Thanks a lot for the info Survival shop! Ya was thinking about an adjustable gas block as well. My ultimate goal is to lighten up my sass and turn it into a hunting rifle. I have already taken 3 mule deer with it but it's way too heavy to carry on a long elk hunt. Another side question since I'm kinda new to reloading for a semi automatic. Is it completely necessary to crimp reloads? I have seen mixed info other places. How do people shoot non-cannelured match bullets? Do ya just put a light crimp on these? Born and raised on bolt guns and black powder muzzleloaders. Kinda new to ARs. Thank you everyone for the warm welcomes!
