I have an ARPerformance barrel that I decided to part with, since I have too many projects right now. Only one trip to the range.
Comes with crush washer and A2 flash hider 5/8x24.
(SPF at the momebt)$150 shipped to continental U.S.
From ARP website:
".310 bore, 10 twist. M4 ramps, Melonite treated for long life, black finish.
.700 contour, .750 gas block at the mid length location, 5/8-24 thread apx 1 lb 10 oz
Does not come with a bolt, firing pin or cam pin- Option to add bolt or BCG for additional cost below if in stock.
NOTICE- These barrels are now being ported large to work with the cheap surplus ammo that most seem to shoot. They are tested with Wolf, Winchester and Remington. The Cabelas MFS 2000 ammo has been known to cause problems. Make sure the gas block port is aligned with the port in the barrel.
Currently the bolts are out of stock, should have more in apx 4 weeks."
