Generic, all AK's, with the exception of the Yugoslavian and the Century Arms Yugo clones, have chrome lined barrels.

That rifle is an Arsenal Inc. SA-M7 Classic. They were limited edtion rifle, built as clones of the Type 3 AK-47, which entered service around 1953.

These are going to run in the $1000.00 range, plus or minus maybe $100.00.

The alternative is the Arsenal Inc. SA-M7 Carbine, which is basically the same rifle that the US bought for the Iraqi National Guard. It differs from the Classic in that it has the lighter barrel of the AKM and a 90* gas block of the AK-74. It's an updated AK that uses a milled receiver. You should be able to find them for a little under $800.00.
