Brownells 75th Anniversary - A Shooting Heritage

A Complete Lower Parts Kit and Drop-In Trigger Unit\

Why pay for components you won't use on your next AR-15 build? That's the position of CMC Triggers, and that's why they paired their AR-15 Lower Parts Kit with one of the company's Single-Stage Drop-In 3.5-pound AR-15 triggers.

Unlike standard AR-15 lower parts kits, the CMC Triggers option doesn't include a mil-spec trigger, hammer or the springs needed for either one. That way, those who are looking to add a CMC Trigger to their build won't have to buy a complete lower parts kit with pieces they won't use. Buyers can choose between curved or flat trigger bows. All that's needed now to finish your lower receiver is to add the grip of your choice!

NOTE: grip NOT included.
