I have a couple of uppers that I don't need/have duplicates of.
First is a 25-45. It has a Black Hole Weaponry heavy profile barrel that is 18 inches long, black nitride coated. Gas block is .750, mid length gas. Upper is a slick side, no dust cover or forward assist. Bird cage flash hider. Has a 15 inch ultra slim free float handguard. Price is $175 shipped, without bcg or charge handle. $250 with bcg and charge handle. This one is new, I have never fired it. I put 2 together, and like the other one better. It's stainless and lighter profile. Sold! Payment received, ships tomorrow.
Second one is a Wildcat. It is the 30 American, or 30x42. Use 6.8 SPC brass and size it in 30 Herrett dies. Barrel is a Black Hole Weaponry as well, 16 inch nitride, mid length gas, 15 inch M-lok free float handguard. Heavy profile as well. Upper has dust cover and FA. BCG and charge handle included. Never fired, I built 2 and like the stainless better. This one is $325 shipped. Pictures available, I am too old and slow to figure out how to post them here.
