The SG551 was initially developed in conjunction with the SG550 under a Swiss Army requirement. Initially the concept of a main rifle (SG540 and then SG541) with a shortened Headquarters Carbine (SG543). However only the long SG541, and later the SG550 was a adopted and produced as a singular solution for the Swiss Army and the SG551 ended up as a rifle developed without adaptation by the Swiss Army. So how did it end up in French hands for special operations use? How does the carbine shoot on a fixed course? We find out.
