The quality of GM barrels are assured. Never had a average or bad barrel, all have been superb. Better yet customer service is equal in quality. These barrels will compete with any barrel out there. Thanks GM! I'll keep coming back.

Barell arrived even earlier than expected. Received great insight and help from the folks at Green Mountain when ordering over the phone. At my gunsmith now being threaded and chambered for a rolling block action in 45-70.

Beautiful barrel - bore is impeccable and I'm sure it will shoot accurately. Can't wait to mate it to my 1885 receiver.
