Outstanding value and quality!


Bought this for my first build,Outstanding piece of Equiptment. Came competely wrapped with a plastic mesh sleeve and good rubber caps on both ends.Shrank my 200 yd group down to 3 inches on my first range trip. Also comes with a dimple for the gas block set screws

Great buy!


Absolutely the best barrel for the price bar none! My 1st build using this barrel and shoots sub moa right out of the gate. 1/2" groups at 100 yards is common. This makes me look like an old pro at the range.

Spend your money on another company!!

The barrel is out of spec at the gas port. Ive put 3 gas blocks on, all 3 slide right on easy as can be, which doesnt seal the port and the rifle will not cycle. Blocks used: Expo, YHM and Seekins Precision. Now I have a $100 barrel that isnt usable.

1/2 moa for me

very very happy with this barrel. I am shooting 75 grain Hornady BTHP and it is shooting 1/2 moa all the way out to 700 yards. this barrel is the real deal and a complete steal at the price.

Great value!


With a cheap ass crap scope , and mediocre trigger I got right at exactly 1moa. I’m not a good shot either. That was with a bipod only , no bag in the rear. For the money I don’t think you can beat this. The gas block journal on my barrel is ever so slightly undersized, is it a deal breaker? No

Looks good, works great

Great value. Hard to go wrong with a Wylde barrel. Great finish and functionality.
