Bison's men appear to armed with the M4A1 carbine. Some of these rifles have fixed stocks and some have collapsible stocks.
Heckler & Koch HK33
What appear to be Heckler & Koch HK33 rifles are used by Thai SWAT offiers. Believed to be HK33, because HK33s were built under license by Royal Thai Army Ordnance (HK33A2 as Type 11 rifle, HK33A3 (with adjustable telescopic stock) as Type 11A1 rifle and HK33KA3 as Type 11K carbine.) and have been used widely by LE and military units in Thailand (Where the film takes place). Also, by Thai firearm acts, it is illegal for the civilians to import or own the centrefire rifle that can be fire semi-automatically or automatically (without permission, which is, really hard to request). So the easier way may be chosen, by using the Royal Thai Army's or Royal Thai Police's rifles.
