  1. Top of the line. 5 Star Review

    Posted by on 12th Jan 2017

    All GM barrels are top notch for fit,function and finish. Our 3 gunner customers love these 20" 223 Wylde barrels and they always ship in a timely matter.

  2. Great product 5 Star Review

    Posted by on 22nd Dec 2016

    I bought the GM-M20 to replace the barrel on my bushmaster. It arrived in about a week, well packaged and in perfect condition. Headspace was right on the money. After breaking in the barrel, I tried several different factory loads. The results are as follows: (All are 3 round groups from sandbags @ 100 yards)
    American Eagle 5.56 55 gr FMJ .56"
    Barnes Vor-Tx 5.56 70 gr TSX .65"
    Nosler Varmaggedon .223 62 gr FBHP .53"
    Federal .223 77 gr Sierra Matchking .51"

    I couldn't be happier.

    This is my 4th GM barrel. Can't beat them for a quality barrel. This one out shoots one of my other rifles that has an FN CHF barrel.
