Brocock TAC pistol at AOA

so I actually do know a bit about what you are saying..on my revolver it was a actual firearm except for the smaller barrel bore, and turned out cylinder, and one other important detail, the firing pin is squared on the end.. so a special firing pin that was flat on the end to depress the valve on the cartridges..
I think for prevention of what actually happened it could have all been prevented of they would have been satisfied with having the side turned out.. because to convert that you would have to replace the revolving chamber and the time the new one..
so the way that the crime was committed was to use a revolver that didn't have the side turned out and replaced the firing pin with a round one and a larger barrel bore.. they actually did the barrel when they made the illegal firearms out of them by just crudely drilling it out.
the criminal didn't care about accuracy, just about breaking the law.. it seems to me that brocock could have gotten back to turning the sides out like mine and been ok . but everything got out of hand and then it was too late.
I posted some more pictures.. I'll have to double check, I'm not sure if I posted the end field rifle,I think it was called but it used a larger cartridge and had more power..
I'll try to check back through the pictures..
I didn't understand what you meant by fafo but I assume that you meant something about the conversion process..
I'm definitely not interested in converting air to powder.. but I have given it a lot of thought about getting ahold of a cartridge somehow and converting firearms into airguns permanently making them airguns.. so to explain on a lever action you could easily bore view holes in the side of the action similar to turning out the side of the cylinder and the then it wouldn't be practical for it to ever fire gunpowder cartridges again..
plus it would be rebarreled to 177 or 22 caliber.

Thank you for sharing your knowledge on this. I will definitely reach out to you with questions after I’ve spent some time with it. The BACS/TACS system was a fascinating innovation in airgun technology. It definitely seems like the uses could be expanded on. Can’t wait to try it out.

please do contact me when you get it and if you need anything as far as resealing cartridges..
remember to silicone oil or silicone grease on the exhaust valve o ring..
you PM me and I'll send you my number so you can text me direct..
I was short on money otherwise I probably would have tried to get it and see if I could find a CNC machine shop that would make the cartridge parts..
but it's more than I am up to currently..
I'm really glad you got it.

There's one on ebay right now. It's a Uberti Colt SAA copy with Brocock name on it. I would love to have one, but the cartridges are probably very hard to find and expensive, then the hassle of airing them up one at a time, etc. Just not worth the hassle to me. Still, they are interesting.

UPDATE: the ebay one sold for $771, pretty cool!

yes they are very interesting and collectors items as you saw the price of the uberti on eBay..
the cartridges are the catch.. there's only so many of them around, being all brass and stainless steel I doubt they will go bad..
I still keep thinking about getting ahold of a cartridge and trying to find a CNC machine shop to produce the parts.. they are realitively simple design and only one of the o rings are hard to install.. you need a tapered hat and silicone grease, then it's somewhat easy.
would be great to see more added to this thread and even better if someone knows how to add links to the other threads about them here..
