CMMG AR-15 Gunbuilder’s Lower Parts Kit

The Gunbuilder’s kit from CMMG includes all the essential lower receiver parts you need for your next AR-15 build. The only things not included in this kit are the commonly upgraded parts, which include a trigger, hammer, fire control group, disconnector and pistol grip. Every component meets or exceeds mil-spec, and this particular kit is ideal for shooters who don’t use a standard A2 grip.

• Takedown pin

• Bolt catch, plunger, spring & spring pin
• Receiver pivot pin
• Selector detent
• 2x takedown detent pins & springs
• Magazine catch, spring & release buttons
