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 ?

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.

Does not fit AP5/MP5 clones. Could be fine for airsoft but seems to flimsy for a real gun.

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.

Item "fits" but backwards only so the longer portion of the rail is forward on a MP5 22lr. It gets in the way of the charging handle and putting it on that way will probably lead to you cutting your hand when pulling back on the charging handle. The non-airsoft one that costs like $100 has it so the longer portion of the rail more toward the stock. So it got returned. So the person who said it didn't fit without dremel work was correct if you want it fit in the "correct" direction.

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.
