The M24 Sniper Weapon System—SWS—was a variant of the Remington Model 700 rifle. This weapon is categorized as the military and police version. It is commonly referred to as a "weapon system" because the M24 allows for a detachable telescopic sight and other accessories in addition to the rifle itself. The M24 is a bolt-action sniper rifle, firing 7.62 x 51 mm NATO rounds with an effective range of 800 meters.
What Tang Ziyi and Ling Qingyu had chosen was a completely modernized version of the old 20th-century M24, with an almost unrecognizable futuristic scope, tiny Piggytinny rails, an adjustable buttstock, and a modified magazine holding 10 rounds.
Currently, M110 semi-automatic sniper rifles were preferred over the M24 in Country A's military, but Tang Ziyi liked the good old, venerable M24. It was reliable enough to get the job done. The old generation always fended just fine.
