LWRC SIX8PRB8 SIX8 A5 6.8 SPC II 30+1 8.50″ Black Nitride Threaded Barrel, Picatinny Rail Receiver, Buffer Tube Black, Magpul+ Grip, Ambidextrous

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. 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 upper and lower receivers are designed to accommodate the slightly larger polymer magazine and to perfect the feed geometry for the 6.8 cartridge. The weapons in the SIX8 family are fully ambidextrous.
