I built this gun with primarily Geissele parts for the whole 50 Shades of FDE from a Geissele receiver set. The gun runs great, I just need to thin out the herd a bit. 14.5 Geissele CHF barrel has literally had 2 boxes of ammo through it to dial in a scope that was on the gun. I've got around 1700 in the gun so price is firm. The gun DOES have an adjustable gas block for running suppressed or without. You will need to dial it to your preference. Its a Q agb that you can adjust without removing the hand guard.
Rifle located in Clear Lake area but I can meet in the Houston area to make a sale.
