12 Pack Single Picatinny Rail 3 3 5 5 7 7 9 9 11 11 13 13 Slots Polymer Black

Fits great on my AR, sooo many options that I gave half the kit to my buddy... what am I gonne do with all these mounts? Seriously, share with a gun buddy, still have extras for the future!They're so strong for how light they are, not a knick and treat my things terribly if they can take it. They are quite secure, no different than the standard metal versions.I see no reason for any other, this is good reasonably priced kit!

Good quality picatinny rails. A lot of sizes to choose from. They are plastic but I new that when I ordered them.

90 day update: Fits all my accessories perfectly *except* my Magpul MBUS flip up sights. Great value vs. similar but more expensive Magpul polymer M-lok rails. Upgraded from 3 stars to 4, and buying another set for rifle #2.Original review: These polymer rail sections fit M-lock systems just fine but my problem is that my Magpul MBUS flip-up front sight has a noticeable amount of shimmy, shake and wiggle laterally whereas it did not do that on my other polymer and aluminum picatinny rail sections. However, I do not experience this issue with some my other accessories like my scope mounts or bipod. So, not quite sure what to make of this.3 stars given because it fits the M-lock system as expected and I can still use the rails for a bipod or flashlight without issue, which I do. Fine for that purpose. Just keep in mind that for whatever reason it's not going to be a snug fit for a Magpul flip up MBUS. If that is your intent, spend the extra few bucks on a proper Magpul rail system to actually enjoy your time at the range so you can accurately zero your sights.Otherwise seems to be a good product at a good price. I suppose I would recommend for any accessories outside of Magpul MBUS flip up sights.

Good value. Although these are made for the budget-minded, they are still a decent choice for any builder. They are polymer, but very well made. They fit well, and the provided MLOK fasteners stay in place.

used them for a few days not, wanted to try plastic but they seem sturdy just not what i was expecting

I honestly thought I was getting a cheap metal; they are in fact polymer. Very light! Does NOT transmit heat. Unless you’re doing some auto stuff. Than I have no idea. Anyway, they work well, some large ones came a bit flexed but went right into place without issue. Value for the money.

Very good for price works well
