The ALG Quality Mil-Spec Trigger is designed for shooters and armorers who are in need of a reliable trigger that meets mil-spec standards for AR-15 triggers. The QMS is an enhanced standard trigger which ensures that maintenance and installation procedures are similar to current mil-spec triggers. The QMS shares common parts with stock triggers, and trigger assembly parts may be interchanged between QMS triggers since there are no matched sets. The ALG QMS trigger meets the standard for US military triggers for the M4 carbine, and is safe for units or departments to use instead of poor performing stock triggers while keeping their rifles in compliance.
