I have a aero 308 16" barrel and lower, shoots perfect without the suppressor. With my rugged radiant brass gets chewed up, out of a 100 rounds had a couple failure to ejects and a couple brass caught in the ejector causing it to mangle the round. Factory rifle for the most part, non adjustable gas block, shooting 168 gr smk‘s with 42 gr IMR 4064. Any ideas on a buffer and spring fix or do I need to add a adjustable gas block. Think the bcg is going to fast, using the can with a 556 or 300 blackout shooting supers or heavy subs no issues. Frustrating any thoughts would be appreciated!
