i bought my m4e1 lower to day i have a question can you use detent spring and pin or do you need the pin spring and screw from areo
I’ve always just cut the length of the set screw off of the spring and it’s never been a problem. My sample size is only 3. But I do like your idea of only tightening to flush fit it.
Who in central Indiana keeps them in stock? I'm looking to purchase one for another build.
