Mod: Shortened Retaliator Barrel

This one's purely for tacticool, since it's been pretty well established that Nerf faux barrel are typically more detrimental to performance than helpful.

This shortened barrel is pretty easy to make. Just cut a regular Retaliator barrel down the middle, just in front of the screw ports. Then add useless tacticool things to make it look cooler. In my case I added barrel's iron sight and the muzzle from an Alpha Trooper.
One important feature I kept was the bottom tactical rail. Because of the blocks that usually keep a grip forward, these blocks now serve to keep attachments from falling off, since the usual tactical rail lock has had to be removed.
More pics after the break.
Here's the shortened barrel against some other barrel extensions.

You can see that the shortened barrel is just a little bit shorter than the Spectre barrel. The Spectre barrel causes less range loss though because its faux barrel is wider. The shortened barrel is of course about half the length of a regular Retaliator barrel. Compared to a Longstrike or Longshot barrel, it's about a third of the length.

Here's the barrel on an N-Strike Rayven. It works pretty well as a grip since the Rayven isn't really designed for two-handing. Add some attachments and you get a really cool looking carbine-y thingy.
I'll be getting an Elite Rayven in a few weeks, so it'll look even more awesome.

Here's the barrel on a Retaliator. It doesn't work that well without a stock, but with a stock it looks again like a cool carbine-y thing.

And finally on a Stryfe. Again it looks pretty cool and carbine-y, and again for me it doesn't seem to work well without a stock.

Here's some shots of the front, as requested.
Naturally being a barrel extension with a faux barrel, you'll lose a little muzzle velocity and thus range by using this attachment. But personally, I'd definitely use it on a Rayven or Retaliator for comfort for my off hand, since without attachments neither of them is great for two-handing.
