So I have purchased my first stripped lower. was planning to do an inexpensive AR build. Both of my current ARs have 2 stage triggers and I really like the feel. LPKs for standard triggers are $50-$60. 2 Stage LPKs are $140-$200. Question 1. Can a standard trigger be polished up to give a smooth pull? I know it won't be a true 2 stage, but at triple the cost I'm thinking of staying with the standard trigger LPK. Question 2. Who puts out a good standard trigger LPK. Was looking at DPMS.
