Sheridan made a handful of paintball rifles back in the early 80's. Here's a short list, complete with some vintagerex.com links and pictures.
- bolt action stock class rifle.
- pump action stock class rifle
- pump action direct feed rifle
- pump action constant air direct feed rifle.
There were several other variations on this style of marker available. Some of the Brass Eagle Nightmares were available with an optional shoulder stock (not wood, but plastic or composite). Others were special limited-run or one-off creations made by skilled airsmiths (for example, some of the old RTP Vipers and consisted of Sheridan bodies and custom shoulder stocks). To my knowledge though, the only mass-produced
paintball marker line to come from the factory with a wooden shoulder stock was the Sheridan K-series.
Someone mentioned that these guns can sometimes go for as much as $600. Yes and no. As with any collector's item paintball gun, it depends on the age and availability of the item in question. K-2s are much harder to find so naturally they are worth a little more. Depending on the condition, you can get a KP2 or KP3 for between $250 (needs work) and $500 (near mint). The most expensive KP I've ever seen was a KP2-SC fully tuned and modified by Palmers Pursuit Shop. It was re-tuned, spring-fed, nickel plated, lazer engraved, and had a custom ported barrel. I think it sold for just under $1000. My personal KP2 is in decent condition, shoots fine with no leaks, and just recently had a rebuild from Masse's and a refinish job on the wooden stock. Its probably worth between $300 and $400 right now.
As for Palmer's, they can modify the old Sheridan rifles or custom-fit several of their guns (pump AND semi) to use a wooden stock. As several of you pointed out, they aren't cheap. But for Palmers quality work and craftsmanship what do you expect?
