    Posted by on 20th May 2020

    using this barrel to build a 30-06 for 230 grain and higher weight bullets on a mauser action I have the barrel thread contoured and chambered and installed on the action with no problems it is a great barrel for the money and I am looking forward to finishing this rifle up
    God bless you for proving a great barrel at a very reasonable price

    Fantastic customer service once again!

    I needed a barrel blank in 300 BLK and Green Mountain came through with a quality barrel for the rifle I was looking to build.

    Thank you!

  3. As far as initial looks go.... 5 Star Review

    Very impressive blank for the money bought on sale. I'm planning to stub/rebarrel a BSA Martini Cadet single shot and chambered to 300 AAC and using 357 brass run into 300 sizing die requiring only minor extractor metal removal. I'm still investigating the soundness of stubbing - have stub donor barrel reserving # matched orig'l brl which is reamed to 32-20, so may down the rd have it rebored/rifled to 357mag, or maybe not if the 300 pans out and sings.

    Anyone have reservations on my basic stub barreling plan? I may add a pivoting near half round cross pin that cuts through to barrel thread root depending on donor brl thrd snugness. And add some set screw[s] thru donor into smooth GMB smooth tenon divots along with marine-tex etc.

  4. Long term user 5 Star Review

    I bought my first Green Mountain barrel at least 15 years ago and it was the best shooting barrel I had ever tried on my 10/22. Since then I have bought about a dozen barrel blanks and would do it all over again because I don't have a single complaint. All of them have shot better than what I was suspecting and they answer their phone.

  5. great replacements 5 Star Review

    I have used Green Mountain barrel blanks for many projects. Good quality metal that turned easy makes a great finish wether what your desired outcome. The accuracy of these barrels are in many cases better than a factory barrel. My project list has gotten a lot smaller due to the price and quality of these barrels.
