Well, parts came in and didnt work as planned. 1.) Hammer spring was for AR15, didnt work with M16A2 hammer sprocket on right side of the hammer. Emailed brownells to see if they have a correct spec spring. 2.) Only came with one disconnector spring, which kinda tells you also that the kit is intended for AR15 only and not for an M16; M16 requires two but for shooting semi auto you would only need to swap out one spring. In the end, I only left the trigger spring installed, and it seems that with only that spring the trigger pull became heavier...dont have a scale due to late household goods shipment, but by the calibrated trigger fingers God gave me a regular trigger group doesnt neccessarily feel much lighter, but it does feel better to use. I decided to take the spring out and put the regular spring back in, and keep this spring kit for a semi auto AR, maybe itll work for that. Im glad it only cost me $2.35 for the kit, not a big loss.
Spring Kit from Brownells, P/N 989-000-001, might be worth it on an AR.
