Interesting. America's recent NGSW (Next Generation Squad Weapon) competition is moving in a slightly different direction, especially cartridge-wise with a 6.8mm bullet and a stainless steel/bras hybrid case rated for 80,000psi. The new rifle will fire with the telescoping stock folded and comes complete with Vortex Optics XM157 'Smart Optic". The U.S. Army expects to procure 107,000 magazine fed XM5 rifles and 13,000 XM250 belt fed squad automatics with first shipments this year.
