Guys (and girls and purple penguins) let me be perfectly clear, this is totally NOT a stock. It doesn't even look like a stock! What kind of stock costs nearly 500 dollars? EXACTLY! I'm 8'11 with a 10 foot wingspan, so the telescoping feature really helps to accommodate my rather lengthy wrists. When I want to brandish my SP5s akimbo at the gun range to impress the lady working behind the counter with pinpoint sub-MOA accuracy, I look ONLY to my B&T braces! Fantastic! A+

Perfect fit for my new SP5. No Adjustments necessary. Tailhook Mod1C brace also slipped on easily. Would buy it again.

I was impressed with the fit and finish of my brace mount. It fit right on to my new H&K SP5. I attached a Tailhook arm brace and the entire setup only took minutes and works smoothly. I very much like my B&T brace mount. It does not rub on the receiver at all and is very stable. I hope that B&T will offer a butt plate to attach to this for those who get their paperwork approved which would allow converting an arm brace to a conventional, telescopic stock.

Great design and solid brace, the sliding rails could be smoother like on the APC9. Overall love the look and feel of the brace. Over engineered like everything from Swiss and German :) Picture on my SP5: https://imgur.com/5PM1zzj

This is a very high quality product

Fits the SP5 absolutely perfectly right out of the box. Ingenious design for the collapsing rails ensures you won't get any scratches or wear in the channels of your receiver unlike other collapsing braces with MAJOR fitment issues. I learned that the hard way. I wish this was released sooner!

Very nice Brace. fitment is excellent!! did notice some plastic flashing on the back cap assembly . but overall I'm very pleased with it. Also the side rails do not rub the receiver at all which is a plus !! I plan to purchase 2 more when funds allow.

Ordered this brace for my PTR 9 pistol, HK MP5 clone. It fit my gun perfectly with no modifications. It is high quality and looks and works great on my gun.

Best product IMO very well built. Quality is worth the price. Great job on the product.
