  1. 1 in 14 -20" barrel 5 Star Review

    Posted by on 30th Jan 2018

    Used the barrel for a 22 long rifle conversion.
    Blocked the gas port with a 4-40 set screw. left the gas tube and buffer out of the rifle.
    Used a cmmg bolt assembly so the rifle could be switched back to 5.56 by removing the set screw and installing a gas block and tube and buffer assembly.
    The rifle shoots really well and the chrome lined barrel is very easy to clean.

  2. Best Choice 5 Star Review

    Posted by on 13th Dec 2017

    This 20" barrel with the 1:14 twist is the best choice for shooting ammo 55gr and smaller. It is also the best choice for .22 Conversions. Excellent accuracy. Excellent performance. Looks good too.

  3. 1:12 twist 20" barrel 5 Star Review

    Posted by on 28th Jan 2017

    Used this to build a parts kit into a semi-auto Nam era looking A1 rifle. 3 inch 3 shot groups at 200 yards on a 100 yard small bore target using the A1 iron sights! Win 5.56mm 55gr ammo. Love this barrel!

  4. makes a light weight upper with free float tube 4 Star Review

    Posted by on 15th Sep 2016

    The barrel arrived packaged so the UPS man would have to work at damaging it. Opened the box and workmanship was spot on. The reason for 4 stars is the description does not tell you this barrel has M4 feed ramps also the twist rate and cal are stamped on the barrel but it is under the gas tube near the chamber in the time of muti cal lowers this could be an issue. On to the good stuff head space is good with anderson bolt and the 1 in 14 twist shot PMC 55 grain ball at 100 yards 10 shot group inch and half no signs of tumble at 75 deg. this should make a nice ranch rifle . When I get 50 rounds shot I will try some hand loads i bet it will shoot under a inch.
