Reviews & Ratings for Pro Mag AR-15/M4 Polymer Quad Rail Carbine Handguard PM242 — 54 reviews — Page 1

The hand guard is well made and durable. It fits perfectly on my Ruger AR556.

There was another review that says this guy needed a tool to put this on. Either I have the worlds strongest hands or he has the worlds weakest hands. This popped right on. Works great and now I have rails.

Super loose lockup. Massive amounts of movement. Saw good reviews and figured if it wiggled some I can just shim it with tape. Nope, this isn’t worth it. I’ve had Midwest Industries and P&S drop in rails that are far superior, I will be exchanging.

I installed this on my PSA Carbine upper and it fits very well. There’s a slight amount of play, but for a knockoff SOCOM build that I can take to the range it holds up just fine. Drops right in and centers fairly quickly. For a polymer quad rail this caught my eye and I’m glad I decided to try it out.

Cheap. Fit on my M&P Sort Gen 1 with no tools needed. The rail system is solid but there is a bit of play. If you’re mounting a light or a forward grip it works fine, though I wouldn’t use it for an optic or angled sights.

Lite weight as expected. Seems durable and my accessories fit well.

This Quad Rail is a nice upgrade to my Colt M4. Lots of room for attachments. It's light and appears to be well made

I bought a Windham Weaponry WW-15 and asked the guy when I bought it if all the OG WW parts were still on it. Said yes. But when I checked it has a Pro Mag Quad on it. I measured 6" but it's probably 7. Anyway, my light fit perfectly and seems nice. The only markings I see are the tiny letters on a small area under the Picatinny rail identifying it. Seems nice but it doesn't fit tightly. There's a small bit of play but not enough to cause any issues, I think. Has anyone else had this problem with the fit not being tight? Oh, he also didn't tell me that he put an ATI buttstock on it, it seems nice and durable but it's a cheap piece as far as price. About the same as the Quad, $40.00!I'll probably replace it with an MFT or a Magpul Buttstock. Sooner or later I'll also replace that quad with a MFT only because that's the quad that comes stock with this Windham WW-15 model. Btw, this WW-15 M4 is a badass rifle! All in all, I can't complain because this WW-15 M4 Windham runs about $1300 and I got it for 500 and 1800 rounds of 9mm ammo!

This works perfectly. A lot better and more comfortable on your hands than the aluminum ones, It's made out of the same material as the factory stock. No need to remove anything from my Colt M4, in other words no modifications necessary, it drops right in. Also it's shaped round and feels better in your hand then the original oval shaped Factory stock.

Its a good product. Its a plastic so it is pretty lite the lock up is good for lights and grips. It doesn’t heat up under heavy fire. My only issue is that it is so thick. Looks kinda goofy and is not as comfortable to hold but with a grip who cares
