Welcome to the WarBlock Builder! Simply choose your base barrel configuration, then add the options you want and click add to cart.

Your WarBlock barrel assembly will then be expertly aligned, pinned using MIL-STD 2/0 taper pins, and your selected options assembled.

*Because we don’t know what your barrel looks like, images of the Customer Supplied Barrel option are generic and may not appear true to life. Pinning and assembly charge of CSB is $35. Yes we can do nitrided/melonited barrels.
