   Exceptionally priced, and easy install. Streamlined for a thin lightweight free-floating handguard. I was so satisfied with this product that I have 3 of them. I would buy again in the future if I can catch them on sale again, it is not everyday you can find a quality 15 inch rail for a reasonable price.

   Solid, slim, light weight and sturdy rail at a great price. The brand logo is a little large but it matches the rifle in my case so no big deal. Would definitely buy again and recommend to others. Very pleased.

   Light weight and durable,put it on a 20” heavy barrel to shed a little weight .having Mlok makes it a good choice too. It color matches my closed eared Anderson lower pretty well overall I’m happy with it. The price wasn’t bad either

   This rail is slim and light weight. ))))(((Color is great and matches up to my Anderson upper. I would buy this rail again do other builds in the future. )))((( the m mods are tight fitting. The slim rail helps when shooting long range.)))((((. I would recommend this product. Looks good with heavy barrels.

   I bought the 15 inch version of this rail on one of OpticsPlanet's killer deals for sixty bucks. I had been looking for a longer rail for awhile and was not quite ready to spend the big money that most rails seemed to be running. I saw this rail in an email from OpticsPlanet and I jumped on the opportunity. I figured that even if it was garbage that at least it was the right price.When the rail showed up I looked it over to see what kind of quality I was working with. The packaging that it came in was more than adequate and protected the contents well. The finish on the rail was even and uniform but it was a shade darker black that the other components that I was working with. All of the parts were in the package and nothing was missing. The instructions were also included and they were clear and easy to understand.The rail itself is now mounted and I like that it is fairly rigid and does not seem to flex much at all. The edges of the Mlok slots and picatinny rail sections are a bit aggressive and I will definitely be wearing gloves when shooting as I could see them ripping up your hands after shooting a bunch.One bummer was that this rail does not come with a barrel nut wrench and my armorers tool from Wheeler did not have a section that fit the nut. I was able to rig something up to work with it, but it would have been so much nicer to either have a wrench included or have somewhere that says what size or type of wrench to buy before you go to install the rail. Also with this type of barrel nut, it is a pain in the butt to get it lined up exactly right so that the top rail sections are indexed properly. I worked at it for a long time and it still isn't perfect.In the end I am confident it was worth the purchase and I will probably buy another one if it ever goes on sale again. If they were to include the barrel wrench in the future then I would give this 4 stars for sure. As it stands, it is a solid 3 stars and I would not hesitate to recommend it in the future for any budget builds.

   Quick and nasty, its okay.100 bucks gets you an american made, friction fit, mlok at the 3/6/9 postion, full length picatiny on top, thin profiled, moderatly lightweight handguard.However for around the same price, I Think UTG Pro options beat it, mainly because they use a screw interface design that mates with the barrel nut which is more robust and will hold zero better than a friction fit design. If you dont mount a ything to the handguard thay requires a zero (lasers, sights) then its a non issue for you.The bad, sharp edges, friction fit design, narrow barrel passageway… meaning if you have a flash can or supressor and want to have the handguard extend over it, creating and integrated design, this might not be the correct rail for you, in fact… im going to say it isnt. I couldnt fit a KAK flash can on my 10.5 because the 12" handguard wasent wide enough to accept it. I later bought a slimline flash can and it barely fit.The good, looks cool. Has a squared feeling and look to it which feels nice up untill the sharp edges ruin it. American product. Some design choices are not what I wouldve choosen but regardless everything is executed well and it is a functional handguard. Its lightweight and thin profiled which is good if thats what youre looking for.Id still probably recommend going with UTG Pro over this tho.
