WarBlock Builder

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

Please add special instruction i.e. “Please remove gas block after pinning so I can install my rail” in order notes at checkout.

Some browsers may misbehave with the builder, if you are having trouble, please first try another browser.

Your WarBlock barrel assembly will then be expertly aligned, pinned using MIL-STD 2/0 taper pins, and your selected options assembled. Or in the case of a low profile gas block, set screws will be Rocksetted in. 

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

We also use and can supply Aero Precision, and CMMG barrels upon request.

Please Note: March 22, 2019. We are currently upgrading our CNC machine and as such are experiencing significant delays for both pinning services as well as WarBlock availability. Sorry but we will back up a running as soon as possible and faster than ever. Thank you for your patience!
