SR-25

Mk 11 is the United States Marine Corps designation of the SR-25 and its modernized version, the M110 (alternatively Mk11 Mod 2) is a semi-automatic sniper rifle based on the famous AR-10 designed by Eugene Morrison Stoner. It fires the 7.62x51mm NATO round from a 10 or 20-round box magazine.

Battlefield Play4Free
In Battlefield Play4Free, the M110 is a purchasable elite weapon for the Recon Kit. It features moderate damage, rate of fire, and accuracy, and a unique scope reticle. Due to its semi-automatic nature, this gun is better suited for medium-sized maps like Karkand and Basra. Compared to its closer counterpart, the Elite's SVD, the M110 has higher rate of fire and accuracy, as well as a larger magazine, but is balanced by its lower damage, killing in 3-4 shots instead of the 2-3 needed by the SVD. It also costs less Battlefunds and can be bought with in-game Credits.

The M110 used to be purchasable for 140 for one day, 490  for a month, and 980  for unlimited use, but is currently not available to buy. It seems to have been replaced by the M14 EBR semi-automatic sniper. This gun is now only available for acquisition via the Daily Draw. Like other Elite's guns, it once sported a tan paint-scheme with a gray magazine. However, it has been altered to a clean, black paint-scheme.
