  1. Excellent barrel blank 5 Star Review

    Posted by on 14th Apr 2015

    Headspace good. All internal diameters (bore, chamber and extension) are less than .0006 run-out. Chrome is uniform through out entire chamber and bore. Very nice blank at a great price.


  2. It shoots! 5 Star Review

    Barrel headspaced perfect on no and no go gauges, turned very nice when contured and shoots well. Very happy with Green Mountian and all the barrels they produce. Thanks
