Just won this on GunBroker and need some help.
Am I crazy or is this absolutely a 14.5 inch barrel and not a 16? They say it's a 16 and there's no mention of a pin and weld and I don't see one.
Also, it has the half moon BCG. Will a normal full auto profile BCG work with the rifle no problem??

Definitely a 14.5” barrel.
I see some discoloration near the crush washer… so it may be P&W.

A full auto BCG should work fine unless there’s an old style sear block.

It definitely looks short but brought to the correct length with the longer muzzle device.  It looks like it was welded all the way around, as opposed to a pin and weld.  To me, it even looks like you can see the heat discoloration band all the way around the barrel, which could indicate it was welded too hot.  Barrel might be toast.

When a Colt still has a half moon carrier, it is usually because it needs it on account of the sear blocks they used to use.  It will not work with a standard BCG unless someone does the work to remove the block.

ETA:  Why would you bid on, much less win, an auction without asking these type questions up front?

Could be high temp silver soldered.  

And agreed, the time to ask questions is beforehand.

I think the sear block was gone by the time the Law Enforcement Carbines came around, but Colt was still using the half moon carriers in semi-auto rifles.

1998-99 was when the first LEO marked carbines hit the market and 1/2 moons were used until the early/mid 2000's I believe. Colt never threw anything away...........  Since the flash hider isn't even a Colt/carbine style and is aftermarket, I'd suspect it's welded.

The one thing consistent with Colt is that they were not consistent.

Liberals are a curious mix of communism and fascism, they want to destroy you but want to use your own money to do it.

I'm getting down to the last box, the others have all been destroyed...

Well I emailed them asking if it was pin and welded and this was their response “Thank you for bringing this to our attention.
We did measure the barrel and you are absolutely correct it is a 14.5 and is not pinned and welded. Unfortunately we will have to cancel this order.
Thank you,
The GunBroker Team at Shoot Straight”
