Matrix 12" M16RIS Handguard for M4/M16 Series Airsoft AEG Rifles

"An overall great RAS for any M16. It says here that it comes with rail covers & that the delta ring is not included, but in my case it's the other way around. I can't complain though. I needed that delta ring in order to fit it onto my ICS M16, since the stock one won't accept the standard RIS/RAS systems that require the Real Steal style.

Pros:
-Great Enhancement for ANY M16 length AR-15. Models the M5 RAS on the M16A4 RAS's that are used today.
-Tons of rail space.
-2 Piece rail system. Remove bottom rail to attach a Grenade Launcher directly to the barrel for increased stability.
-Shockingly light. I expected to gain about another 3-4 Lbs. after switching from the stock Plastic handguards on my ICS.
-Great build quality.
-Great, clearly visible laser etching with rail slot location things.

Cons:
-Rail Dimensions are a bit smaller than mil-spec, so you might have your accessories wobbling. I have a vert grip that works fine though, but my scopes & other sights won't stay still. I'll have to see how my rail covers stay once they come in with my next order.

"The rail itself is very high quality for being Cyma accessories, and the markings are laser engraved and look very close to a real M5. Be careful which M16 you're adding it to however, I originally bought it for a G&G M16A2 and it took too much work to mount it to have it terribly loose on the rifle. However I added it to my G&P M16 slabside and it fit perfectly, even without adding the included delta ring which is wider to accommodate the rail. It would fit even better with a more modern M16 with the A2 style handguard mounting hardware. I would say if you're interested in the rail make sure the M16 you have is closer in design to the G&P in terms of dimensions at least. I'd give it a decent 4/5 as long as it mounts properly, and in already planning on buying another for another rifle build

"Its a decent rail system. I bought it for my G&G M16. As of now, it still isn't on my gun, After a few hours of messing around with it, I've determined that it disagrees with a mock gas tube. I pulled the gas tube off my gun, and the rail fit. With the tube in, it does not want to seat properly into the delta ring. It's a good rail. Nice markings, light weight, and good finish. Unfortunately, the rail doesn't seem made for rifles with a gas tube. Also, the package does not include rail covers. Not a big deal given that the rails aren't sharp at all.

Pros:
Lightweight
Clean markings
Nice finish
Rails aren't sharp

Cons:
Actually does not include rail covers
Does not accept a gas tube properly (at least for my G&G)
Installation is unnecessarily finnicky
