    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.

  4. Excellent Barrels! 5 Star Review

    This is the second barrel I purchased for AR builds. Both performed very well on the range. I would not hesitate to buy another.

  5. Very accurate barrel, great groups 5 Star Review

    Used this barrel in a varmint build with a free float handguard and a 3# drop in trigger and am getting 0.544 MOA with handloads using Nosler 40 grain Varmageddon bullets and Benchmark powder with CCI 400 primers. I'm very happy with the accuracy in this highly recommended pencil profile barrel. Bought a second one tip build a retro M16A1 clone, and look forward to seeing what it'll do with drop in handguards and iron sights next.
