full auto mechanical trigger?

[Canuck]

Well, looking at the trigger setup on my brand new A-5, and the light blinds me... Ding Ding...

So, fully auto would be as easy as fastening the trigger slider in the full outward position, therefore keeping the sear from locking the bolt and firing pin, er... hammer from locking..

I know it sounds simple but I'm following the basics of a blowback firearm, were the "slide" and "firing pin" springs are ideal to keep the action working when the sear isn't catching the firing mechanism, so to speak.

Oh, anyone know where the c-3 from tippmann stands law wise, firearm includes explosive's to propell projectile's? or they relax because is can't get over 350 fps... lol

last but not least, greetz all, I waited till I owned an a5 to join

Welcome to the forum!

This has actually been brought up before. The fact is that it works, but there is no hopper that can keep up with the cycle rate. This method also results in the rear bolt and sear rapidly wearing.

Welcome to the forum/addiction. You have a long expensive modding road ahead of you since you JUST got your A5 and already are thinking up trigger mods hahaha. Pick up a R/T or egrip for the increased rof, and keep your mech trigger as a back up.

Again, welcome

[Canuck]

hehe, no modding, just the idea, and yes, since I am an engineer all the pieces would get machined from high grade steel, and if the cyclone is capable of 17 bps stock, finding a spring, or adjusting the velocity the bolt moves at is fairly simple, weigh it down, hehe

anyway, everytings just an idea to begin with :-)

and ya I figured it looks a bit too "tin can"ish internally to welcome that kinda friction

[kender]

The ATF has already provided tippmann with a letter that basically states that the C3 is NOT classified as a firearm........Now I can't wait until tippmann comes out with a blowback style propane marker. Several thousand shots from a 12gram-ish sized propane cartridge and the days of having to refill air or running out while playing will be a thing of the past.

What if you upgraded your cyclone (say, TechT mods) so that it could cyclone faster and therefore feed paint at a rate that could keep up.

Or, would the Qloader be able to do that?

I don't think anything would work that fast. The cycling rate would be stupid fast (not to mention unsafe).

Hmm. In that case, since the speed of the bolt return is determined by the drive spring, would a lower tension one help in reducing the otherwise ungodly cyclic rate?

I seem to recall that there was a spring kit of various tensions offered for the A5...possible?

A blowback can cycle up to around 45 BPS, which is way faster than any hopper can keep up with. I've seen 40 BPS on an ego, and that was the record for shooting paint.

On the older Tippmann SMG's(full auto), they made the rear bolt weigh a whole lot, which slowed it down. It cycled around 12 BPS IIRC. If you where to make a rear bolt from Stainless Steel, or some other heavy marterial, you might be able to lower it down to something more manageable. That's the only idea I've thought of besides putting a lot of friction on it, which would have (basically) the same effect as making the hammer heavier, but it would also chew up o-rings very fast.

EDIT: Also, you could make it where it has to blow back farther. That would work as well, but would require alot more custom machining.

Sure. At the cost of going to about 80fps. Also, none of the Trinity or Maddmann spring kits have anything with that low of a tension.
