Our Craftmanship Guarantee

We are so confident in the craftmanship of our barrels, if our barrel doesn’t outshoot your similar priced barrel, send it back for a full refund. While most companies strive for faster production time to cut cost, we strive only for quality. Our barrels are made the old-fashioned way by True Barrel Artisans™. Every barrel is carefully chambered & crowned by hand. We have a few secrets up our sleeves that no CNC machine can reproduce. There are no shortcuts with our barrels, period.

We will go toe to toe with anyone and win.
