5 of 5 Colt/Umarex 1911-22LR 1/2x28 Stainless Thread Adap July 7, 2025
Reviewer: Phil from Baughman  
This Colt / Umarex 1911-22LR 1/2x28 Stainless Thread Adapter worked flawlessly in my Rail Gun!  I own a Yankee Hill Machine R-45 suppressor, and have now fired over 150 rounds on two occasions.  The report with all .22 LR ammunition is very tame, and no hearing protection has been needed.  The gun is forward heavy as the suppressor adds 13 oz, but there have been no issues with cycling other than 4 rounds from bulk ammo.  I highly recommend this sturdy adapter.
