Description
The Atrius FRS replaces your safety selector and gives your AR three modes: safe, semi and forced reset — so you can switch back to a normal semi-auto trigger anytime.
It’s sold as a drop-in, but real rifles have real tolerances. We fit and tune it to your rifle, function-check it and test-fire it before it goes back to you. If your rifle shows bolt bounce, we tune the buffer system and charge only for the buffer weight and spring it needs.
Left-handed or want controls on both sides? Choose the ambidextrous selector (+$50).
Atrius FRS, fitting, tuning and test fire included. Fits mil-spec AR-15 lowers.
Not available to customers in states where FRTs are prohibited — see our Shipping Policy.
Return shipping: flat $50, added at checkout — or free if you choose local drop-off and pickup at our Calhoun shop.
