Description
The Atrius ADG-FRS-S-MS is the single-sided, mil-spec-profile version of Atrius’s forced-reset selector, styled to match a traditional AR-15 safety lever (rather than Atrius’s more aggressive standard paddle) for retro builds, M16A4 clones, and Colt-pattern rifles. It delivers the same Safe/Semi/Super-Semi forced-reset function as the ambidextrous models, machined from heat-treated 4140 steel with a black nitride finish, and drops into compatible mil-spec/full-profile .223/5.56/.300 BLK fire control groups with no modification.
