SILENCERCO, LLC Sparrow Silencer Adapter With Thread Protector .5-28 TPI For Standard .22 Handgun/Rifle
Stainless steel adapter comes with standard .5x28 threads for use with 22 Sparrow or other .22LR suppressor. O-ring engagement keeps the muzzle threads clean and your suppressor from loosening while firing. Comes with thread protector, also with O-ring engagement.

Very slightly smaller diameter than the barrel (the reason for 4 stars), which is strange because the SilencerCo "thread spacer" is exactly the right diameter, but I wanted the O-Ring engagement and this is the best way to get it. Still a very clean look for the Rifle.

After buying a Savage Mark II with factory threads, I quickly found that my Silencerco Sparrow SS did not seat correctly. The O-ring engaged a little early leaving a 1/16th inch gap when installed on that gun. This adapter was an easy and inexpensive fix. This product is top quality, installed easily, and quickly solved my problem. I highly recommend any Silencerco product as my experience with the company has been nothing short of outstanding.
