The M14 rifle is indeed still in use by the US military. While most soldiers are issued the M16 , or the carbine version of the M16, the M14 is still used where longer range fire and greater penetration may be needed.
Which M15 (be specific), if you are talking about the M14 variant i.e M14E2/M14A1; it is the same a a regular M14.
The Standoff Munitions Disruption rifle is basically a M14 National Match rifle with a good scope. It is difficult to price, since these are NOT for sale to civilian personnel. (The M14 is classed as a machine gun) The price of a civilian equivalent is ABOUT $2,000.
