For your viewing pleasure.


ArmaLite® is proud to announce the release of the new AR-10(T)™ Ultra Mag, the AR-10(T)™ rifle chambered in .300 Remington Short Ultra Magnum. The AR-10(T)™ Ultra Mag is the result of collaboration between ArmaLite® and the Army Marksmanship Program in Fort Benning, GA. The .300RSUM cartridge was selected over the .300 Winchester Short Magnum because of the Remington’s stronger cartridge case, which is more suitable for use in self loading rifles such as the AR-10(T)™.

There will be some noticeable changes to the famed AR-10(T)™ design on the new Ultra Mag rifles. The barrel has a longer gas system to allow optimum cycling with the .300RSUM cartridge. A noticeably longer gas tube and handguard reflect this change. Internally, the feed ramps have been extended to improve feeding because the .300RSUM cartridges stack in the magazine differently than the .308 Winchester rounds. ArmaLite® is also producing other parts specific to the new rifle, which, include the bolt, extractor, barrel extension, upper receiver, and magazine. The barrels are designed and chambered specifically for the .300RSUM round, they are not a modified .308 caliber barrel.

ArmaLite® is planning to begin shipments of the AR-10(T)™ Ultra Mag rifles in October of 2003. Complete upper half assemblies will also be available and are compatible with existing ArmaLite® AR-10™ lower receivers. The rifles will ship with two five round magazines designed specifically for the new rifles, and the complete upper half assemblies will ship with one magazine. High capacity magazines will not be available.

For more information, please contact ArmaLite, Inc.® at 1-800-336-0184, or check the ArmaLite® website www.armalite.com.

I remember a few years back a company called Armstech in Phoeinx was building .300 Win mag rifles on Browning BAR Safari rifles. They had Schneider barrels, McMillan stocks and 10 round box mags. Very nice but $4,000 plus. they had a small gov't contract for a while.
