PROSUPPLIES TACFUN 3 PCS Tactical 45 Degree Angle Offset 20mm Weaver Rail Mount Picatinny 4 Slot

These fit perfectly and very secure on my Picatinny rail. I'm using two of them to offset my Magpul pop up iron sights and the third for my laser. They are absolutely snug at just hand tight but I always add loc-tite blue. Photo shows the Magpul rear site closed and extended. It easily clears my Strike Eagle scope.

I read many of the reviews for this product before I made my order. These offset rails were delivered as promised and in good condition. The 3 rails I received have no issues so far and are perfect for installation on my AR-15-22. Based on the rails I received, I would even install them on some of my AR rifles (and probably use some blue loc-tite just to make sure the nuts don't start backing off the rails).Upon reading some of the reviews that are posted on Amazon....let's be real. If you have a 50 Cal BMG rifle.....spend the money and purchase rails that are worthy and / or designed to match the rifle you purchased.I would recommend these rails (for the appropriate rifles) and purchasing from this seller.

Fit well on a standard flat top AR15 receiver. The only problem is that they don't give much offset, so mounting one accessory next to another isn't really a viable option (like, a red dot next to a scope). Unless you're using a mini-dot type sight anyway.Other than that, they work great. I'll add some pictures of them mounted to my three guns here in a bit.Edit: 11/4/16Turns out only one of them mounted properly. Two of them were loose on the same rail the other one worked on. Returned to Amazon.

Disappointed in this product. My $140 flip up Mag-pull sights won't fit on this rail. I can look and see that the cuts are not done precisely, and the depth is also variable. I ended up having to take a brill and metal bit to grip out the extra metal to create width and depth that might sights could then attach to. My Mag-Pul sights fit perfectly on my AR platform, so I know that it was an issue with these. But, they are cheap, so if you don't mind doing a little custom grinding on them, then they could work for you to. I still have them on my AR.

I have a quad rail handguard, and I use one of these to mount my open reticle sight on the right side forward end of the handguard. This lets me cross-train between my scope for long range, and then medium and short range work with the open reticle by canting the weapon to the left. This works very well for me, and I was able to achieve this setup with remarkably little money with one of these 45 degree angle offsets. The surprise was how smoothly I can mount and dismount the open reticle sight using the thumb nut on this angle unit. I have found that once I sighted in the open reticle, it remains accurate (at least within my own abilities) at 15 and 25 yards -- so these little units provide a nicely repeatable mount position.

Want to do that cool canted ironsights move like in the video games? Look no further than these! Extremely well built, and on the hefty side. Only issue with them is that they will not fit under a low seated scope, so make sure your setup is able to fit these in before purchase. Also a little bit expensive.

A great adapter to add accessories off the side of your picatinny-railed rifle. I had mounted a rifle scope to the top of my rifle, but also wanted to use my MBUS flip up sights, so I used these to hang them off the right side of my rifle. They fit snuggly to the picatinny on top, and the hold picatinny accessories snuggly to their grooved 45 degree face. A simple allen wrench tightens the unit to the rifles picatinny. I recommend this product.The only issue I have is that it's just a hair too chunky.

Ok. I read the other reviews. Here is my take:If you are looking for magpoll quality. Then go spend the money on it.One reviewer complained that they werent tight enough an rattled.To "fix" this i did two things.1. Added plummbers tape around the shaft of the screw to make up the difference.2.a slight bend to the shaft of the screw itself.Either worked and bother are rock solid.I think both are a decent work around. Make sure you locktight the nuts and good luck.
