1/2x28 FEMALE TO 1/2x20 MALE THREAD ADAPTER WITH THREAD PROTECTOR

If you have some .22 firearms that are factory threaded 1/2 x 28 male, this adapter will allow you to muzzle accessories and suppressors that are threaded 1/2-20. 

The adapters are knurled on the OD for easy on and off threading. They are hot salt blued steel and are manufactured to exacting tolerances on CNC turning centers in one operation to insure exact alignment of the OD and ID threads.  A thread adapter is also included with the adapter to keep your threads in good shape when no using your suppressor.  Get the most use out of your suppressors with our adapter!

We want to make sure that you get the correct adapter.  Please verify that you want 1/2-28 female to 1/2-20 male.  This will take a firearm that is threaded 1/2-28 and convert it to 1/2-20 for use with 1/2-20 suppressors and accessories.  Most USA suppressors and accessories are 1/2-28 so if you have a firearm that is threaded 1/2-20 and you want to convert it to 1/2-28, then you do not want this adapter.  You would instead us part # 00243.  If you have a suppressor that is 1/2-20 and you want to use it on a firearm that is threaded 1/2-28, then this is the adapter that you want.
