Looks like an M4 barrel that was cut down, the FSB was removed as well.

Sense it doesn't have a bayonet lug it was most likely a post ban configuration.

Interesting, I noticed the mfg markings are under the handguard.
Possibly a colt factory 10.5" cut down?

This or a 11.5" was cut down. If it was a 14.5 or 16 M4 barrel, the barrel markings would have been cut off because they are on the section between the M203 notch and muzzle.

The following was quoted from SAW's website for parts


SA02009 BARREL & FRONT SIGHT ASSY SPECIAL PURPOSE, 1/7 LWT - 10in CHROME LINED $495.00


SA02025 BARREL & FRONT SIGHT ASSY, MK18, M4CQB, 1/7 M4 CONTOUR, 10.3" CHROME LINED W/ BAYONET LUG $495.00



Ok then what were they used for?

why does the extra 0.3" mk 18 barrel warrant the bayonet lug and the 10.0" special purpose not?

sure would like to get some real info on these

10.3" is the shortest a barrel can be to have a FSB w/ bayonet lug and be able to mount a suppressor.
