Just a note: I have used the Israeli M14icon sniper rifle system in combat in the reagion. The single point mount and Nimrod scope are as accurate and rugged as they need to be. The mount needs a bit of blue lock tite to keep it secure. Once you zero the weapon with the ammo you will use it holds zero very well. Keep in mind that sniper weapons used in combat are not fired as much as they are on the rifle range, and don't tend to lose there zero as long as they are not dropped hard or dissasembled. Keep in mind that in combat it's not how many you shoot, it's who you shoot that counts. A sniper may only fire 2 or 3 rounds in a 24 hour mission. The Nimrod scope is quick and easy to use in combat, and holds up very well in those conditions.
