HK/Umarex 416, Colt & MP5 .22 Barrel Adapter

Our Products - Heckler & Koch Firearms > Umarex

HK/Umarex 416, Colt M4 or MP5-A5 .22 Barrel Adapter

This custom adapter allows you to remove the stock (OEM) flash hider and 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 one & only adapter made for the Umarex HK 416 & 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 only available here at HKParts.net. Please note: You will need to use your existing o-ring from the factory flash hider. All other parts are included with the adapter.

Comments and Suggestions: Fast shipping and great product. The quality is excellent. A "must have" if a threaded barrel is needed for your Colt AR15-22cal.

Comments and Suggestions: 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.

Comments and Suggestions: Excellent 1/2 x 28 adapter for Umarex HK416D .22LR; once installed, it blends in with the barrel and is very difficult to detect its even there. Simply unscrew original-supplied flash suppressor, install adapter, and then install a regular flash suppressor of your choice with 1/2 x 28 threads. I installed a small O-ring on adapter end to make it easy to remove the (now) regular flash suppressor by hand; when at the range when I want to install my TAC 65 .22LR Suppressor.
