Reviews & Ratings for Radical Firearms First-Gen Parallelogram Rail System (RPR) — 8 reviews — Page 1

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.

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.

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

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.

If you can use a 15 inch free floating rail for an AR-15 this is a very high quality handguard. Comes with complete instructions for install. I'm sure this was a once in a lifetime special closeout deal at $59. Another plus is that it was the more desirable narrow type of rail, is not the older fat diameter type. This rail is made in the USA, & has a full length Picatinny rail. Now I'm just sorry I didn't buy a bunch more.

This is a nice lower priced hand guard. It is well made and is light weight. If price is important to you as well as quality, then this is a good choice for you to purchase. I bought this for some AR builds that I am doing. I did not want to break the bank on the higher priced name brand hand guards.

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.
