chrome

I am purchasing a CM barrel and I was wondering if they need to be blued. I have heard that with a CM barrel it needs to be blued in order not to rust. Is this the case? Thanks

Are the actions of all chrome moly construction ?

I'm in the market for a new AR Bolt assembly. I wanna do it right the first time and was looking at 4 diffrent types of bolt assemblies. Here they are: 1. Fail zone (basic kit) 2. Larue (non chrome) 3. National Match Bolt Carrier by Young Manufacturing, Inc (chrome) 4 LMT (chrome) Is it...

I was speaking with Krieger barrels and they said that if the bolt is chromed, there MAY be insufficient headspace with the barrel. The reasoning being that if the bolt is made to milspec, and then chromed, the chrome will eat some headspace. I have a Young Mfg National Match Chrome Bolt...

I have read several posts about people cutting chrome lined barrel on AR's as well as the FN rifles. I always figured if you cut through the chrome it would peel/flake. Any of you guys have any that you have cut? How did it work out?

I have heard that ammonia will damage a chrome lined barrel. Is there any truth to this?

What do you think makes a good barrel lining?

Trying to figure out if this is chrome lined...it's a R4 Light profile barrel on a RRA LE Carbine.
