Who designed the first stacked tube blowback?

[Meph]

Palmer made Camille back in around...... 1987-1988. It was at least one year after the Tippmann SMG-60 came out, I remember that. But Palmer never designed a STBB. That was Sheridan with their VM68. Palmer always dealt with Sheridan style markers yes, but usually always pumps or semi-automatic with a ram, 4-way, and LPR (yes 4-way, Palmer brought it into paintball. Bud just ripped it off and called it a 3-way because he had no clue what he was ripping off at the time!).

F1 came out just after the VM.

For a date of when the VM68 first came to be. Beats me. I keep forgetting. But I'm sure it was probably late 80's.

MarkM, lol, I said PMI-3, just going back to the time when the Automag hit the scene, I know it isn't a blow back, in fact it was the only non-blowback semi. Well.. I guess you could count that gun that some guy turned into a semi from a pump gun, hehehe

I had a standard barrel on my mag when I first got it, later got the crown point. AGD was always so cool about upgrading my mag for free as well.. they gave me a new bolt to replace the springed one and all kinds of level updates. The barrel I had to pay for.

It was nice.. back then a top of the line marker (mag) was $500... now it's $1000+. Shows that AGD was always fair in their pricing and didn't take advantage of everyone.

Ok nice dig at a 'cocker, sheesh you mag owners No way was it a cocker as I used one of the 1st generation when they came out, 4 good shots then 2 bad ...pause then 4 good then 2 bad and so on...good to see it got fixed.
I have a pic I took somewhere of a guy using a VM 68 (think thats what it is...bottle at the front like a precharged air rifle and a bottle at the back) but that pic predates the introduction of the auto cocker by around a year. At this time semi auto was banned in all major competitions in this country, so to own a semi was a little mad.

Wasn't the Promaster built by Line SI the fist of the stacked tube designs.

I think actually the Promaster is the exact specific marker that the Kingman Spyder was cloned from. Yes they're all the same, but specifically the Promaster is the model that Kingman knocked off.

It certainly seems like it! They look and operate almost identically.

Tipmann is credited with having the first semi auto/full auto paintball marker. The Tipmann series were all single tube designs.

The first stack tube design comes from the original Nelspot pistol with the ball magazine tube being directly over the hammer/spring tube (2 tubes total).

Benjamin Sheridan took that same two tube design and modified the top tube where the paint used to be stored and changed it into the breach by adding a bolt that was linked directly to the hammer assembly in the tube below it. A minor change to how the sear interacted with the hammer, and bingo, the first semi auto stack tube design.

PMI, acting as the distribution agent for Benjamin Sheridan, marketed the product as the PMI III. Later, when PMI discontinued the line (after a name change), Benjamin Sheridan then picked the line back up for a brief period.

The vernerable PMI III is the father of all the stack tube clones on the market today, very little has changed in most of those, bolt linked directly to the hammer assembly, spring forward/blow back design.

You can still order parts today from Benjamin Sheridan (at a premium) to service your old classic tank.
