ToopMount 20mm Picatinny Rail Mount Adapter, Claw Scope Mount Base, 0.79" Rail with Allen Wrench for Outdoor Sports

Fits the real HK MP5 and the clone AP5. Also the new HK MP5 in 22LR. May not fit the copies in 22lr. by GSG etc ?

It took me a few minutes to figure out that on one side the screws must be removed completely. The other side just loosend as much as possible. Fits tightly, centered fairly easily and appears to be sturdy enough for light to medium use. Would I go to war with it? Lets hope we dont need to find out. Impressed and would recommend.

I normally don't add airsfot parts to my guns because that's a recipe for disaster but given the lack of recoil from the mp5 22lr (the ap5 2011 version) I decided it would be worth the try. Easy install, and holding so far.

This mount attached very well to my rifle (Umarex MP5 22), but the extended portion of the rail was bent which is where I mounted my optic. I realized it was bent when I couldn't zero the optic with my lazer bore sight tool installed. So I had to turn mount around to mount it (not on the overhang portion which is where I wanted to mount it). So now with the optic farther forward than I wanted I went to the range and the mount stayed in place after 250 rds thru the rifle so I guess it's a pretty decent mount minus the bent issue. I definitely will be replacing it though. Not too happy with it overall.

I bought this mount because it claimed to fit an HK-91, but unfortunately, it doesn’t fit properly at all. The alignment is off, and I’m honestly afraid to use my rifle with it attached. It feels unstable, like the scope could come loose or even fall off if I actually fired with it. I’m also worried it might scratch the finish on my gun. Overall, I’m really disappointed with this product and wouldn’t recommend it for anyone with an HK 91—it’s just not safe or reliable enough.

Screws are too weak and can be easily broken when gently installing the mount Mount also doesn't fit and stays unaligned Waste of money

Not worth trying to make it fit. It's feels sturdy enough so if you have the firearm it actually goes to then it's a 5 star from me.

Fits nicely on firearm however every accessory I attach to it is loose. It's like the rail is a little to skinny. The accessories fit all my other rails fine. This may depend on the accessory but unfortunately it didn't work for me.

Doesn’t fit my rifle; return

I was looking for Picatinny rail riser. This can only be used on very specific units so I could not use it
