If you have an Lage .22LR barrel insert and you want to thread on your suppressor with 1/2x28 threads then this may be the solution. This quote does include the thread adapter. We thread your barrel insert to a small thread of 8mm x .75mm and machine the adapter flush to thread up against the shoulder of your barrel. You pay return shipping to ship back your upper receiver and barrel(s). This quote does include the thread adapter. You must have a longer .22 LR barrel or there is an additional charge to remove the 9mm barrel and cut it back, please call with questions.
