I want to share my experience with the "15 minute trigger job" that's being touted on the internet as an inexpensive, but effective way to lighten the pull on your AR. Part of it involves cutting one of the legs of the hammer spring. Technically, it does reduce the pressure or force on the sear and hammer, but it also reduces the stored energy required to fire off the primer. After firing almost 80 rounds from my DPMS 6.8SPC, I'm more than convinced that the occasionally misfire I get is from the reduced force. Most showed a respectable indentation, however when the dent was so slight that it was obviously a light strike, it was my wake-up call. Before anyone looking to snipe and criticize me jumps in, let me admit that was a dumb-assed thing to do. The good news is a new spring costs only $1.50! Thought I'd save others the trouble of finding out for themselves.
