[ARCHIVED THREAD] - Help Identify this pistol upper

Posted: 1/1/2012 4:28:52 PM EDT

Hello,

I've got this pistol/SBR upper with an A2 suppressor that I do not know much about manufacture wise. I'm not even sure of the length; where do you start measuring the barrel? I'd like to do a little research to learn more about it, but I'm not sure where to start.

What do you think I have here? Where should I look for more information?

ETA: The Barrel is marked with DPMS 5.56.

Barrel is measured from closed bolt face to end of muzzle, or perm attached muzzle device.

Easy way is to close the bolt, stick a cleaning rod down the barrel, mark at muzzle, and measure.

from the pictures I would guess a M1S 7.5inch upper, I had one just like it.

Per Scallywag's measuring instructions it's 8.5" to the end of the birdcage. I didn't feel like popping the birdcage off to get a measurement on just the barrel.

Doesn't the A2 usually add 1.5"? So the barrel should be 7"? Feel free to call me the village idiot if I'm not making any sense, but please educate me while you're at it.

There's no markings that I can see. Do I need to get the hand guard off to find some hidden information? I'd like to find out if this upper can take 5.56 Nato rounds.

Alright, I found some barrel markings. I can't see much because I didn't remove the handguard, but I do see DPMS 5.56. I'm still looking for any help I can get on learning more about the upper. Is it safe to assume it's a Kitty Kat barrel on an A4?
