AIM Sports M4 Carbine Drop in Quad Rail Handguard

38 Customer Reviews

"Great quality and finnish. Note this is a REAL STEEL rail so all the reliability is there but you may have problems putting it on. This is built to the specs of an AR-15, so if your gun is slightly out of spec, you may have trouble and may have to modify your gun/rail to get it on. Other than that a great buy, and resonably priced considering the quality.

"The very first RIS conversion that fits into your gun in less than a minute. It needs no work/disassembly/experience to put this one in. I've been working with RIS conversions for a while now, and I've finally found one that is best so far.

Of course you have to have a PEQ box to fit the battery in and do a little bit of wiring fix to fix the battery in there, but once you've got that nailed out, you're good to go.

The rail is very sturdy and good quality. I dropped it on purpose to see if it'll break, and no, it held on good. It also withstands great abuse with a vert grip on. Get a better rail cover though, not a fan of the covers that came with it.

Highly recommended. Fits my KWA M4A1 real nice as well as my G&G Combat Machine.

"Awsome rail system. I got it in the mail, and was liked it instantly! the quality of the metal is very satisfying and unexpected for the price. my only word of advice is that you be VERY careful with how tight you make the screws unless you WANT to mess up your handguard cap. Also be careful with the rail covers you select if you don't like the ones it comes with. It is very sturdy and is perfect for people that love customizing their M4's. It comes with 12 rubber rail covers that you see in the pic.

Pros:
Sturdy
Number marked rails
Includes necessary alen wrench needed for installing
Feels good to the touch
Fit perfectly with my M4
LOOKS SEXY

Cons:
Sharp rails (they can and WILL cut you if your not careful, I got cut by them)


Final analysis, Great for those that like to get the authentic look and feel on their guns. Very strong, sturdy, and durable. Perfect for airsofters, and its A GREAT DEAL FOR THIS PRICE! It's a five star MUST!

"can the battery connector fit through the holes in the rail?

Webmaster: Yes. You might need to use a tamiya tool.

"It'll fit, but you will have to store the battery in a battery box on the rails. Or, you could wire it to the back and put the battery in the stock or an external pouch.

"will these fit on my jg m4a1 carbine weher the battery is stored in the foregrip

"Sorry dude but I've been barking up that tree for a long time. The only solution is either a CASV or a SIR rails. Acutally if you look up Mosquito Molds rails they might be able to fit a small battery in it try that MOSQUITO MOLDS rails. But it's like 110 plus getting the extra battery. But if your rich or willing to spend the money. The problem is that I've tried to find reviews cause I want to make sure, you never know what you buy on the internet, but there's no reviews I found. But there's a chance, I just don't have the money. I hope this helps, any questions just post I always check this blog.

"So will it fit on my KWA with no problem or what. Also no one answered my last question. Does it have 9 rail covers or 12. Cause I want all 12 that it should come with but there's only 9 in the picture.

"Will this fit a JG m4 Enhanced M733 ?
pliz tell me :D
by zeke m. on 09/18/2008
"Yes this RIS unit WILL fit on a KWA/CA M4. ANY M4 that has a real steel delta ring will be able to fit this RIS unit.
For your money's worth this is the best RIS unit you can buy. Very little no wobble at all. Good metal too, not just some cheap pot metal like all the china made stuff. IMO the slot holes look better than the round ones.. but thats just me.
by William L. on 08/20/2008
"Is a nice fit on the M4. Very sturdy and durable. The rail guards are nice, although may be hard when first used, I suggest boiling the rail guards to soften them up.

NOTE: DO NOT OVERTIGHTEN THE HEX SCREWS THAT HOLD THE RAIL TOGETHER!!!!! OVERTIGHTENING THE HEX SCREWS WILL DEFORM THE HANDGUARD CAP!!!!!
by Johnny S. on 07/19/2008
"It will fit good. Due to it is a very tight fit (which is a good thing) and G&G are knowing to have very stable front end (very strong spring tension, a brand new G&G Gr16's handguard is very tight). But I have a evike.com custom i'm legend and it has this RIS on it. It is a very good fit. Looks like you should adjust the position of the handguard cap behind the front sight, or lock it in after the RIS is on (since you won't be putting batteries inside the RIS). Make sure you have the battery wire out before you lock it in so you can connect your PEQ.

PROS:
no wobble

comes with rail covers

CONS:
hard to install
rail covers don't fit
by Daniel F. on 11/27/2011
