Noveske 18” SPR 5.56 barrel with gas system and PA hypertap perfect for crypto/atrs

I have a low round count Noveske SPR 18” barrel with a pa hypertap .308 cal brake and Noveske gas system. There’s a bit of spray paint in the gas tube, and a bit of copper build up on the brake (it came off another rifle. The barrel has a super clean bore and great rifling. 

Looking to get $900 cash, or trade for a nice 20” barrel, weapon light setup, etc
