2020年9月7日 · I purchased an Aero M5 upper and lower and have a Wilson combat 20” barrel and bcg on the way. Rail is a centurion CMR, but I’m trying to see if they’ll let me swap for the mlok so I have a chance of clearing an adjustable gas block. My problem is, …

2025年4月3日 · Just completed a .308 12.5" SBR with adjustable Superlative Arms gas block running with and without Omega 300 suppressor. Currently running this setup with a standard Aero M5 carbine buffer kit. I am experiencing feeding and extraction issues.

2022年1月20日 · Hello. I recently put together an Aero Precision m5e1 chambered in .308 win. It has an 18" barrel with a rifle length gas tube. Mil spec carbine lower. The upper I bought complete and I put together the lower. Everything is Aero. It fires …

2022年7月19日 · I completed it with an Aero phosphate BCG and the Breach charging handle. I recently had it out for its maiden voyage to the range and was getting consistent failures to feed with both Lancer L7AWM and D&H 20 round magazines.

2020年7月2日 · As for bolt/bcg problems, if you take your carrier out you should be able to slide the bolt in and out without unreasonable effort. From the retracted position, just whipping the carrier in your hand should cause the bolt to extend.

2021年9月30日 · Suspecting it might be an issue with the Kali-Key's unusual gas key design (its gas key deflects gas away from the BCG instead of using it to impinge against the BCG, thus making it bolt action), a few days later, I tested it with the normal, NiB BCG in semi-auto configuration (legally) and this time the cycling issue manifested a bit differentl...

2022年4月8日 · I just finished putting together an Aero Precision M5 build and it is having some issues. When it does eject it dribbles out, if it ejects with any kind of speed (rarely) it is 1-2 o'clock but most times it will either spin the empty cartridge and then the BCG will pin it against the ceiling or the next round will pin it.

I have fired two brands of 150 grain 308 from two different magazines with failures to feed and the bolt not locking after the last round.
