Question: Would it be possible to fit two of these back to back on the upper receiver of an AR-15?
Document: This a great product. Fit easy to top rail of upper plus extents the upper. Great for leveling a red dot scope to a magnifier.
Seemed to be fine, but does not fit standard pic rail length mounts. a Larue nor a Trijicon base would fit. If you are going to be using rings, then these should work fine.
Nothing to complain about. It's a nice piece for moving a scope (with limited eye relief)  back over the charging handle of my M4. Does what it says it does... nothing more, nothing less! I would recommended it. Seller was quick to ship and was packaged well.
I used this and reversed it so I can get my 4&#34; eye relief scope closer to my eye with out folding in two because of my long arms was a god send.
I used this Dovetail riser to move my NVG Scope back on my AR15. Worked well, sturdy, sighted in without issues.
bought this riser as an extension rearward for my saiga ak47,with my compact scope it didnt set back far enough for proper eye relief ,this solved my problem
was wanting too fit rifle scope to a m-14 socom. help to get eye relievief  where need  . nice stiff base . used tms ar15 m4 scope mount . both great products
This is well built, sure. But it did not fit properly onto a standard pic rail. The pin that is used to tighten down the riser caused it to sit at an angle, the front higher than the rear. On top of that, the whole thing is warped. Spend the extra money and get the Yankee Hill version...
(In my case, since I am mounting it upside down, the offset part of the mount now goes slightly below the front-stock, allowing the attachment. So my front grip was attached to the offset part of the mount, allowing a shorter arm reach to get to it.For my purpose, it works now; but it would have been easier to use a mount that has a one inch offset "height.
The company seems to be very customer friendly and eager to help you in the event of any problem. My product arrived with a friendly letter that included a phone number to call if I had any problems. I would be very comfortable shopping with this company again.This item is well made and is exactly what is advertised. I am very pleased with it, and am confident in its quality. I give it 5 stars- hands down.
Answer: yes
