Walther 10 Round HK 416/G36/Colt M4 .22LR Magazine - Black

The ten round magazine fit tight and did not drop free when the mag release was depressed. I had a struggle removing the mag and had to separate the lower from the upper receiver to remove the mag. I discovered the top inside cap screw that holds the two halves of the mag together was proud of the molded case and was impacting the aluminum mag well in the receiver. I removed the screw and ground off about 1/16" of the exposed threads and the mag works well now. The same condition existed on both 10 round magazines. This was an issue for my Colt/Walther/Umarex M4 OPS and may not affect other firearms.

Received the magazine in a timely fashion. The magazine fits my Colt .22 M-16 perfectly. The magazine appears to be well built. A function test of the magazine revealed smooth cycling and flawless operation.

HKParts delivered parts very timely and was VERY responsive to my questions - I'd give HKParts 5 stars! However, if you are purchasing this for magazine to be used on the Colt M4-22, beware. I had to modify all 4 of the magazines purchased as there was a screw that was too long and would block the magazine from fully engaging. In the end the modification was relatively simple (just removed some of the screw length) ... I spoke with HK-USA and Walther and both were not particularly helpful or even acknowledged that there was a problem with the design or manufacturing. In my opinion, it would be a really easy fix at the manufacturing stage - just use a shorter screw.

Great mag, matching color and fit. Well Made.

Cute little mag. Wish I paid attention to the fact it?s Charcoal gray and not black..

The quality is evident in the build of this mag. Fast shipping and good price. Thank you!

Product arrived on time and works perfectly, thank you!
