  1. arrival of new barrel 4 Star Review

    Posted by on 21st Feb 2017

    i gave this product a 4 and the reason i did i have not installed it on a rifle yet it came wrapped up and boxed in a very nice package i removed the barrel out of box for inspection it was a perfect finish on the barrel cleaned the barrel out and coated with lite lube for a future rifle build , if it shoots half as good as it looked inside and out it will be a good barrel very pleased with the looks of it, but what can i say these people have been building rifle barrels for a long time they are very well known for building superb rifle barrels.


  2. James from Ga. 4 Star Review

    The barrel arrived quickly and was packaged well I am not the greatest shot but on a good day I can put 5 shots inside 1 1/2 at 100 yards. This is outstanding for me !! And I have only shot 55 grain ammo. Can't wait to try a 69 or 77 grain. Great product guys !!


  3. First Barrel was Defective; Second Barrel was Great! 4 Star Review

    Posted by on 16th Jan 2017

    Purchased the GM-20 for a carry varmint rifle, but I couldn't even hold 2-inches at 100 yards despite using 6 different bullet weights and 17 different loads. I called GM and talked with Morgan Shaw and he asked me to return the barrel for inspection. Turns out there was a burr on the gas port that blew out the accuracy, so GM promptly sent me a new barrel that arrived within a couple of days. I put the upper back together and went to the range to get it sighted in using a couple of standard loads I have for a different varmint upper. The new GM-20 barreled upper promptly shot 0.470" and 0.411" using a 60 gr and 55 gr bullet respectively. I sure didn't like having a defective barrel at first, but GM was totally professional in correcting the problem. I can recommend the GM-20 barrel as a very accurate medium-weight barrel and I can recommend GM based on their service before, during and after the sale. It turns out that this barrel is a great fit for my needs; it will be for you too.


  4. Top of the line. 5 Star Review

    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.


  5. 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.
