Does anyone know if its possible to have a non chrome lined barrel fitted with chrome lining? Would it be worth it, or just cheaper to buy a new barrel?

[SomeKid]

My understanding is you cannot, because it adds a layer in and narrows the barrel diameter.

Chrome lined barrels are made a bit wider to accommodate the added lining.

Anyone know for 100% sure?

Why? Only reason to chrome line a barrel is if you plan to consistently shoot large quantities of very dirty powder without adequate cleaning.

That that extra "tactical" money, and use it to buy a better stainless barrel.

Chrome lining is a nice upgrade, very desirable, but I would just go get another barrel.

What weapon are you talking about?

[jwr747]

chrome lining is not "fitted" it's just a plating. like you chrome plate a bumper. jwr

chrome also helps reduce throat erosion a bit, especially in rapid firing weapons.

That said, chrome plating will decrease the bore diameter a little bit. In a large caliber, say .40 and up, I'd proceed with caution. It probably won't be an issue.

In a small caliber like .224, I'd just fo buy a chomed barrel.

The only aftermarket "hard chroming" process that I know of which can be applied to the bore and chamber of a rifle or semiauto pistol and the bore and chambers of a revolver cylinder with negligible dimensional change is Armoloy. The outfit used to be located in Dagget (sp?) TX. It still was the last I heard and a quick Google should find contact info.

I had it applied to a S&W 1917 that I had customized for CCW back in the late 1970's. Everything but the springs was treated, including the bore and chambers. There have been no functional issues whatever and it still looks fine and shoots very well.

The process forms a molecular bond between the chromium and the steel. IIRC, the average dimensional change is somewhat less than 0.001"

Frankly, I can't see much, if any, practical advantage to a chromed bore over a stainless barrel in a hunting rifle. The main reason that many military weapons have it has more to do with maintaining functional reliability and adding heat and wear resistance when subjected to high volumes of fire for extended periods under extremely harsh conditions.
