New
in box factory build LWRC SIX8-A5 10.5” Gas Piston AR Pistol in 6.8
SPC, part # SIX8A5PB10SBA3. 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 upper and lower receivers are designed to accommodate the slightly larger polymer magazine and to perfect the feed geometry for the 6.8 cartridge. As with the IC family, the weapons in the SIX8 family are fully ambidextrous. Our SIX8 rifles are, put simply, the familiar Stoner M4/AR-15/M16 architecture fully optimized for the 6.8 cartridge.
