Yankee Hill Machine Co Scope Riser Mount, 1/2" Rise, 5 1/4" Long, Black, Picatinny YHM-227A

I love this rai! It was so easy to install and will stabilize whatever I mount on it. Good value for the money too

Feels like a quality rail. Mounted an ACOG sight with RMR on it and now its perfectly aligned eye relief when I aim

Was a little hesitant about this product given some other reviews saying how sometimes it would be missing the installation screws or would wobble around, but I’ve had none of these issues. Went on nicely, tightened perfectly. Threw it onto my rifle and brings my scope to around 2.04”ish night. I’ve been thinking about getting a Geissele 2.04” Mount but have been cautious because I thought it might be too high. This product offered a perfect solution to try a higher mount on a budget. Fantastic product and very happy. Looks cool too. Can’t beat for only $30.

I bought this after watching a few videos on passive aiming through night vision and thought I wanted to try a high rise mount for my holosun 403b. I stumbled upon milspec mojo's channel and in one of his vids he talked about how he used this as a budget option until he got a dedicated mount for his aimpoint. I saw the priced and decided for the money it was worth purchasing just to try out a higher optic. This is well built and I saw no obvious flaws or defects when unboxing. Mounting it was smooth and easy and caused no issues. Mounting my holosun to it was just like mounting to any other rail and once I receive my magnifier I expect to have no issues there either. Once everything was mounted and I did a little dry fire practice and I immediately realized the benefits of having a higher mounted optic. It's so much more comfortable to aim while standing and resting. I dont have to crane my neck down at all keeping it completely straight. It did take a little to get used to but now I don't see myself going back to lower 1/3. I will say on my next optic I'll probably pony up the extra cost for a dedicated mount from scalar works or unity because this mount is a little heavy. Other than that I have no negatives. If you want to try out a high rise optic without spending a couple hundred bucks on mounts then this is a good place to start.

Solid riser rail! Zero shift once tightened down. Highly recommend for any build.

I have been building AR's for several years and recently wanted to see what all the hype was about with optics being mounted at higher centerlines on the rail(1.93, 2.04, 2.26). Rather than spend a couple hundred dollars on mounts, I thought I would buy a $30 riser and test out a higher mounted optic. With a 1.55 1/3 co witness mount and this riser, the optic sits at 2.05 and initially, I really like this height and will know better after using. The mount is very stable and the quality is excellent. I have had experience with other YHM products over the years and the quality you receive for the price is outstanding. This mount may seem like a small, unimportant part, but if you are going to mount your optic to it, it must be solid. Time will tell if I have issues holding zero with this set up, but it was worth the purchase to test some options.

Put on my FS2K. Fit is absolutely perfect. Tight. Doesn’t budge. Solid and heavy duty. Holds zero without flaws

Worked well for me. Did a great job raising the optic to a more manageable height and avoid having to purchase multiple mounts for different style optics. However fitment was a bit of an issue, after loctite and marking the screws I did find that it would should shift forward and aft on the pic rail after extended use. I hope they come up with a two piece design that would fit more snug to the receiver.
