I have been very happy with all the products from AT3. This barrel is no exception. Fit and finish is flawless.

Awesome barrel, perfect price

Ballistic Advantage is one of the best barrels on the market. Not only are they incredibly accurate but they are available for a price anyone can afford. AT3’s offered this barrel for the best price on the entire interwebs. The order was processed and shipped within 24 hours and it delivered just a few days later. It was packaged extremely well and installation was quick and easy. I look forward to buying more from AT3 Tactical and from Ballistic Advantage.
