If you have been following this Blog, you probably already know the answer. Its the Mossberg MVP. Finally, an American made rifle with an action properly sized for .223 Remington sized cartridges. On top of that, the rifle accepts AR 15 magazines.
It has a laminated stock, heavy barrel, 1 in 9 twist, comes with Weaver style bases and is fitted with the very good Mossberg LBA trigger. As is, it is a nice and affordable (Suggested Retail $ 649.00) rifle but think of the posibilities. It could be easily rebarreled to work with any cartridge built around the .223 Remington case and with some bolt face modification many other ultra short-action cartridges.
Information on this rifle is not available on the Mossberg web site yet but for more details use the SEARCH feature on this BLOG and enter MVP.
