    The 11.5 pencil barrel was perfect for my Colt 733 clone build! Fantastic product with fast shipping.

    I hold this barrel in the same regards as DD. Have both and both are great. Used for a 733 clone.


  3. Great affordable barrel 5 Star Review

    Posted by on 18th Sep 2019

    I was looking for an affordable lightweight chrome line 11.5” barrel and my search ended with Green Mountain. Fit & finish were superb. Zero’d my SBR with an Aimpoint T1 at 50 yards with Wolf Gold and had a nice 1” group. It’s not match grade ammo but I was very satisfied with the results since I’m not running any magnification. No problem ringing steel at 100+ yards. Highly recommend this barrel!
