The RRL MP5 ACR adapter is designed for mounting an ACR stock or brace on the HK MP5 series of firearms and clones. Use of the ACR stock dramatically improves user capability by providing a folding, height adjustable and length-of-pull adjustable alternative to traditional options. This setup is ideal for shooters and professionals who desire a positive cheek weld while using modern optics on their reliable platform.
New Feature! Our MP5 ACR adapter now features a Magpul sling loop on the left side for attachment of your preferred sling.
This part is manufactured from Nylon using a process called Multi Jet Fusion or MJF. The parts are then dyed and shotpeened for a strength and finish that is comparable to injection molded nylon. The part is black throughout.
This adapter installs the same as the factory endcap using existing hardware. To make it even easier we’ve also already installed the Choate buffer so you’re ready to hit the range as soon as you receive it.

Purched a Acr stock adapter for the MP5…shipping was fast, the adapter Installed easily good snug fit for the hinge pin,stock folds freely and fit securely onto the MP5 receiver. I was pleased to see it came with the sling loop already installed did not have to use the one on my ACR original stock adapter. Nice light weight construction but very sturdy.
