Product Information

The SI Defense Generation III billet upper and lower receivers are matched up for perfect lines and no slop.

The SI Defense billet lower receiver features an integrated solid trigger guard, a threaded bolt catch, and has been strengthened in several key areas. All SI Defense upper and lower receivers are precision CNC machined from solid 7075 billet aluminum and Type III hardcoat anodized per Mil-A-8625. The result is one rock-solid combo that shooters can count on.

Note:
  • The 308 receiver sets are compatible with DPMS LR-308 parts. DPMS magazine compatible set also works with Magpul 20LR Pmags. HK G3 magazine version works with G3 magazines exclusively.
  • The upper reciever has a High-Profile (older DPMS style) top rail, this will match up with SI defense railed handguards, and others designed for the higher reciever rails.
