I thought the chrome-lining was designed to extend the life of full-auto machine gun barrels...I don't have it on my Rock River carbine, and it doesn't seem to affect firing or cleaning in any way that I've ever noticed.
I'm afraid it would be for me.Is non-chromed barrel on AR-15 deal breaker?
And that is some good advice.I would make sure it is chambered for 5.56 and not .223 !
The lack of chrome most certainly hurt, but another bad component was the powder (IMR 3031?) that would swell the case when moisture was absorbed. If you had a round chambered for an extended period of time and tried to extract it the head of the case could be torn off. When the powder was changed from ball to stick configuration things worked much better.QKShooter said:I only remember that the COLT NAM BATTLE version of the rifle had big time feed & extraction problems until Colt chromed the barrel chamber & barrel interior & that solved the original problem.
Just a bit of known historic fact (for what it's worth)
I don't know how relevant it is to the rifles being produced today.
