Put 120 rounds through it today 90 supers 30 subs. Shot the subs last, zero malfunctions, brass looks good. Locked back on empty every time.
Hackjob got some upgrades. Reptilia 1.93 with a PA MD-20, arisaka indexer, arisaka 300 on an arisaka inline m-lok mount, and an st07 in a magpul mount.
Im reloading some more 220grn subs this weekend so I can shoot this thing some more. Really fun gun, I need to put another couple hundred more rounds through it before I think I can really trust it.

The port size is not published by the manufacture and after searching for a few minutes, I cant find anyone whos dropped a gauge pin in the 8". The older 8.5" was .096", I wouldn't be surprised if this one was over .100". I staked the gas block grub screw so I don't want to pull the block to check. If I end up wanting to run the lightweight carrier again in the future ill likely just pick up one of the BRT gas tubes.

Thanks Clint!
Swapped to a holosun HS503GU green circle dot on a Unity Fast mount. I haven't been shooting this thing much since ammo has gotten so spendy but ill put a mag of subs through it from time to time and it still puts a smile on my face. Super fun gun.
