Following the poor production sales of the SAR 80 and with their involvement with the Sterling SAR-87, CIS came up with an improved design – the new SR 88. Many of the parts and mechanisms are similar to its predecessor. Later production models were further improved with higher quality materials including a new handguard and buttstock, this version was designated the SR 88A. The SR 88A was built in two versions, the standard model and the latest carbine model which is a heavy-duty mil-spec version with a shorter barrel and a retractable butt-stock popularly called today as the "baby ultimax" because of its over-all shorter feature, function and frame similarities with the Ultimax 100. Its magazine catch will accept a regular M16 magazine and a C-mag which is also used in M16 rifles.

It uses long piston stroke gas operated action with rotating bolt. The gas piston and gas cylinder are chromium-plated. The gas system features a three positions gas regulator - two open positions, for normal and harsh conditions, and one closed for launching of rifle grenades.

The barrel is equipped with flash hider, which also serves as a rifle grenade launcher. The lower receiver is made from aluminium forging, and the upper receiver is made from stamped steel.

Furniture (stock, pistol grip, handguards) is made from plastic materials. The standard stock is of fixed type, but the SR 88 is also available with a side-folding stock. The side-folding carrying handle is mounted at the forward end of the receiver.
