This system is intended to be used as a direct attachment method for gun accessories such as flash light mounts, laser modules, sights, scope mounts, vertical grips, rail panels, hand stops, barricade supports, and many others, which also be used in Airsoft.

"Horrible for me.

The APS barrel nut will not slide into the rail. The rail almost looks like the diameter tapers down so that its too small the slide barrel nut into it. Making this whole thing impossible to assemble and essentially being a waste of money.

"I received this RIS today and unfortunately I have to rate this a 1/5.

First I noticed that the box had been resealed with scotch tape. (no biggies right?)
After unpacking it I noticed it look like it had been in a fight with a grinder and a wire brush. Only on the inside though... Weird..
Tried to attach to my A&K M16, Barrel nut fit great! But the next step is sliding the RIS over the barrel nut to mount.
That's when I realized why this thing looked like it was in a fight. It wouldn't fit over it's own barrel nut to attach as shown. I tried some good force, yet nothing would work. Defective product...

After taking it back apart, I sadly stared at this rail system I bought.. Got an idea! I put the barrel nut in the wrong end to see if it would fit. Sure enough it did.. To bad though. Because the muzzle support screws into that end and there is no way to attach the barrel nut to the RIS. So I believe that APS machined this part backwards somehow.. Defective product..

Had everything worked and it hadn't gotten into a fight with a wood chipper I would have rated it this:
The CNC Aluminum felt awesome and sturdy.
Very Lightweight and cool looking.
The rails mounted firmly and felt sturdy as hell.
I'm probably going to buy this same system again assuming that I got a "dud"

Now I'm waiting on Evike to hopefully send me an RMA number for an exchange. Although with all the cosmetic damage (obvious metal file/grinder work) on it I'm concerned that they'll deny me.

So be Forewarned! If you get a "dud" it's a hella bad "dud"

"This rail is extremely nice looking, comes with everything you need, as far as the way it installs is super simple and widely compatible.

the barrel nut and rail are extremely out of spec on mine, there is roughly a 1-2mm difference between them, and thus upon arrival the rail couldnt slip over the barrel nut. I have been dremmeling and filing the rail bit by bit to correct this. (much easier fix with a lathe...) this I am sure is specific to my purchase and spotty QC may explain this and why some other have had some issues fitting. This is also not the first APS product ive had to work on, it seems everything I get from them requires modification. But I love their designs and the prices are good too, so I keep comin back.

look and feel 5/5,
price 5/5
QC: 0/5
