Good product so far. I haven't been to the range yet so I'm not sure if they are going to pop off after first round but they feel pretty secure. The sizes were a little Shakey for my 9mm carbine but that was expected. It didn't come with instructions on how to install and for the first time I had a little trouble finding a YouTube installation video. I had to take my fire arm apart to install it behind the barrel sleeve which required me to have to go get Allen wrenches the next day to fit my weapon. A little anoying when you have a scope and red bean still in the box waiting to be installed. In all it did its job and I'm happy I'll update after I go to the range.....

I was a bit skeptical for this for the price but its a nice thick picatinny rail and installed perfectly on my Boss 25 Keymod slots. Havent gotten a chance to use with it yet but so far i dont think it'll be moving at all.Edit: They are good keymod rails but unless you install some loctite these will come loose and possibly off while at the range, mine have came loose a few times and came off once while i was using it. still with some red or blue loctite these are perfect for the price.

The parts are solid and the machining and coating are quality. The parts are a little heavier than you would like, but you know that when you are buying. This is pretty much WYSIWYG.2 notes:- The parts list in the product listing says 7 screws and nuts. In the set I received there was one extra of each (8 screws and nuts total: 3 for the 13-slot and 2 each for the 7-slot and 5-slot, plus one extra).- I checked the part weights. I found:13-slot adapter: 43.35g; with 3 screws and 3 nuts: 49.35g (1.74 oz)7-slot adapter: 23.95g; with 2 screws and 2 nuts: 27.95g (0.99 oz)5-slot adapter: 17.20g; with 2 screws and 2 nuts: 21.20g (0.75 oz)

Solid. Well made. Fit and finish look good.I used this for something else. I have a .22 cal Benjamin (synthetic stock) Marauder Gen 2. I wanted to mount a bipod and a flashlight under the stock on the forearm. The 13 slot rail works perfect. I removed the existing swivel stud. Clamped the 13 slot rail on the center line of the forearm. Drilled 3 holes. Mounted the rail with 3 countersunk stainless steel flathead 8x32 5/8 long screws. I used SS fender washers inside the stock for more support (probably not needed) .Now I have a solid rail for my bi pod and flashlight. Works great!

It's on but I've yet to use it. I did put on a bipod just to see how it all went together and I'm happy with it. The fasteners seem good enough. It's a great value!

allen/hex key wrench doesn't fit snugly and screws round out easily. I tried to find another size that fit better out of my set of allen wrenches, but neither metric or standard was any better than the included allen wrench. I had to beat a torq bit into one screw to get a bite so I could get it back out. Other than the screws, it's a 5 star for the price... but these bad screw heads are a deal breaker for me.

I was a bit skeptical at first when I saw the great price and not just one Keymod Rail Section but 3 Keymod Rail Sections! Thankfully I went ahead and ordered it and it arrived in two days. It's obvious the rails are made to Keymod specifications as they fit nice and snug on my AR at the 6 O'clock position. I'm using the longer rail to mount a Magpul AFG-2 Angled Fore Grip.

Great rails!! Seriously, I'll admit I was skeptical what kind of stuff I'd get buying gun parts on Amazon. These rails are rock solid, hold in tight, and just plain work. I've had problems in the past with rails I've gotten at the local gun show, with them not installing flush or the screws loosening after a few hundred rounds. Not with these guys. Would I buy these again? Yes, in fact, I did. Got a second set of these for a rifle I'm helping a buddy of mine put together.
