Just thought I would get this out, We are currently using the MK17 (SCAR HVY) which is the 7.62 variant. love the gun but that's not what this is about. I wanted to let everyone know that all the 7.62 SOST, short for Special Operations Science and Technology ammunition we have received for it has been crap. can't even shoot a mag without a malfunction(only a 20 round mag for MK17s) after closer inspection we notice that the bullet itself is seated at all different depths in the casing not sure if this is a QC issue or just plain shoddy work either way were sticking with the 118LR we have shots thousands of rounds with this ammo and NO malfunctions. As for the 5.56 SOST the other teams shooting it have been satisfied with it I haven't heard any complaints.....yet
