Double barrel, single trigger, mechanical frame, alternating fire questions...

[DavidBoren]

I am curious how to go about achieving alternating firing with a double barrel blowback marker.

Getting them to fire in parallel would be easier, certainly. And I am not even sure it is possible to make them fire in series without adding pneumatics. I was thinking it might be feasible to set them up with pneumatics to pretty much fire like a RT/SPAR trigger, firing one on pull, the other on release... but they're freaking Stingrays! Lol.

So, any purely mechanical options for alternating fire between two barrels? And by barrels I, of course, mean complete upper assemblies.

There might be a way to offset the sears, but one barrel would always fire first, then the second. So a short pull would fire the first, finishing the pull would fire the second.

That would probably be better from a safety standpoint.

Seems like a Jordan question. I'm guessing something with the sears? Maybe some kind of cam to activate each sear or RT piston separately?

Can't remember the stinkray for the life of me. I remember lots of bars, plastic, and soft metal. But, tooless disassembly!

We gutted the valve body and used it as an instant beer chiller. We'd fill a bucket with beers and then crank a 9oz C02 on the stingray so it dumped out the barrel into the bucket like a fire extinguisher.

I literally just bought another one. Lol. Stingrays have been a favorite of mine since I started playing (1998?), and I have accidentally accumulated a small fever of the things. So now, naturally, it's time to tinker... maybe they are like Voltron and get bettdr the more you hook together...? We will never know unless we try. And, if all else fails, I will be able to chill TWICE as much beer (or the same amount twice as fast?).

A rotating sear link would be interesting, almost like an escape wheel on a watch. That way, even slow single shots would alternate instead of always being one gun first.

Similar to the burst mechanism in an M-4 trigger group? Staring at pictures of watch mechanisms on my lunch break isn't really inspiring anything right meow... more research will be required...
