This is probably the best stock you can buy for the MP5. It’s just as comfortable as the A2, but folds up. It also cost less than half what an A3 cost and is much lighter. I have this, the HK A2 fixed stock and the HK A3 3 position. If I could only have one it would be the B&T folder. Get all three if you can, but start with this one.

Bought this to replace an A2 stock that came on my PTR9. The A2 stock had lots of wiggle and wasn’t great. This has a super tight lockup with zero wiggle. Immediately took it to the range and ran 3 mags through it without issue. Definitely would recommend to those that want to keep good ergonomics while maintaining the ability to collapse the gun down.

Very happy with the stock. Snug fit on my PTR 9CT. Lock up is nice and tight with no wiggle. Release button is firm but not too hard to press. In the folded position the stock does not lock but the hinge is stiff enough that it will not open unintentionally. The stock seems a little thinner than the fixed A2 stock, which to me is an improvement, as I more naturally get my eye behind the rear sight.

I just feels quality right out of the box. Nice and tight, absolutely no wobble on the stock or the endcap. It fit perfect on my PTR9, emulating the A2 stock exactly.

B&T Parts.com had the best price. Way less than others. This is a super high quality stock. Fits perfectly on the HK SP5. Button is easy to depress and easy to close or open. Nothing is locking it in the closed position - which is fine. The polymer and components feel higher quality than my magpul folding stock for my AK. Cheek weld is great for iron sights. Length of pull is perfect (not too short/or too long). Very happy with this purchase. Swiss made is hard to beat.

If you are looking at this you know it's what you want. It fits great and feels like an A2 with added benefit of it being foldable. Plus this is the best price on the internet on this,

Good fit and good pricing (beats prices from HK Parts and others).

Replaced my A3 with this stock to have a better cheekweld with my cowitness Aimpoint T2. Fits really well on the SP5.

AMAZING! Shipped quick, went on with out any issues, looks super sexxy!!! Highly suggested!

Fit and finish are excellent for MP5 and clones. Lowest price and ultra fast shipping. Highly recommend.
