Bond Arms Barrel Features The Bond Arms Barrel is chambered in .30 Carbine and cut to a 3-inch length giving owners of compatible Bond Arms frames a longer sight radius than the shortest barrels in the lineup. The satin stainless finish offers a moderate sheen with good corrosion resistance striking a balance between a matte and fully polished surface. Because it is built to Bond Arms own barrel interchange system it swaps onto a compatible frame using the same simple process used across the platform. This makes adding a new chambering straightforward for an existing owner.

The 3-inch length offers a slightly longer sight radius than Bond Arms shortest options which can help with aim at typical distances.
