Description
This product is BUILT TO ORDER - Shipping will occur from 7 to 10 Business Days after purchase.

Atrius Forced Reset Selectors (FRS), also known as Super Selektor or Super Selector devices, are selector-based "super safety" systems for AR-15 platforms (primarily .223/5.56/.300 BLK). They replace the standard safety selector design (SAFE, SEMI for normal semi-auto, and SUPER-SEMI/FULL-SEMI for forced reset mode). This uses a cam/trip arm mechanism that mechanically forces the trigger to reset via BCG movement, enabling faster follow-up shots while keeping your existing mil-spec or compatible fire control group (FCG).


* Heat-treated 4140 steel with corrosion-resistant black nitride finish for durability in harsh conditions.
* Mechanically leveraged for reduced wear on internals compared to full forced reset cassette triggers; drop-in install (minor fitment sometimes needed).

M16 or Standard/Single Switch: Basic right-side lever (textured ergonomic or mil-spec style).
Ambi Switch: Fully ambidextrous levers for left-handed or versatile shooting.
