#5.45x39

It went unnoticed at The Firearm Blog but, back in late 2009, Russian arms manufacturer Tula / KPB announced an underwater ammunition system for the Tula A-91 assault rifle. A modified 5.45x39mm round appears to be loaded with a long thin sabot bullet. Unlike the ASP round, also based on the 5.45mm cartridge, this newer round does not need a special rifle with an oversized magazine.

S&W have announced the M&P15R, an AR-15 chambered for the 5.45x39mm. The idea being you can save costs by shooting the cheaper round instead of 5.56mm.

I interviewed Drake Clark from Magpul about their new Masada rifle, the firearms industry and internet marketing. I was very impressed at the passion Drake and Magpul have for creating the next American fighting rifle.
