Need help to identify this rail
 

I bought a front end on the forum that is suppose to be a HK416 front end but I know that it's not so I would like to get some other views about it and hopefully Identify it.
Thanks.

Looks very similar to a PDW

I have the PDW in the picture and while the rail in question is loosely similar, a lot of the PDW's uniqueness comes from the fact that the rail is part of the upper, whereas the pictured rail is clearly two pieces.

If it's claimed to be a 416 rail, I'm guessing it's also much bigger. I've also noticed on 416 rails and uppers that I've seen that the rail is raised quite a big height off the receiver compared to an m4, whereas the PDW is much closer to an M4 height.

It really does like a PDW rail set or a S-system but I'm sure it's not a 416 rail. He is trying to say it came from a G&G PM416 but I can't find a G&G PM416 that looks like this.

Does anyone else have a G&G PM416?

The raised rail on the receiver is the giveaway that it's a 416 receiver.
The rail? Not sure, but it matches up with the 416 receiver...

That's actually not a 416 upper, those are awkwardly high.

The rail system is most likely a modded KAC RAS, you can tell by the 2-2-2-1 hole arrangement. If it was, both ends were cut off as a portion of the weld bead is missing. Don't know how it's attached tho, custom work I guess.

That looks like a KAC type gas block.

On a 416 upper the "bump" opposite the ejection port should be round like in this photo (thanks Soldier Systems). Not square.

Reason it looks like the PDW is the original company is the same...

Looks like a KAC 7" RIS kit with raised top rail...

Sounds like a crappy chinese rail... and finish makes me think the same too.

I know some of theses rails came with the top one removable and a spacer included to install it on 416s... check if you can unscrew the top rail and see if there is a spacer.

*Edit* That is not either a 416 upper or front rail...

See included pics... bottom is WE HK416 receiver, top is ICS Colt M4 receiver... notice the difference in height of the top rail...

This rail is exactly 6.5 inches long, that's way too short for a 416. It's the same length as my aftermath M4 rail.

Check out the pic where the rail 416 rail would mount.

That is where the gas block would go. The 416 rail is secured by a screw at the receiver end.

It's just a bunch of parts thrown together. If the guy you got it from won't tell you what it is then you're out of luck.

It never was and never will be a 416.

Looks like a front end off of a g&g raider m4 to me....i had one and it looked exactly like that.

BINGO! I knew I've seen that rail before. I removed one for a customer awhile ago. It's from G&G and the way it mounts to the barrel nut is a bitch to put on and take off.

that's what i figured, and normally the only way to keep it on is by leaving the front site post on as it's a one piece with with flashhider and end of the barrel, that's why there's a gas block on the barrel.

Thats not a 416 rail. whoever sold that to you is wrong. Did he say it was a HK416 rail or front end, well it looks more like a regular KAC 7" rail. Its not even close.
