CMMG AR-15 Gunbuilder's Lower Parts Kit Mil-Spec Builder Kit No Grip Fire Control Group 55CA601

The CMMG AR-15 Gunbuilder's Lower Parts Kit is designed for builders and armorers who want the essential, mil-spec small parts needed to complete or repair an AR-15 lower receiver while leaving out the commonly upgraded components. This kit intentionally excludes the trigger guard, fire control group, and pistol grip so you can choose your preferred aftermarket options while still covering the core hardware required for a reliable lower build.

• Mil-spec lower receiver small parts for AR-15 builds and repairs
• Builder-focused kit excludes commonly upgraded parts (pistol grip, trigger group, and trigger guard)
• Includes key assemblies like bolt catch components, magazine catch components, selector components, and takedown/pivot parts
• Great for completing a lower or replenishing spares for maintenance
• All parts meet or exceed mil-spec standards
