Picatinny Rail 3 5 7 13 Slots Aluminum Picatinny Rails Section Adapter with 9 T-Nuts 9 Screws 3 Allen Wrench - 4 Pack

The finish is a little rough compared to the big brands but for the money that these cost they're very nice. They locked up very solid on my MLOK rail. The other small thing where they cheap out (due to how cheap they sell these) is that unlike the bigger, more expensive brands, they don't have form of thread locker on the screws. I ALWAYS use blue thread locker on ANY mounts that get attached to a rifle. Otherwise they'll get shot loose in no time. This wasn't a big deal for me because I've always got some blue thread locker on hand. I put a drop on each bolt before I installed the T nuts.

I show the breakdown of my Ruger AR-556. Removing the forward grip, layout of all parts, new & existing from weapon. Then assembly. The view down the forward grip shows the screws protruding past the assembly nut. You can either trim them flush or as long as you keep everything centered, it will go back together very easy.The aluminum rails you've just received are of high quality, powder coated aluminum and do NOT scratch easy or mark up easy. Very excellent choice on these and very very satisfied. You can use any combinations of placement. I highly recommend the Loctite Heavy Strength in assembly.Great choice. High quality and everything as itemized.

These rails are narrower than mil spec. Any device you mount will only fit VERY loosely. Totally unacceptable and returned. Now I'll cough it up and buy Magpul like I should have to begin with.

Fit on my AR-15 pistol and rifle fast and easy. Holds tight. No complaints.

These rails are awesome and so easy and simple to install. I used 3 of the 4 and took no more than 10 minutes to open package and install all 3. They lock into place and are so much better than the poly plastic crap they have out on the market. I had the poly plastic and everything moved or vibrated at some point and if you have sights on plastic , you mine as well just shoot in the dirt bc after about 5 rounds your sights are gonna be off. I definitely advise going with these light weight aluminum , easy to install rails. And they are the cheapest price of Amazon that I found but they are very heavy duty and don’t move.

These rail sections worked out perfect and then to have 4 different sizes for different mounting locations they were exactly what I needed. Super easy to install and at a great price!

Works great on my AR-15 Pistol and rifle. Used it to mount angular grip, flashlight and bipod.

They are great to add things to the rifle. And they sent a second set just like the description says
