This is our double threaded barrel. The standard threading is still present but the barrel also has a second set of threads making it more versatile. We make sure there is a good register for the suppressor/barrel accessory so there is no chance of shooting it out. The price shown includes the barrel. We do offer barrel threading on your own barrel for $85.00 for most threads.
Threading will be as listed below:
M10/45 – Standard threads of 7/8-9 and double threads of 5/8-24 or .578-28.
M10/9 – Standard threads of 3/4-10 and double thread of 1/2-28.
M11/9 – Standard threads of 3/4-10 and double thread of 1/2-28.
These are custom made, so please allow at least 2 weeks for the order to ship.
NOTE: You cannot thread a standard 380 barrel for 1/2 X 28 threads as the diameter is too small. The upper receiver or the thread protector are not included.
