The CMMG mil-spec AR-15 trigger (brand part no. 55CA7B9) is the standard trigger component for an AR-15 lower. CMMG builds it to mil-spec dimensions, which makes it a straightforward replacement when you are rebuilding a worn lower or assembling a new one. It is the trigger itself, so the hammer, disconnect, springs and pins are separate parts. Pair it with the rest of your lower parts to finish a build with CMMG parts.

Key Specifications

• The specification is mil-spec, so it follows the standard dimensions AR-15 lowers are built around.
• The platform is AR-15, as CMMG names the part.
• The coverage is the CMMG Lifetime Quality Guarantee that applies to all CMMG products.
