    Great barrel for the price. Got about 100 rounds out of it so far, with no problems. I'd buy another barrel from them again.

    Great product.

    While I have not been able to shot the rifle yet to test accuracy. The barrel to receiver fit was perfect the barrel looks good as well as the rifling and I was not able to find any issue with it as of yet.

    Sweet as!

    Waited until I got back from the range today to write this review. Very pleased with this barrel, both in quality of machining and finish. Fit my Aero Precision upper beautifully, and the Superlative Arms adjustable gas block was a nice tight fit. Ran a hundred rounds through out to 100 yds; nice tight groups. Next outing will be to 300 yd range. Very satisfied with this purchase and with the quick delivery!

    The value line of barrels are a great barrels for the cost. The Melonite finish & fit of these barrels are top notch. It you are looking for a low cost barrel that is high quality I would recommend this product. I have used several of these barrels in different lengths and have not been disappointed yet.

    Awesome barrel for a Benjamin

    Posted by John on May 26, 2018

    Got this barrel on sale last Christmas for around $100 including shipping. It's awesome. Finish is superb and initial function and sighting-in shows it to be extremely accurate.
