    These are great for building 22 custom barrels

  2. Needed a lot of work 3 Star Review

    GM barrels have bin my go to for menu years now. As a gunsmith I loved these barrels and Covid killed them. Every gunsmith barrel I ever gotten from them was spot on with no problem at all. This 22cal heavy 1ā€ barrel was so out of Centric it was ridiculous. I have never had to do so many Passes on the lathe to true one of these barrels up. As I said it was a 1ā€ barrel to start and it is now a .970 barrel. Not what Iā€™m used to from GM.

  3. decent barrel for a dedicated AR upper project 3 Star Review

    The blank was a little off center on one end, about .050ā€. At the price, well worth some turning between centers to true with the bore !

  5. 1st Rate quality, great pricing 5 Star Review

    Easy turning, no warping, finished barrels shoot very well. Better than I can shoot! I'm manufacturing TC Contender 16 inch carbine barrels with a threaded muzzle and 11 degree crown. Barrel lug welds clean and sweet to this alloy, blues up nicely with Brownell's OXPHO cold blue. Even get a bit of that handsome deep purple/blue color, probably due to the high quality of the alloy and consistent annealed state they come in. Using PO Ackley's barrel turning tool design on centers, save a lot of effort not having to use a follow rest. .035 passes on 16 + inches, without chatter or heavy tool marks. Again the quality of the alloy and heat treatment. Chromemoly's are the toughest alloys to get a fine finish on. GMRB's alloy is an exception. Turns like fully annealed W2 water hardening tool steel.
    Couldn't ask for a better barrel blanks to turn.
