The SR 88 (Singapore Rifle 88) is an assault rifle designed and manufactured in Singapore by Chartered Industries of Singapore (CIS, now ST Kinetics).[1]
Following the poor 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 overall shorter length and 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.[1]
It uses long-piston-stroke, gas-operated action with a rotating bolt. The gas piston and gas cylinder are chromium-plated. The gas system features a three position gas regulator – two open positions, for normal and harsh conditions, and one closed for launching of rifle grenades.[1]
The barrel is equipped with flash hider, which also serves as a rifle grenade launcher. The lower receiver is an aluminium forging, and the upper receiver is made from stamped steel.[1]
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.[1]
