We currently have about 20x Non-Restricted length barrels left for the B+T GHM9 rifles. Take your currently Restricted rifle off the books asap. Cost is $550 + tax and shipping if required. Additionally we have our longer custom hand guards as well as our CZ faux suppressors to top the package off.
Current turn time to change the barrels is 2-3 days, then it's yours to keep forever. Call the shop to place your order.
