CMMG mil spec trigger kit is exactly the upgrade you need over the basic FCG that comes in a stripped lower. Hammer spring is the standard tension, sear engagement is correct. Drops in any milspec lower. Cant go wrong for the price.
CMMGs mil spec trigger kit is exactly what you expect - a standard mil spec break around 6 pounds. Reset is shorter than I expected which threw me off the first 50 rounds. Now Im used to it. Functional baseline.
standard mil spec single stage but with better than typical tolerances. wall is defined, no squish in the takeup, break is consistent. for the price of two beers its a no brainer upgrade kit
CMMG mil spec single stage trigger kit, way better than the no name LPK trigger that came with my budget lower. wall is defined, break is consistent at the listed weight. for under 50 bucks the upgrade is no brainer
