How did Beretta and Sig wind-up making such similar rifles? Beretta AR70 vs Sig 550
This video explores the surprising similarities between the Beretta AR70 and the SIG Sauer 550 series rifles, stemming from a brief 1960s collaboration between the two manufacturers. Despite a subsequent 'divorce' where each company pursued independent designs, both ended up with rifles sharing a stamped sheet metal receiver, long-stroke gas piston system, and reciprocating charging handle. The comparison highlights how both designs, while distinct internally (rotating bolt vs. roller-delayed blowback), share a common external aesthetic and operational layout.
