Great stock and its the best of the best!

By far the best afterma Option out there! Solid, smooth, and almost zero footprint!

I ordered this stock for my AP5-P. I was a little concerned after reading some of the reviews that it may not fit as well as it might on an MP5-K. I opened the box and was really impressed with the quality. Within minutes I had the stock installed, which fits and works very well. This is a perfect addition to my new SBR.

Bought one for the SP5 and loved it so much I decided to get one for the SP5K also. Very solid and I like the 5 position adjustments. It is a bit shorter than the H&K foldable stock at full length. It’s not cheap and the price just went up too to over $500+.

Great brace. Fits perfect, Very well made and a great addition to my SP5K-PDW

Great stock that’s pretty light weight, solid and compact. But I have 3 criticisms. First is obviously the price. Seeing how everything Hk is expensive and B&T is no exception, it’s okay with me. Second is that I think there should be a thin plastic piece on the back side of the rails to protect the receiver from any potential marring. Lastly and most important, they should really redesign the locking mechanism to put the cutouts on the bottom of the rails instead of where you rest your cheek. It’s not a very comfortable stock, but I guess you’re trading comfort for conceal-ability.

Finally found the "missing" piece of the ideal Mp5K... That is to get rid of that silly "fold-over" stock from Choate and put something on that retracts like my original A3 stock for the Mp5 does. I almost modified the K to allow for a retractable stock to fit... Wow that would have been a mistake! This BT stock works as well, if not better than the HK original Mp5 retractable stock. It is smoother and quicker. A great addition to a beautiful weapon

Haven't put it on yet due to reasons....but wow the quality is too notch. The way I could be more satisfied is of b&t sent a sticker. But it's all good!

Great product exceeded expectations

Excellent quality all around. Solid connection to mp5k with no wobble. Minus 1 star because there is no relief cut into the back plate for the hammer strut. Had to shorten hammer strut to accept stock and to keep strut from impacting the end cap. Without this mod, charging handle binds at last 1/3 of pull. Kind of lame to have to make mods for such an expensive stock to fit. B and T should cut a relief into the end cap for the hammer strut...LIKE EVERY OTHER K END CAP ON THE MARKET. Or HK should have not modified their SP5K????
