Concept question...

[Inebriated]

Hey guys, I am just sitting here looking at some paintball parts I'm thinking of selling, and it reminded me to ask something. One of my paintball guns is a Tippmann 98. Some of you may know what it is, some may also know about the response trigger. If you don't, here's what it is... when you shoot, the bolt releases and hits a valve releasing CO2/N2 into the barrel, and into the bolt face, sending it back to catch the sear. Now the response trigger siphons off a little bit of that air, and sends it to a piston behind the trigger, which resets the trigger by force. But, since your finger is still pulling, you get another shot. You can accomplish upwards of 15 or so balls (shots) per second like this.

My question is, in a firearm, would this not constitute one shot per pull? You are, after all, engaging the sear every shot. I just though I would ask you gurus out there, and see what the deal is. I wouldn't ever want to try this with the hot gases of a bullet, but I have been wondering about the concept.

Thanks!

Similar concept.. just a different application of the physics (at least in my mind it's similar to what you're talking lol).

So, the paintball gun deliberately causes trigger slap in order to mimic full auto. Interesting.

I think it would be classified as naughty. It essentially fires full auto, almost using your finger like an auto sear. This is the argument basically used against the Atkin's Accelerator. The Slidefire is almost the same as the Atkins, except that the Atkins used a spring to push the action forwards instead of muscle tension.

I thought of that at first, and then decided to go ahead and ask lol. I mean, both are an outside force, and both require the bolt to catch.

Legally, how sound is my or the SlideFire's method? I've seen people saying it'll be illegal, but I don't know if that's just people being negative or if there's really anything going on with that.

Sort of. Like the SlideFire, it is controllable. You can easily override the return, and keep it semi. On the paintball gun, there's a valve that lets you adjust the pressure of the return gasses in the piston, so you can open it all the way and be unable to pull the trigger after your first shot, or close it completely to disabled it completely, or you can just pull harder and make it stay semi.

Write the ATF. Then you'll have your answer.

The thing about the Slidefire is that more user action is required than merely pulling the trigger. You have to pull the action forwards again, which appears to make some mysterious difference to the BATFE for whatever reason.

I don't think the adjustability of the valve matters. Like the Atkins, you would just pull the trigger and the gun does the rest of the work with your finger as an autosear, even though you are technically pulling the trigger for every shot.

It would be interesting to see if you could write them a clearly phrased letter and see if you can get a useful reply. The BATFE just makes it up as they go along whether it makes sense or not, so it's entirely possible that I might be mistaken.

The thing that sets the slidefire apart from the atkins and sw-sim (also why the atf has let it fly, so far) is that it ONLY uses user action. The fact that they frown on a spring would also put a damper on any pneumatic, hydraulic, centrifugal or fill in blank way of resetting the trigger that is not directly applied by the shooter.

The slidefire looks to my like it is just an easyer way to bump fire. I dont know about ARs but on an SKS this is very easy without any add on parts. Just pull the trigger into the trigger finger instead of the trigger finger into the trigger and boom full auto!
