The ALG Defense Quality Mil-Spec Trigger (ALG-QMS) is designed for those shooters where tradition, value and regulatory concerns are of primary importance. The pull of the QMS is very similar to a standard mil-spec trigger, however the majority of the associated grittiness of the stock trigger pull has been removed while the well known reliability of a stock trigger remains. The pull weight is not lower than the M4/M16 minimum weight specification of 5.5lbs.
The ALG Defense Mil-Spec (MS) Trigger is designed as a mil-spec option for OEM
and resellers who are using them for the purpose of builds. They are bulk
packed and sold in quantity of 50, with no instructions and no retail packaging.
