Brand new. Never fired. BRN180 SH in 300 blackout. A friend built one with exact same upper and  a c.a.t. odb supressor and that thing is movie set quiet. Went the cmmg dissent route like I wanted to originally and almost forgot I had this in the safe. Bought new right at 950 from Brownells and never even mounted to a lower. Adjustable gas block for suppressed, unsupressed and bolt action mode which is kinda cool. Newer generation out now so I gotta take a small hit on it. This is the gen 2 version.REDACTED
