Geissele Super 42 Braided Buffer Spring w/ H1 (3.8oz) buffer
I haven't gotten to do much testing with it beyond firing a few rounds to get the gas block adjusted to the proper setting to make it cycle correctly (had to take it 7 clicks out). So far I like how it shoots and I seem to have worked through the reliability issues (it wasn't picking up new rounds for a little while, even when I manually cycled it?). I have fairly limited experience with AR-15's, did I mismatch anything here? Any glaring issue? What about anything that isn't an issue but might be suboptimal?
Goal for this build was a jack-of-all trades plinking/defense gun, and I may use it in a 3 gun match at some point down the road. I wanted a softer recoil impulse/less muzzle rise with minimal gas in my face, hence the mid-length gas system and upgraded buffer spring. I want it to be able to cycle very quickly and reliably. But, I also want to be sure that it can handle all types of different ammo (adjustable gas block helps). The thing I'm most unsure about is what weight buffer I should have, given the gas port size, BCG weight, and the spring.
