Product reviews for MP5 HK33 FOLDING STOCK W/ FOUR BUTTPADS, AC-UNITY

I'm very impressed with this AC-unity stock. Very well designed. Fits just like a German A2 stock. Modern sling connections make for a slick and functional package. It is the lightest folder I have found yet is very comfortable and solid when shooting off the shoulder. Highly recommended

Works well the only issue is the button retaining the stock allows for some wobble due to being undersized. Nothing a little jb weld to build up the thickness won't fix.

Placed an order for this stock on 8/9/22 and received it in just 5 days, the stock was super easy and installed in seconds, and the butt pads are the same super-fast on/off. Now the customer service at RTG is totally awesome! Highly reccomend RTG

Excellent value. Extremely pleased. I strongly prefer it over my factory HK 93 collapsible stock for shoulder fit, comfort and stability. Plus, it can accept numerous type slings, I am currently using an AK type sling with it.

This is the best bargain going for an MP5 or Hk33. It made my rifle far more usable by shortening the LOP slightly but noticeably. I'd like to confirm this fits on the Century C93 Sporter. The variety of buttpads is a nice addition.
