The following guns were used in the movie Malone:

Mauser SP66 Sniper Rifle

Burned out Richard Malone (Burt Reynolds) gets ready to fire his Mauser SP66, but cannot get himself to pull the trigger.

The rifle has a tactical scope

with an ajustable target stock,

and a special flash suppressor.the diagonal cut is for mounting an anti-mirage band over the barrel.

Jon Paterson, one of the followers of Delayne (Cliff Robertson) executes his target with a silenced Colt.

for a silenced gun, I think the flash is too obvious, probably they used a fake silencer and firing blanks

the mount on top of the gun is maybe for flashlight or sight?
