Great product! Very easy to install, plenty of mounting screws and holds very well!! Allows you to add whatever wherever

Very fast shopper. High quality. Will definitely buy again. Thanks

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 product at a good price. Never had any issues with these, they are as good as any name brand ones but are cheaper. Always packed good and easy to use.Will buy again and again.

Rails fit all my weapon handguards
