Built this 300blk upper for pest control but decided to part ways since i never use it. Soecs are
Noveske 10.5" stainless barrel i took on trade from another member, pinned lo pro gas block thats a bit salty from previous owners removal. Roughly 100 rounds through it
Square forge upper reciever
Geissele mk4 rail
Keymo brake
Unknown bcg (9310 nitride) and milspec charge handle.
Functioned flawlessly and everythings been torqued to spec. The brake has rocksett but i can remove if not needed. Would prefer to sell with the bcg. One issue is the reciever is tight. Ive tried on all of my lowers with different takedowns and confirmed it was that. Honestly it isnt a big deal since it wasnt being shot much but worth noting and still a fun upper to shoot suppressed. Pp or venmo preffered, if you are local here in pa i travel and could probably meet and throw some deer/sub ammo in as well.
