Description
The D-6.8 Billet Lower Receiver is an ideal choice for starting a 6.8 SPC AR build. Precision machined from a solid block of 7075-T6 billet aluminum and finished with hard-coat black anodizing per Mil 8625 Type 3 Class 2 specifications, you can be sure that this unit is as tough as they come. 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. 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 between 5.56 NATO and 7.62 NATO.
