HK/Walther/Colt .22LR Threaded Barrel Adapter - Converts 8x.75 To 1/2x28

This custom adapter allows you to easily convert your .22LR barrel from 8x.75 to 1/2x28 threads. It replaces the stock flash hider and provides a secure, permanent mounting option with no loss of zero. Each adapter comes with a fitted thread protector to safeguard the 1/2x28 threads when not in use, a new Red O-ring, and a built in wrench slot for convenience.

Specifications:

• Converts .22LR Barrel From 8x.75 To 1/2x28

Compatible With:

• HK 416 .22
• HK MP5/MP5K .22
• Colt M4
• .22 LR Firearms Threaded 8x.75
• Other Walther/HK/Umarex applications

Please Note: This is not for use with the GSG5, as the GSG5 models have 1/4x28 threads. If you have a newer model of the 416 .22LR, your threads may already be a 1/2x28, so you will not need this part.

Technical Note: The O-ring on the adapter takes a lot of wear as you screw and unscrew different devices, we highly recommend purchasing spare O-rings for it - These are located in the related products section below. HK, Walther, Colt, .22LR Barrel Adapter O-Ring
