ZCI CNC Aluminum KeyMod Ultra Slim Free Float Handguard for M4 / M16 AEG Rifles (Size: 12")

"This thing is great, super super solid, very light, I thought the box that it was in was empty lol. And it DOES NOT have any sharp edges. Mounting it was a breeze, it took less than a minute to get it on and all tightened in place. Overall 11/10 I love it.

Also I had a delta ring type rail (the one with quad Picatinny rails) and I didn’t need a A-R wrench to take off the old rail if you were wandering.

"Nice feel for the price, doesn't come with shims works as it should.

"Fit fantastic on a G&G Combat Machine body, however it does have a tight diameter.

I use an Acetech Lighter R and it fits into the handguard comfortably, but anything much larger than that will likely be too snug a fit to work.

Other than that, a very lightweight handguard, especially compared to a four sided picatinny Daniel Defense rail!

So long as you don't have a girthy barrel accessory, there's really no reason to pay more than $20 for a quality handguard.

"Very good, rail is quite small(like diameter wise) but no big deal, fits perfectly fine, comes with barrel nut and screws, its a bit finicky but works well. Very good price for what you get 11/10

"Just got this and it works great. Comes barrel nut and 6 screws to screw the rail into it. No barrel shims tho. Had to finagle it together ish but it solid as hell! Also it IS lol spec keymod. The bevels on the inside look a little sharper then my other mil spec keymod rail but all in all I'm very happy with this purchase. Super clean finish and decently light for all metal.

"Nice quality product. Too small for my use though. I have an EMG Guardian Mock Suppressor that I wanted to use for an integrated suppressor CQB style. The suppressor is too large for this hand guard.
