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

SKU: HKP-01845
Brand: USA

HK, Walther, Umarex 416, Colt M4 or MP5-A5 .22 Barrel Adapter With Thread Protector - M8 X.75 to 1/2 X 28

The finest thread adapter available that converts the factory thread pitch to 1/2 X28. Each adapter comes with a new O-ring (red) & built in wrench slot. This custom adapter allows you to simply unscrew the stock flash hider and quickly and effortlessly convert the barrel to 1/2X28 threads. This adapter can be mounted permanently & provides the perfect index without any loss or deviation of zero.This is the lowest profile and factory correct mount that you can get.

This is the one & only adapter made for the Umarex HK 416D & Colt M4 & MP5-A5 .22 style rifles. Each adapter comes with a fitted thread protector for protecting the exposed 1/2 X 28 thread when a flash hider, comp or suppressor is not in use. This is a must have for those that want to use a sound suppressor or other muzzle device. This part is made in the US and is only available here at HKParts.net.

Fits all of the following:
  • HK 416 .22 LR Rifles & Pistols
  • Colt M4 .22 LR Rifles
  • HK MP5 .22 LR Rifles
  • Other Walther/HK/Umarex applications

Note:Not for use with the GSG-5 as the GSG5 models have 1/4 X 28 threads

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 found in the related products section below.

"Hk 22lr Umarex"

Jude Girtz on 2/23/2012 9:40:09 AMVerified

Overall Product Rating:


I purchased this to install on my Umarex HK 22lr. I did this to get rid of the fake suppressor. The fake suppressor made the gun too front end heavy. It works great.
