A manual I found on line (Building the M11/9 mentioned the installation of a barrel using leather or a soft metal like aluminum between a vise and the barrel (page 77, mid-page).Īfter reading root’s 11-22-2013 reply on the “How to remove a MAC-10 barrel” thread (he used two 1x4 wood blocks), I decided to use two scrap pieces of 2x4’s. In my research, I found that several people on this site also had the same idea. I thought, what about doing the opposite? Hold the end of the barrel between two softer materials in a vise and spin off the upper? The flats on the trunnion would be perfect for a crescent (adjustable) wrench. The use of the barrel tools involved putting the upper in a vise. piratesover40 suggested this in his 12-14-2008 reply to the “Barrel Removal” thread: It seemed like a good idea and I kept it in mind.Īnother idea is to use a strap wrench to unscrew the barrel. I could have made thinner jam nuts by cutting them in half (and using the uncut sides as the binding surfaces) as suggested by UZI SBR AWC in his 3-29-2010 reply to the “HOW DO I TAKE OUT THE BARREL?” thread: Steve B in his 1-25-2012 reply to the “Barrel removal?” thread: and Garrett in his excellent 6-5-2009 reply to the “M-11 barrel removal” thread: The thinnest jam nuts I could find were still too thick for the thread length. Machinegun has a good video on youtube:Īlthough I like to use the right tool for the job, I thought I might look at a pair of 5/8x11 jam nuts as an alternative method. Thankfully, barrel tools can be purchased from Practical Solutions or U.S. I tried finding an armorer’s manual on this site and on the internet, but I was unsuccessful. However, the barrel must have been designed to be installed and removed in some non-destructive way. Another solution is obvious: A pair of vise grips and some brute force. Since the stock barrel does not have wrench flats, I thought one solution would involve some grinding and work with a file to make some. Please read through this entire post before attempting. This required the removal of the stock barrel. 380 barrel that allows all the components to be attached. Several weeks ago, I received my M11/380 MacAdapter kit from In Lead We Trust.
