The 6.8X43MM SPC II cartridge was developed as a part of the Enhanced Rifle Cartridge Program to address the deficiencies in terminal performance seen with 5.56x45mm NATO cartridge while allowing the soldier to carry the same number of rounds with a minimal weight penalty. By using a heavier projectile the 6.8 round offers more impact energy than the 5.56 NATO round across all effective ranges effectively bridging the gap in lethality between 5.56 NATO and 7.62 NATO.

A major drawback of using the 6.8 Cartridge in an M4 style weapon has been the lack of reliable magazines. To solve this issue we designed our SIX8 family of weapons around the magazine. Through a partnership with Magpul the leader in polymer magazine engineering we designed the first polymer 6.8 magazine. The SIX8 PMAG features many of the same design characteristics of the standard PMAG including the curved shape and familiar texture. The body is slightly wider and the walls were strengthened in critical areas. Our red follower makes the SIX8 magazine easy to pick out of a pile.

The SIX8 A5 brings together the best features of the LWRCI Enhanced and SPR models in one ready-to-shoot platform. SIX8 series weapons are short-stroke, gas piston operated rifles fully optimized for the 6.8X43mm SPC II cartridge. The A5 is designed with a low profile, two-position adjustable gas block allowing the shooter to compensate for running a suppressor with the added benefit of LWRCI’s longer, 12″ SPR-style modular rail system. With proprietary upper and lower receivers, this rifle has an enlarged ejection port allowing unhindered ejection of the 6.8 casings. The upper rail section has a cutback scallop design, allowing easy access to the low profile gas block while keeping the full 12″ modular rails available on the sides and bottom of the hand guards. Machined from the super alloy family of steel alloys most often used in aerospace, LWRCI raises the bar on reliability and ease of maintenance, delivering the highest level of performance. The gas-piston system can be accessed quickly by loosening two thumb screws. The dual control, fully ambidextrous lower receiver includes bolt catch and release, magazine release and fire control access from both sides. LWRCI Enhanced Fire Control Group comes standard, LWRCI Mark II Advanced Combat Bolt in 6.8 is nickel-boron coated, and the LWRCI NiCorr-treated, cold hammer-forged barrel is spiral fluted for weight and heat reduction. The SIX8 A5 come complete with LWRCI high efficiency 4-Prong flash hider, Skirmish BUIS, ambidextrous charging handle, Picatinny rail sections, LWRCI black polymer adjustable compact stock, Magpul MOE+ pistol grip, and Magpul PMAG 6.8 SPC magazine with high-visibility follower. This model has a 16.1″ heavy barrel and a Flat Dark Earth Cerakote finish on the receiver and handguard.

The LWRC Ultra Combat pistol grip is an enhanced grip for your next build or to update your current rifle. Its ergonomic design features over-molded snakeskin panels for superior grip and feel. Includes an internal storage compartment for small parts, tools and/or batteries.

LWRCI next evolution of their renowned Individual carbine family is the IC-MKII. Features updated design of the upper receiver and the adoption of the M-LOK mounting system for the handguard. The two position, adjustable gas block was updated to a paddle style and is now located inside the rail, easily accessed to select suppressed or unsuppressed. The proprietary Short stroke gas piston operating system delivers unmatched reliability in extreme conditions and is easy to maintain. MKII model is offered in a pistol configuration with a 12.70″ barrel and fitted with a SBA3 Brace.
