This BSF Barrels replacement barrel is chambered in 22 ARC with a 18-inch length and a 1:7 twist rate, made for semi-auto AR-15 rifles. 22 ARC pushes high-BC .22-caliber bullets from the AR-15 platform, which makes it a popular choice for long-range target and varmint rifles. It is a straightforward way to build a new upper or rebarrel an existing AR-15 in this chambering.
