CMMG Zeroed Lower Parts Kit Features The CMMG Zeroed Lower Parts Kit is built around CMMG s Zeroed line of enhanced AR-15 components giving builders upgraded parts rather than standard mil-spec equivalents. The extended bolt catch makes manipulating the action easier during reloads and malfunction clearing while the adjustable ambidextrous safety offers a choice between 60 and 90 degree throws to match a shooter s preference. An ambidextrous magazine catch and magazine release button accommodate both left and right handed shooters without additional modification. These upgrades give a completed lower a more refined ergonomic feel compared to a stock parts kit. Rounding out the kit are heavy duty pivot and takedown pins along with their detents and springs trigger and hammer retaining pins and a buffer retainer with spring. Every component needed to finish a stripped lower receiver build is included in this single kit simplifying the parts sourcing process for builders. Finished in black to match standard AR-15 finishes the kit integrates cleanly with most builds. For anyone assembling a custom lower receiver the CMMG Zeroed Lower Parts Kit offers a complete upgraded solution in one package.
