The M-110 SASS replaced the SR-25. And as for the bolts not holding up, was due to lack of scheduled maintenance for rounds fired, we have the same problem on the M4's. I've personally had 3 bolts break on me, 2 in country and one in training. We just shoot too many rounds for Crane to keep up with the maintenance for headspacing and chamber wear. Not to mention poor quality parts making their way into the supply system due to low bid contracting and short supply.... LMT finally took over most of the parts supply contract and lots of issues have dissappeared. Crane does what they can with what they are given. KAC makes great guns, just to damn expensive to field rapidly.
