I have been tasked with updating our sniper program with new rifles. We are currently running the traditional R700's and they have worked very well for us, however the powers at be say its time to go semi-auto.
Uh huh. What quantity of rifles? What's the total budget? After sale service/maintenance contract or in house armorer?
Unique requirements... barrel lengths, optics, urban or suburban use, one dedicated operator or multiple operators, unusual ammo requirements, gas impingement or piston, AR type or other... etc etc.
Saying that you should get a Sig Sauer 716 or a LMT MWSE (my usual best .308 answer)... or anything for that matter would be kinda pie-in-the-sky, considering that someone else is paying for the guns and you don't state any specifics.
