Product Information:
I got this for my KWA LM4C to make it look more like a Mk18 CQBR, and received it not too long ago. Upon first inspection it is a lot lighter than I expected but still feels like a solid bit of aluminum. It wasn't scratched at all, and it came with everything needed, except an hex key and screw driver, to put it on. The black matches up with my receiver, not darker like I heard it might be, and the trades are painted on clearly on the top rail and on the inside of the bottom rail section. The rails aren't sharp either so I might not even need rail covers. All in all, this rail system seems like a quality piece and it looks great for that aggressive CQB M4 look. Worth the money!

Sits flush with your receiver, giving an uninterrupted top rail.
Light but solid
Simple installation
Beautiful trades
Perfect shade of black to match most guns

You need to drill out the hole to fit in your mock gas tube, but not a big deal unless you need it to look that much more realistic.
I with the bottom rail came down a little further, but that's more aesthetic than visual.
Functionally nothing, wish it came with tools though.

Product Information:
This is a superb rail system, I ordered it from another website and have had it for about a month. I've used it for a day in CQB, at 2 field games, and in a night game. Very lightweight, rigid, and sits flush with my receiver. Full trades are awesome, the removable bottom rail is cool but it's really only useful for having a grenade launcher or possibly trading with a buddy. The only problems that I've found is that if you attach anything that has a metal mount or screws it will scratch the rail, and that my AFG fits VERY snuggly on the rail. I took the screws out of the AFG and it slid on a little easier, but it was still tight. Also, it took me about 10 minutes total to attach this to my gun. There is a base plate that you slide on that fits into the gas tube slot, a ring that you tighten down on top of it, and then you just slide the rest of the rail on and add the 6 big bolts and you're done.

Lightweight, looks AWESOME with a 10" barrel and an aggressive flash hider
Tons of rail space, I use an AFG with a Magpul RVG behind it for clearing rooms
NO WOBBLE whatsoever!! This rail WILL NOT MOVE once it's on!!
Sits flush with my 10" barrel
Sits flush with my receiver
VERY simple to install, 10 minutes and you're done
Rails aren't very sharp, unlike other rail systems I've owned

Finish scratches easily while using metal attachments, showing the aluminum shine below
Very tight bottom rail, but you can just take apart your grip or sand the grip down to fit the rail
Very dark black, might be different than other black on your gun

Other than those, amazing rail! I would buy another one in an instant if I had another M4 to put it on.

Product Information:
This RIS came with my G4-18 CQBR. It is very solid and built extremely well. It's construction is solid yet light weight. The lower rail detaches from the top and side rails fairly easily (just remove four screws.) There is NO wobble whatsoever. The paint doesn't scratch as easily as other RIS usually do. Most grips fit rather snug (I use a Magpul AFG1), however from my experience grips that attach via the center post that you screw up from the bottom (innuendo!) won't attach well and will wobble. With nearly 10" of space it's a lot of "real estate" and probably more than you need, but that's not really a con. The one complaint I have is that the bottom rail does not go all the way to the magwell because there is a lug for one of the screws that bolts the rail to the receiver that sticks out past the rail. If you like mounting grips almost against the magwell or you have one of those mgrips it won't work. That's not an issue for me though. (It isn't really that big of a deal but you have to wonder what they were thinking when they designed it.) The top rail sits seamlessly to the rail on the upper receiver (completely 100% monolithic). All in all this is a great rail for any M4/M16 platform.

-light weight
-solid construction, FULL METAL
-paint doesn't easily scratch or chip
-monolithic rail (mates right up to rail on upper receiver if you have one)
-no wobble at all!
-best rail if you want to mount a shower launcher or just have that SEALs look to your gun
-most importantly: LOTS OF SPACE!
-if this hadn't come with my G4 and I had an M4 I would probably choose this rail and I feel it is well worth the money

NOTE: If you want to see how this looks on an M4 check out the G4-18 CQBR or G4-18 Carbine

-some QD grips will not fit (they aren't very good in my opinion anyway but they're cheap so lots of people use them)
-bottom rail design flaw (see above for detail)

Product Information:
I love this replica RIS just as much as the real thing. These rails are the highest quality and are very very solid. It fits my Classic Army blowback M15a4 perfectly, and for those of you worried about the threading of the barrel nut, it screwed on to my CA's reciever threads effortlessly.

Only complaint is the the rails are about 1mm taller than the rails on my upper reciever, so trying to mount optics between the two is difficult. I just added a few strips of electrical tape to my reciever and mounted my old RAS fix to bridge the two pieces. My aimpoint and Eotech 551 mount on top of the RAS fix and the setup works perfectly.

Also, make sure to tighten down the Hex screws on the bolt up plate like you would lug nuts on a tire. If you just haphazardly crank down on them the rail will be a little crooked.

My favorite part of the rail is the fact that the bottom comes off. This makes accessing the wires on my M15a4 very easy. My gun is wired to the front, and normally with free float rails you have to disassemble the entire fron end of you gun to thread the wires through the hole in the front. Since the bottom rail comes off it makes disassembly much easier.

Well machined
Fits CA threads
Bottom rail comes off for easy access to wires (or to mount an M203 if you want)

1mm higher than the rails on my upper reciever (no big deal really)

It will not accept a mock gas tube unless you drill out the hole yourself. It's about half way drilled already, so all you have to do is drill the rest of the hole out. (again no big deal, but let someone who knows how to use a drill properly do it for you)

Product Information:
Being a Systema PTW owner and a real AR owner, I tend to be a bit picky about accessories and the quality. Having a real Danial Defense rail and knowing what they cost I wasn't expecting too much in terms of quality from a $110.00 dollar copy.

I must say, I was pleasantly surprised. This rail is simply amazing in all aspects. The machine work, the finish, the trademarks, all top notch. If someone handed me one of these rails not attached to an Airsoft AEG, I doubt I would have known it was an Airsoft product.

My only real complaint is that I did not buy this for my Systema PTW, but for my MAGPUL PTS M4 Carbine which is made by G&P. I did not learn until after I had placed the order that this rail does NOT fit the G&P upper without re-cutting the receiver thread. This is something Airsoft GI failed to mention about this product.

Other then that, I'm very happy. Right now I'm trying to track down a G&P barrel nut as I don't want to re-cut my threads.

On a side note, Airsoft GI does offer a Madbull thread die that will re-cut your threads if you want to go that route. I also hear they are working on getting the G&P thread barrel nuts.

Full trademarks!
Mounting hardware (screws) are very high quality.
Finish is very nice looking, very good quality.

Will not accept a mock gas tube without a little work.

Does not fit G&P upper receivers without re-cutting the threads on the upper receiver OR tracking down a G&P barrel nut which rumor has it, the supplier now has at there warehouse.

Product Information:
This RIS is absolutely amazing. Getting it on was quite simple on my G&G GR16. It is very sleek and very well made. The ability to take off the bottom portion of the rail is quite nice for mounting an m203 launcher. The feel is very nice and there is no movement in it at all!

-Very solid and well made
-No movement or wiggle room
-Looks sexy!

-Can't fit a battery, but I use a full stock with a large battery anyway. Anyone else can easily setup a PEQ box.
