Question: Will rhis fit a SW k22 with a 6unch barrel?
Document: Received this and it looks nice. Does not fit my GSG-522 at all. My gun has several metal parts on top of the barrel that are under the Picatinny mount that interfere with the mounting. You have to take the Picatinny rail off to mount this. Make sure your gun does not have these before ordering.
This is a great product. Perfect fit on GSG 5. Very easy to sight in. 100% satisfied with this product!
This is not a great product. The light, visibility and durability are very average. Not bad for the money but definitely not worth putting on your .22 in my opinion. Kept rattling off and didn't fit well.
1- for quality and durability. After one mag of CCI stingers it broke.1- it don't fit GSG-5's well at all and the optic is too small to use as a shoot through.
Perfect fit on my MP5 A5 .22 scratched the surface of my rifle but not too noticable battery dies quickly just remember to put it on &#34;0&#34; to switch it off
No modifications required just perfect fit! At first I was hesitant to order because of the reviews that it will not fit, but I gambled anyways and it's just what I was looking for. Just perfect and good price!
At first I was a little hesitant to purchase a $30 red dot sight, but after a 10-15 minutes at the range, I easily sighted it in! It was a tight fit on my H&K MP5 A4 22LR, but works flawlessly for a $30 sight!
I ordered this sight because I read that it does fit the HK MP5 A5 .22LR without modification. That is definitely not the case. The unit it self looks like it works great, but I am not going to modify my gun to make it fit. I will be sending it back.
This mount fit perfectly on my Umarex MP5SD22. Initially I had purchased a claw rail mount made by UTG, but it did not fit the Umarex ($20 down the tubes). This all-in-one solution is simple and effective. I have fired 300 or so rounds with this in place and have not had any problems. Zeroing is straightforward if you have a bore sight laser and it holds zero. It is a good value if you need a simple Red Dot.
Basically, the bottom back of the sight sits in a slot on top of the receiver to keep it from shifting forward/backward once its installed. It's a nice setup. However, my sight had a very tight fit in that upper receiver slot. I could have filed down the inside edge of the slot on the receiver, but I just installed the left side claws and screwed them down to get the sight level and snug. Not ideal, but it worked.
Answer: no
