Yes.
$300-550, depending on exact model and condition.
To find the caliber of an Interarms Mark X rifle with the serial number A304938, you can check the markings on the barrel or receiver, as the caliber is often stamped there. Additionally, you can refer to the owner's manual or any documentation that came with the rifle. If you don't have access to these, consider contacting Interarms directly or consulting a firearms expert or gunsmith for assistance.
Depends on what the rifle is, and whether or not you can trace it to the actual manufacturer. Interarms was an importer and distributor - not a manufacturer.
Over 3000 yds
Interarms did not make it. Probably chinese
100-200 or so
It was early, but not the first.
although the interarms is a good rifle. the value is not very high (don't know why) I sold one about 8 years ago for $300 and it was like new..................
Depends on the quality of the stock and bluing on the steel. A standard Mark X in .30-06 in good condition (some use and wear, but nothing bad) should fetch $350-450 on the online gun auctions in my experience. There are some variations like the Whitworth which have a higher value (it will be stamped "Whitworth" on the receiver). Also, specialty stocks like a full-length Mannlicher stock will make it worth more as will rifles in the larger magnum calibers.
