The BAS-1 (Bolt Action Sniper One) is a sniper rifle developed by Down Inc. that is chambered in .338 Lapua and fires from 6 round single stacked mags. When designing it, down looked at the Accuracy International L115A3 AWM for design ideas, such as the thumb hole stock and all-polymer frame. It has since been adopted as the standard sniper rifle of the UPM.
