    This barrel, and the associated gas block are a great offering to someone doing a 300 Blackout SBR or pistol build. Very helpful pin and gas block combination. The components are high quality; my 8″ SBR turned out beautifully.

  2. Chris C. (verified owner)

    a very nice barrel and nice work on the gas block assembly.

  3. Jamie Jones (verified owner)

    Great craftmanship on this barrel. This barrel is better than expect. Packaged well and quality looks as good as many other top tier barrels I have purchaed previously. Also, it shoots well and the pinning of the gas block is perfect. Very impressed! From a veteran to a veteran thanks!
