JC's Review of Magpul Industries SL Grip Modules & HK Polymer Trigger Housings
This is the best upgrade you can do for your MP5 or similar roller delayed blowback clone. This will only work with an SEF trigger pack. I bought one for a K model and I should have went ahead and bought another ESK for my full size MP5 clone. I will be ordering a second one in the future. Also, you can have the option of adding a second long length, shorth length or blanking off the right aide selector switch on your trigger pack. All of which are included in the package.
