Feyachi Picatinny Rail Riser Mount, 0.75"/0.83"/0.95"/1" High,3 Slots/5 Slots Riser Mount for Red Dot Sight

I bought two of these for my AR-15 to adjust the height of my red dot for a red dot magnifier. These things are solid as a rock and get two thumbs up for me. They are very secure with the screws that they use and is incredibly easy to use. The fit was perfect with little to no play and is a great value for your money. With little weight and great height just miss at small amounts makes this a great functionality for any rifle with a picatinny rail.

Works perfectly. Nice height for visibility. Looks nice .

This is a good system to ad to your rifle platform. Perfect for a red dot or to get the custom setup perfectly aligned for you. It’s easy to install and easy to set to your custom high it’s made very well . I’m going to buy a few more.

When it comes to Picatinny rail risers, this one is particularly well thought out, engineered and well made. The most obvious feature is it can be adjusted to 3 different, standard heights. That's huge! It should work for most standard installations without having to buy multiple risers. You could even have one for trial-and-error purposes to find your ideal height before purchasing something else. Beyond that it has few more unique features.It attaches to the rifle's rail via one 5mm integral crossbolt and hexnut. Personally, I exchanged the nut for a 5mm wingnut and fiber lock washer for a toolless installation. Also, on both sides of the crossbolt are spring-loaded "feet" that engage the two adjacent rail slots. This makes for a rock solid clamp to the rifle rail.The two screws that secure the rail's height adjustment have stainless washers under their heads. A nice touch, plus it prevents them from galling the aluminum part. Also, when I installed the red dot sight, the sight's mounting foot covered the screw heads, preventing them from loosening. I don't know if this was intentional, or just a lucky coincidence. Either way I'll take it.As someone who has spent many hours and many dollars experimenting (which I never expected would be necessary) to find the right rail riser that gave me the iron sight co-witness I was looking for, I really appreciate the features and quality of this particular rail riser. It's close to a one-size-fits-all solution.

Works fine as a riser for my red dot (airsoft use) and I would recommend using blue thread lock to keep your fasteners tight don't want it coming loose and your red dot falls off during airsoft skirmish!

I bought this for the use of figuring out my comfortable height for my holographic sight since it has adjustable Heights it's perfect for this then I will order accordingly but this I consider a tool to figure out height adjustment ,not to use for shooting. But I do believe it would be strong enough to actually use for shooting

Fit perfectly and aligned well

I would never use or recommend this for use for an optic for an real firearm. By it's nature it has two more failure points which can come lose than a solid riser does, held by steel bolts threaded into aluminum treads. The lugs that are made to engage your optic rail are separate pieces made of plastic and very shallow.I bought it essentially for the purpose of measure what height solid riser would work best in different scenarios, for that it was perfect. It is also rather well made and designed considering it's price. It is actually a four heigh riser not a three, as there is an unmarked setting between .83 and .1 of .91 inches. It isn't a common height and why it probably wasn't even marked. The recoil groves of the picatinny rail were very close to spec at .204 and consistent ( spec is .206 +006). I think this is in part due to the coating they used and the Geiselle mount I initially tried it with just fit. The adjustment uses two bolts and long groves which actually is very solid. If one really needed to use this mount I'd suggest finding the height and then applying some good thread locker and treating it as a solid mount from them on. The biggest I would have with using it is that the lugs that engage your optic rail are plastic and shallow, probably to help it fit the wide variety of rails from airsoft, printed, etc. This is not a hard use rail, I'd hesitate to call it even a casual use rail, and is more of a toy.
