Stack Light Rifle

The Stack Light Rifle is a light gun that was manufactured by Stack Computer Services for use with the ZX Spectrum, Commodore 64, and VIC-20. It was released in 1983. The rifle is bundled with three games on tape: High Noon, Shooting Gallery, and Grouse Shoot for the Spectrum. Different games were offered for the Commodore 64 and VIC-20 versions (all the games for these two systems were included on one cassette).The Stack Light Rifle is differentiated from future light guns as being realistic looking.

The main pistol is attached to 12 feet of cable which ends in a dead-ended ZX81-size connector which plugs into the Spectrum's user port. A barrel, stock and telescopic sight can all be attached to the pistol. The barrel actually facilitated the gun's performance as it filtered out ambient light. These three parts combined to provide a reasonable – if not perfect – degree of accuracy, and allowed the user to effectively use the light gun from the comfort of an armchair.
