  5. Superb, that is why I bought 3 more! 5 Star Review

    Posted by on 27th Mar 2018

    I purchased one of these barrels a couple of years ago. It was going to be a "plinker." It turned out to be so accurate that I ended up building a light weight match rifle from it. Last year when these barrels were on sale I though I would get another one just to have on hand when a project came up. I waited too long and they went off sale :-(

    For 6 months or so I checked the web site every morning until I found the barrels on sale again. I purchased 3. Not sure what I will build with them but it is better to have and not need than need and not have :-)

    Bottom line an excellent barrel with I would buy again, and did!

    p.s. I do wish they had been available with M4 extensions. True the M4 cuts are not really needed on a rifle length barrel. Problem is that so many upper receivers these days have the M4 ramps.
