Those are the Ishapore 2A SMLEs originally brought in by Navy Arms in New Jersey. They sold hundreds of them so I hear. Gibbs bought a bunch, cleaned them up, chrome plated them, and sold 'em out so I hear.
I spent a week or so refinishing some old drill stocks I got from a fellow freeper (thanks noumenon), and then picked up a composite sporter stock and a scope mount for it. Result? One damn fine sporter-scout type rifle with a 10 round mag chambered for a serious cartridge.
As Muttley says, the action is like butter and the bore was mint when I received mine. I doubt they were ever fired. From some research I've done via the net, apparently they aren't simply rechambered .303 Brit rifles but were completely reengineered for 7.62 x 51mm and were manufactured using modern steel.
All I know is I got a damn fine rifle.
