Sheridan realised the sales opportunities of paintball very early on. Their first offering in 1985 was a bolt action paintball marker based on the action of their successful air rifle the Blue Streak. Now there does seem to be a bit of confusion about Sheridan’s early paintball markers but I believe that this particular example is an early K1 and not a later K2 bolt action paintball marker.
The K1 uses dual Co2 cartridges like this example. Whereas the K2 uses a single Co2 cartridge. Like all of Sheridan’s early paintball markers this one is made of a brass alloy and is part of what is often referred to as the brass era of paintball markers.
The other feature of this marker is the magazine. To feed a paintball into the breech when the marker is re-cocked the barrel must be tipped up to allow the magazine to feed. This style of magazine is still popular today in stock class play. However, these early bolt action markers were soon replaced with the pump action KP2 and then the gravity feed KP3 paintball markers.
