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

 

Note:Not for use with the GSG-5 that has 1/4 X 28 threads.
