BR55 Battle Rifle

From AegisWiki

The BR55 Battle Rifle is a gas-operated, magazine-fed, mid-to-long range weapon capable of semi, burst, or automatic fire and was put into service by 2525 at Harvest. Due to difficult aiming caused by fully automatic fire, both variants have been restricted to three round bursts. It fires the M634 9.5x40mm X-HP-SAP round in three round bursts (or in fully automatic fashion as seen in Halo: Arms Race) from a 36 round magazine and has a scope with a 2x magnification. It does reasonable damage to enemies being able to kill most within a few bursts. Its accuracy and range are also reasonably high, being able to hit a target from medium to semi-long ranges.
