APS 10" Keymod RIS Free Float Handguard for M4 / M16 Series Airsoft AEG Rifles (Color: Black)

"I bought the 13in Red rail and it looks gorgeous, especially on my red aps receiver. If the color is different I cant tell, but it finishes it off with an awesome look. As for the barrel nut, on an aps upper, it fits great. However knowing I have had issues with TM spec barrel nuts on this upper I would expect some issues with other receivers. Gets a 10 out of 10 for me (or 5 out of 5) because when with other aps parts it looks, fits, and feels great!

"Brought this to change up my CM16 raider and have to say that this rail is amazing. The quality and ease of assembly is really top notch, the rail comes with everything you need to install except an AR wrench - which I would highly suggest purchasing just to tighten the barrel nut down easily. I would hands down suggest this Keymod rail to anyone wanting a sleek quality rail.

"NOTE: IT WILL NOT FIT G&P RECEIVERS. Other than that, this rail system is absolutely gorgeous. It gives any m4 a uniqueness and looks really, really aggressive. It took an ASTOUNDING amount of force (literally clamped the body into a vice and rotated the barrel nut with a large wrench) to be re-tap the threading of the nut to fit the body. Though 5 stars for it having turned out alright in the end!

"Currently have this on my KWA LM4. There is a slight modification needed for the barrel nut. I used some e-tape to add thickness and to prevent scratching. Other than that, the APS rail is well-aligned, sturdy, and very lightweight. I love the way it looks and feels on my LM4

"This rail is quality, the way they barrel nut and the rail itself are designed make it so it will fit perfectly on any M4. It also comes with a barrel stablizer that screws in over your barrel in the front, you can choose to use it or not. And it comes with three rails.

looks swick, works swick, is swick.

"Bought this for my G&G, and it is amazing. It is very small width wise, and that is what makes it feel great in your hands. Nice machining and trademarks, numbered top rail. It is very solid and stable and allows for in-rail supressors. Best rail system I could recomend. Wish it came with a smaller rail section though, as I use a side rail for a flashlight but hits my hand and makes the great rail feel die a little.

"Let me start off by saying that pictures do NOT do this rail system justice. This thing looks absoloutely beautiful when installed on a gun; the exterior finish is phenomenal, and the dimples placed along the corners add a really agressive look. Pair this thing up with a 10.5 inch barrel and a mean-looking flash hider of your choice, and you'll be getting all the attention out on the field. The system is extremely light weight, yet rock solid. It looks unique and very sleek, and at this price, its an absolute steal. You honestly won't find a better keymod rail anywhere; I can't recomend this enough

"this is a really good ris for the price and its sexy af. the madbull nsr is 120 and it doesnt come with any rails and doesnt look as good. a lot of people came up to me and askked me about it and it was super cumfy in the hands .

"Make sure to buy washers just incase your rail isn't flush with your upper. I learned the hard way. Other than that its a really good rail. They also provide washers but not big wide enough.

"I bought this for my Tippmann m4. I gotta say I like how it made my Tippmann look sleek and how it feels in my hand. The only complaint that can be fix is compensating the rifle's recoil. I used teflon tape to keep the barrel lug from loosening up after game play.

"Love the feel and look of this rail! It is a great improvement to any gun it's not too heavy but still makes the gun feel as it should. The reason I gave it 4 instead of 5 is because I have a KWA KM4 SR7 and it fit but there is a 2 centimeter gap in between my body and rail. But overall love the product.

"This rail looks nice when paired up with the 10.5 inch free float rail that aps makes but... take caution

I bought this for a VFC avalon and the rail was SIGNIFICANTLY lower than my upper receivers rail. So im not sure what kind of upper receiver you willl need to make this work. But I tried getting a compatibility test from Evike. And never saw a response...
