The EM-2 was the result of a British research and development program looking for a replacement for the venerable Lee Enfield rifle after WWII. As with just about every other country on the planet, they were largely influenced by the German Sturmgewehr, and the program was built around the .280 Enfield cartridge. This was a good intermediate-power cartridge, firing a 140 grain bullet at about 2450fps – slightly more potent than the Soviet 7.62×39 and the “new” 6.8 Remington SPC.

The EM-2 used a long-stroke gas piston mounted above the barrel, and a locking system similar to the German G41 and G43/K43 selfloading rifles. Two flaps were mounted in the bolt carrier, and would pivot out to engage locking recesses in the receiver when in battery. The system was a bit complex, but effective and well sealed against dirt and dust.

Disassembly was simple enough, as the buttplate could be rotated up and removed, allowing the recoil spring, piston, and bolt carrier to slide out the back of the receiver. The safety was located in the front of the trigger guard much like the M1/M14 rifles, and the magazines were of the “rock-n-lock” variety, with an AK-like latch at the back of the magwell. The optical sight  was fixed; zeroing was done with screw adjustments on the front of the carry handle.

The EM-2 was chosen over the EM-1 rifle as an standard service rifle as the No9 Mk1 rifle in 1951. Before it could be put into serious production, though, the government decided to indulge the US and adopt the new 7.62×51 cartridge instead (thus paving the way for the L1A1 rifle). A few decades later they would return to the bullpup configuration with the L85 rifle (which bears no mechanical similarity to the EM2 except gross configuration).

Manuals

I managed to skip a couple pages when I scanned this, but better to have most of it available than none, so here it is (less pages 4/5, 22/23, and 28/29). The full material is available in Dugelby’s book, although it is out of print and difficult and pricey to find.
