The '''SR 88''' (Singapore Rifle 88) is an [[assault rifle]] designed and manufactured in [[Singapore]] by Chartered Industries of Singapore (CIS, now [[ST Kinetics]]).<ref name="JGRG2008"/>

==Development==
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.<ref>https://www.forgottenweapons.com/sr-88a-singapores-final-evolution-of-the-ar-18/</ref>

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 rifle]]s.<ref name="JGRG2008"/>

==Design details==
It uses long-piston-stroke, [[Gas-operated reloading|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.<ref name="JGRG2008"/>

The [[Gun barrel|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.<ref name="JGRG2008"/>

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.<ref name="JGRG2008"/>
