| Can you send your barrel in if it is not chrome-lined and have it chrome-lined? Thanks. |

Actually, the only company I ever was aware of that did aftermarket plating of the bores, Marker Machine in Illinois, has not been around for years. Had them do an M1 Carbine barrel for me around 1956 (yeah, I'm THAT old[:D]). Someone else made a valid point about aftermarket plating awhile back also. What you can get away with in terms of bore size reduction on a .30 caliber, will give you an undersized bore in a .223 barrel. The electopolishing pre plating will open up the bore about .0005 inch, but a plating thickness of .001 will still reduce bore size .002, meaning your now going to squeeze that bullet down a significantly smaller barrel. You can get away w/this in a .30 caliber, but it's a different story in a .223. Barrels that come plated have been rifled to allow for the thickness of the plating, so it's not a problem there. Solution? Pull your barrel, sell it on the Equipment Exchange, and buy a new lined barrel[:D] |
| I've got an upper with a 16" non-chrome lined bbl (forgive me, it was my first AR and I had no clue) that I'm replacing with a 20" FN chrome-lined bbl. I picked up the 20" bbl on the EE for $155 shipped and it's only going to cost $50 to install. Heck, you can get brand new Bushmaster 16" M$ bbl for $185 + shipping. |

The long answer is also "no", if you've actually fired the rifle. Chromelining the long, narrow bore of a .22 consistantly isn't easy, but it's next to impossible with trace amounts of fouling and copper in the bore. That's why it's always done before the barrel is fired. Even if the gun was unfired, it would likely cost in the neighborhood of $100 or more, not including shipping, to have a *single* barrel chrome-lined. Obviously contracted mass-production costs is MUCH less, but a one-off custom job wouldn't be cheap. The bottom line is: get a new barrel if you want chrome. -Troy |
| J&T was talking about bbls with a tennifer type coating. I wonder if they ever got that going. They had a post on their forum, but I don't remember ever getting a response from them on this. Getting a bbl tennifer coated would have some serious implications. IIRC someone said there were EPA issues with this type of treatment. |

The Tenifer process uses some nasty chemicals that would give the EPA fits. This is why the process is done in Austria (and why HK, who uses a near-identical process, does theirs in Germany). It's a fantastic steel finish, but you don't see it on US-made guns due to the enormous costs of complying with EPA regs. -Troy |
