ST Engineering continues to refine its small arms, with new variants to debut at next year's Singapore Airshow.

ST Engineering is in the process of introducing a new variant of the SAR21 assault rifle, as well as improvements to the Ultimax 100 light machine gun, both of which will be unveiled at Singapore Airshow 2024.

The Singapore-based arms manufacturer added that the BR18 and Compact Personal Weapon (CPW) have progressed from the development stage and are in production, and the CPW has been sold to undisclosed customers.

Open-source data shows the CPW was sold to a Bangladesh police special unit.

Jackson Tean, head of ST Engineering’s Integrated Soldier Systems Division, said while both the SAR21 and Ultimax 100 are mature products, the company continues to work on improving them for current operational requirements.

‘We are currently developing a new [SAR21] variant,’ he said, without providing more details. Tean added the company would showcase a new Ultimax 100 concept at Singapore Airshow.

He said the SAR21 Modular Mounting System is an example of how the company responded to arising operational needs, moving from conventional warfare to urban, close-quarter battles (CQB) that require a compact weapon with options for the operator to install their own accessories like sights and lights.

The Ultimax 100 Mk8 underwent similar treatment, with the installation of Picatinny rails and modifications to the trigger and bolt to enable semiautomatic mode even in an open-bolt system; this enables the machine gun to function like an assault rifle. It also has a 13-inch barrel option for CQB.

Tean explained the proprietary 100-round drum option could provide infantry sections with sustained, accurate suppressive fire, compared to 30-round magazines that are also compatible.
