Does anyone know if this barrel has a chrome lined bore. I know Colt usually only chromes the bore of military profile barrels and only chrome lines the chambers of most others.

This is the lightweight profile barrel with a 1/7 twist. I want to have an upper built with this barrel, but only if the bore is chrome lined.

Also, does this barrel have M4 feed cuts?

Thanks in advance for any help.

You dont know much. I never had a Colt barrel that wasnt chrome all the way thru. I beleive the upper has the cuts. GG

GG, Colt stopped Chrome the barrels of their civilian (postban) rifles a few years ago. Knightone - It will be chrome throughout - wheather of not it has the cuts will depnds upon when it was assembled (barrel extension wise)

Thanks KevinB! I guesss I will have to ask before I buy. Guru, you're right I don't know much (at least about aspects of specific Colt barrels), that's why I asked the question. Apparently you don't know much either, considering the answer we got from KevinB. I've read many of your replies and I have read many of KevinB's. I am more inclined to believe KevinB on most occasions.

But they dont have chrome chambers either. I have never seen a Chrome chamber non chrome bore barrel from colt. Only hearsay.

GG, I would tend to agree with you there from logic, however I don't have any Colt barrels beyond the RO977, RO921, and 20" 1:7 "M16A4" upper (with M4 cuts) which are all milspec chromed. Colt, at the SHOT SHOW, claimed [u]all[/u] their guns have Chrome chambers - I dont have one to disprove them so I am (reluctantly) taking them at their word.

I have 2 Colt 6520's that are both chrome lined bore & chamber. The rifles are preban of course. Not sure about the new ones. Both have M4 feed cuts.

I had the postban 16" 6731 model, chamber was chrome lined, bore was not. I believe all thier postban models are like that, with the exception of the new M4 model and the accurized rifle.
