Mfg Item #: RRL-ACR EC-MP5K
The Revolutionary Roller Locks MP5K ACR adaptor is designed for mounting an ACR stock or brace on the HK MP5K series of firearms. Installation 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.
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.
Installs the same as the factory backplate using existing hardware. Comes with buffer already installed.
*NOTE: This adaptor will work on the HK SP5K but requires modification of the existing buffer. Modification will be performed by our gunsmiths at no additional cost so please let us know if you need this service performed.
