The Last Castle

The following guns were used in the film The Last Castle:

Mossberg 590

The Mossberg 590 shotgun is the weapon carried by all of the guard tower sharpshooters. These 590s are modified with Ghost Ring sights and are seen loaded with rubber bullets for the majority of the film.

Mossberg 590 with Ghost Ring sights - 12 gauge.

At the beginning of the film, a guard overlooks the yard, Mossberg 590 slung.

Cpl. Zamarro (David Alford), the prison's most dangerous shot, Zomero is armed with the 590 as he awaits orders to fire.

He hears the order over radio...

...then fires his 590.

A guard fires at the rioting prisoners.

Another guard firing his Mossberg.

Zamarro loads a slug into his Mossberg 590, instead of a rubber bullet, thus proving an earlier claim of his brutality.

M16A2

M16A2 Rifles are wielded by numerous guards when Colonel Winters authorizes them to do so, realizing that he's lost control during the riot.

But, they refuse to shoot Gen. Irwin (Robert Redford).

Beretta 92FS

Due to its resemblance to the M9, the Army's standard-issue sidearm, the Beretta 92FS makes an appearance in M12 holsters and is seen being wielded by Colonel Winters (James Gandolfini) and Captain Peretz (Steve Burton).
