Default WTS: Colt M4 upper SOPMOD 14.5" w bcg/ch $SOLD

This upper started life out as a LE6920(Civilian M4) and later on I got the opportunity to pick up a RO921hb barrel and jumped on it.

The RO921hb is the NSW/SEAL barrel that they spec'd on their M4's due to barrel warping/bursting during sustained automatic fire. You can read more about it here:

http://www.ar15.com/archive/topic.ht...&f=12&t=558222

I also added a Larue FF 7.0 rail when I swapped out the barrel. Below is a summary of what is included:

- Colt M4 upper receiver
- Colt RO0921hb 14.5" 1:7 chrome lined bbl
- A2 flash hider
- Colt FA BCG/CH assembly
- Larue FF7.0 rail assembly
- Magpul AFG grip
- Misc rail panels attached(BUIS is NOT INCLUDED)
The upper was test fired after it was assembled and has been stored ever since. I just purchased a hk 416 upper and this is why I'm selling this upper.

SOLD!

It was test fired with a few mags after new bbl; no more than 100. The upper receiver has seen thousands of rounds.

Local pick up in San Francisco.

Is the flash hider a pinned and welded extended A2 or is this an NFA SBR - pistol upper?

It is not pinned and has an A2 flash hider. It is therefore a pistol/nfa upper. I have a few people looking at it tomorrow.
