The bison airsoft company don't make a huge range of guns but what they do make is made very well. Every bison BB gun is powerful and very accurate and all or the range so far are spring powered guns.. The dragonov sniper is the most popular in the range and its the cheapest replica of this sniper rifle you will find anyware. We think bison are probably the most promising BB gun company at the moment and we can't wait for them to make more new guns. Also check out the new bison 101 with its shell eject system.
