HKP HK UMP/USC (.40 S&W/.45 ACP/9mm) 4 Piece Picatinny Rail Set

Just what I wanted. Fits perfectly with screws provided

This set came with every thing needed to install. The installation was easy and is perfect if you want to add optics.

High quality picatinny rails and mounting hardware for USC H&K .45; perfectly aligns to all four pre-tapped stock mounting bases; and numerically marked rail slots facilitate rapid placement of accessories. Integrates use of lower rail hand-stop / sling attachment (must use existing longer allen screw). Greatly enhances overall appearance of USC.

I just wanted to leave a review for the product SKU: HKP-17429 4 piece picatinny rail set. I have mounted all 4 rails on my USC and am using an Aimpoint red dot sight on top and have also mounted a vertical grip on the bottom that I have also ordered from You as well. I have also a strong light I could mount if I choose to do so from Texas Wild Boars that is of a very good quality. I have taken the USC out to a 100 yard indoor range to zero and try it out. The Remington 230 gr. FMJ rounds produce the very best group putting all 5 rounds in a single hole at a 25 yard distance! It also shoots that round pretty well at 50 yards and shooting also Federal HST that groups close to them as well. Out to the 100 yard mark the Remingtons drop off quite a bit and the group spreads as well. However the Federal HSTs still hold up at 100 yards which I like so much because I can use them as self defense rounds at any distance out to 100 yards and maybe beyond that! In the meantime I will be buying more of and using the Remingtons as practice and plinker rounds at closer distance. I found all that to be quite interesting and am having a lot of fun as this is the very first pistol caliber carbine I have ever bought or owned! The Winchester rounds where not very impressive so they will be used in my Kimber 1911s. Overall this 4 piece picatinny rail set is pretty solid and I have the upmost confidence with everything that I have mounted on it so far! Also am VERY impressed with the H&K USC that I am eager to get more ammo to do more shooting with it! Thanks for such a great product!

Love this.

Everything had a perfect fit

Top shelf quality fit and finish. I?ve only used the top rail so far to attach my optic.

The rails were a perfect fit. The allen screws were great. I?ll buy again from HK parts.

This set of rails is absolutely perfect for the UPC 45 carbine. Allows for the red dot installation, and accessories on each side and bottom of the foregrip.

Very nice set of rails! Bought 2 sets, both fit perfectly.
