard with a 1-11 twist rate. Each rifle will feature CBI’s M118 LR chamber, giving shooters the option to use both .308 Win and 7.62×51 NATO ammunition. The M118 LR chamber incorporates a slightly longer throat than the SAAMI .308 Win design, allowing shooters to effectively run loads with heavier bullet weights.

Weighing in at a respectable 8.5 lbs unloaded, the MI-10 features Magpul furniture and a Midwest Industries floated handguard. The MSRP for these rifles is listed at $1,699, but they will be available for purchase from Midwest at an introductory rate of $1,599. A small selection of the 16” MI-10 rifles are currently available for local purchase from the Midwest Industries Waukesha showroom. The full web release is still pending, but the rifles should be available for purchase from www.midwestindustriesinc.com shortly.

Knights Armament Company

Knight’s Armament Company (KAC) is an American firearms and firearms parts manufacturer, best known for producing the Rail Interface System (RIS) and the Rail Adapter System (RAS) grips for firearms use. They currently produce a variety of firearms, specifically rifles built on the AR-15 platform. One of their best known rifles is the SR-25 semi-automatic special application sniper rifle.

KAC is owned by C. Reed Knight and is based in Titusville, Florida. Knight’s Manufacturing Company (KMC) is the division of KAC responsible for products aimed at the civilian market.


KAC SR-25

The KAC SR-25 (Stoner Rifle-25)is a designated marksman rifle designed by Eugene Stoner and manufactured by Knight’s Armament Company.

The SR-25 uses a rotating bolt and a direct impingement gas system. It is loosely based on Stoner’s AR-10, rebuilt in its original 7.62×51mm NATO caliber. Up to 60% of parts of the SR-25 are interchangeable with the AR-15 and M16—everything but the upper and lower receivers, the hammer, the barrel assembly and the bolt carrier group. SR-25 barrels were originally manufactured by Remington Arms with its 5R (5 grooves, right twist) rifling, with twist 1:11.25 (1 complete turn in 11.25 inches or 286 millimeters). The heavy 24 in (610 mm) barrel is free-floating, so handguards are attached to the front of the receiver and do not touch the barrel.

First military purchase was spearheaded by the U.S. Navy in the early 1990s; the first operational deployment and use of the SR-25 sniper rifle was with U.S. Navy SEAL snipers supporting operations in Somalia in 1993.

Below is a list of Knight’s Armament current 7.62×51 lineup.

KAC SR-25 History

In the late 1950s, Eugene Stoner designed the AR-10 battle rifle to equip U.S. troops. It was accurate for an auto-loading rifle, but it lost the competition to the M14 rifle. The patent rights for the AR-10 and the AR-15 were sold to Colt’s Manufacturing Company. Colt focused on the AR-15, giving others the ability to capitalize on the AR-10 system.

In the early 1990s, Stoner joined Knight’s Armament Company. He continued his AR-10 design work and joined it with the direct gas system of the AR-15. The end result was the SR-25 (adding together the numbers of the AR-10 and AR-15) which improved the AR-10 design with M16A2 advancements and parts commonality. The original SR-25 was released in the early 1990s and had a heavy free-floating 24 in (610 mm) match grade barrel with a fiberglass handguard. It had a flat top upper receiver with a Mil-Std 1913 rail for mounting optics and a 2-stage match grade trigger. The bolt carrier was similar to the AR-10’s, being chrome plated and having a captive firing pin retainer pin. The SR-25 was designed specifically to fire 168 gr (10.9 g) open-tip match cartridges. Accuracy was guaranteed at or under 1 minute of angle. At first, AR-10 type 20-round magazines were used, but they were later replaced by steel 20-round magazines resembling those used by the M16.

The United States Special Operations Command took interest in the SR-25, particularly its high magazine capacity and faster engagement time compared to bolt-action rifles. After some modifications, SOCOM adopted the SR-25 as the Mk 11 Mod 0 in May 2000. Changes included a shorter 20 in (510 mm) barrel that could fire M118 and M118LR 7.62×51mm NATO rounds and had a quick detachable sound suppressor mount. An 11.35 in (288 mm) free-floating handguard rail system allowed mounting accessories. Flip-up front sights and adjustable back-up iron sights were added, and an M16A2 stock and pistol grip were used.

Beginning in mid-2011, SOCOM began divesting the Mk 11 Mod 0 from their inventory and replacing it with the SSR Mk 20, the sniper variant of the FN SCAR. The Mk 11 is to be completely replaced by 2017.


KAC SR-25 Design

The SR-25 enhanced match rifle utilizes the newer URX II Picatinny-Weaver rail system, rather than the older Mk 11 free-floating RAS, on the top of the receiver to accept different scope mounts or a carrying handle with iron sights (front sight mounted on the rail located on the forward end of the non-modular handguard).[4] The match version is designed to shoot at a precision of 0.5 minutes of angle, which corresponds to 0.5-inch (13 mm) groups at 100 yards (91 m).

The Mk 11 Mod 0 system is chambered for 7.62×51mm NATO, and is designed for match-grade ammunition. The Mk 11 system includes the rifle, 20 round box magazines, QD (Quick Detachable) scope rings, Leupold Mark 4 Mil-dot riflescope, Harris swivel-base bipod on a Knight’s mount, and QD sound suppressor, which is also manufactured by Knight’s Armament Co.[1] Flip-up BUIS (Back up iron sights) are attached to the modified gas block and upper receiver.

The Mk 11 Mod 0 utilizes an Obermeyer 20 in (510 mm) match target barrel, along with a RAS (Rail Accessory System) fore-end made by KAC, consisting of an 11.35 in (288 mm) long match fore-end. The RAS allows for quick attachment/detachment of MIL-STD-1913 components. The aluminum fore-end makes no contact with the barrel forward of the receiver, allowing for extreme accuracy. The Mk 11 Mod 0 has an empty weight of 15.3 lb (6.9 kg), and an overall length of 45.4 in (115 cm). The civilian version, using the longer 24 in (610 mm) match barrel, is guaranteed to produce groupings of less than 1 in (25 mm) at 100 yd (91 m), or 0.3 angular mil, using factory match loads.

During the Iraq War, the United States Marine Corps ordered 180 Mk 11 Mod 1 rifles. These were Mk 11s equipped with the upper receiver of the M110 Semi-Automatic Sniper System. The M110 upper gave the Mk 11 Mod 1 a URX modular rail system and a flash suppressor on the barrel. These saw limited use before they were phased out when the Marines chose to purchase the Mk 11 Mod 2, which was simply the USSOCOM and U.S. Navy designation for the complete M110 rifle.[5]

The new SR-25 Enhanced Match (E.M.) Carbine is very similar to the KAC M110 Semi-Automatic Sniper System,[4] though the M110 utilizes the newer URX Rail system, a length-adjustable fixed buttstock, and an integrated flash suppressor. Starting late 2011, USMC snipers will replace Mk 11 Mod 0 rifles with the M110 on a one-for-one basis.

Heckler & Koch HK MR762A1

Heckler & Koch HK MR762A1

Like its 5.56 mm counterpart, the Heckler & Koch HK MR762A1 is a direct descendant of the Heckler & Koch 416/417 series, only in a semi-automatic rifle configuration developed for civilian users.

Using the Heckler & Koch -proprietary operating system, the HK MR762A1 is gas operated and uses a piston and a solid operating “pusher” rod in place of the common gas tube normally employed in AR15/M16/M4-style weapons.

Pioneered by Heckler & Koch in the G36, HK416, and HK417; this method virtually eliminates malfunctions common to direct impingement gas systems since hot carbon fouling and waste gases do not enter the receiver area. The MR762A1 stays cleaner, reducing heat transfer to the bolt and bolt carrier, and drastically reducing wear and tear on other critical components. The service life of all parts is increased substantially.

HK MR762A1 AR-10 308AR

HK MR762A1

The HK MR762A1 uses a barrel produced by Heckler & Koch’s famous cold hammer forging process. This manufacturing process uses the highest quality steel, producing a barrel that ensures superior accuracy, even after firing thousands of rounds. The MR762A1 is produced at Heckler & Koch’s American manufacturing facilities from both American and German-made components.

The HK MR762A1 uses many of the assemblies and accessories originally developed for the HK416/417 series including adjustable buttstocks, ergonomic pistol grips, mechanical sights, and the HK free-floating four-quadrant rail system/handguard. This MIL-STD-1913 “Picatinny” type rail system allows all current accessories, sights, lights, and aimers used on M4/M16-type weapons to be fitted to the MR series. The HK rail system can be removed without special tools by the user and ensures 100% return to zero when reinstalled.

Ambidextrous operating controls are standard on the MR762A1, including a convertible charging handle and an ambidextrous selector lever. The MR762A1 uses the same 10- and 20-round translucent polymer box magazines made for the HK417; a 5-round magazine is also under development. MR762A1 rifles are well-suited for a variety of applications including law enforcement tactical, police patrol, general sporting, and hunting (a 5-round magazine is under development).

We use the same grade steel used in making cannon barrels — for its rifle barrels. Using the famous HK cold hammer forging process, this advanced technology manufacturing produces a barrel that provides superior accuracy and long service life. It is also moderately “swagged” with a slightly smaller internal diameter at the muzzle end than the chamber end. This has a positive effect on bullet accuracy and velocity and the thick, heavy contour MR series barrels also contributes to its precision.
