The CMMG AR-15 Lower Parts Kit has everything needed to populate a stripped mil-spec AR-15 lower receiver, including the fire control group and a pistol grip. Use it to finish a new build, or keep it on the bench as a source of spare springs, pins and detents.

All parts meet or exceed mil-spec, so they fit the standard pockets and pin holes of a mil-spec lower, and the trigger group gives you a standard single-stage pull.

Features:

• Trigger, hammer, disconnector, and trigger/hammer springs
• Trigger guard
• Safety selector
• Bolt catch with spring and plunger
• Magazine catch, spring, and button
• Pivot and takedown pins with detents and springs
• Buffer retainer and spring
• Pistol grip included
• All parts meet or exceed mil-spec

Fits mil-spec AR-15 stripped lower receivers chambered in .223/5.56. The buffer tube, buffer, spring and stock are not included. After assembly, function-check the safety in both positions, trigger reset and hammer follow before live fire.
