ALG Defense QMS trigger set drops in with no fitting required. Pull is consistent at around 6 pounds. Reset is positive and you can feel the click. Phosphate finish on all the steel parts. Solid budget upgrade from a basic milspec trigger.
ALG Defense QMS trigger was crisp but a little gritty for the first 100 pulls. Smoothed out after break in. Pull weight is around 5.5 lb. Reset is short. Solid budget upgrade from a basic milspec FCG once worn in.
wall is defined with a crisp break and almost no creep, reset is short and tactile. for a mil spec geometry trigger this is among the best you can get. drop in on a mil spec lower was clean, no oversize pin issues
ALG QMS trigger set has a noticeably shorter reset than a mil spec trigger which took some adjustment getting used to. Break is around 5.5 pounds. Good budget upgrade over standard milspec parts.
ALG Defense QMS trigger is a great range trigger with a clean break around 5.5 lb. A bit light for a true duty rifle in my opinion - I prefer more first stage take up for those applications. For a range or competition setup its excellent value.
ALG QMS trigger is a noticeable improvement over a basic milspec trigger. Break is smoother. Reset is short. Wish anti-walk pins were included since theyre a common pairing for ALG triggers.
