HK, Walther, Colt, .22LR 1/2 X 28 Barrel Adapter

Barrel Adapter With Thread Protector M8 X.75 To 1/2 X 28

This custom adapter allows you to unscrew the stock flash hider and quickly and effortlessly convert the barrel to 1/2X28 threads. It can be mounted permanently and provides the perfect index without any loss or deviation of zero. Each adapter includes a fitted thread protector for protecting the exposed 1/2 X 28 thread when a flash hider, comp, or suppressor is not in use. It also includes a new O-ring (red) and a built-in wrench slot.

Compatible with:

• HK 416 .22 LR Rifles & Pistols
• Colt M4 .22 LR Rifles
• HK MP5 .22 LR Rifles
• Other Walther/HK/Umarex applications

Please note: This is not for use with the GSG-5, as the GSG5 models have 1/4 X 28 threads. If you have a newer model of the 416 .22LR, your threads may already be a 1/2 x 28, 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
