If you could change the way mags operate...

[Surestick]

I've wondered about doing away with the sear & replacing the metal spring with an air spring or ram.
Firing would mean dumping the air holding the bolt back.
You would have almost no resistance to forward movement of the bolt & could make the lvl 10 super sensitive.
You'd need an LPR of course, it adds complexity and would waste air and give you another place for leaks to develope so it's probably a bad idea...

Efficiency and the fact that its a "sear tipper."

Please explain whats wrong with it being a sear tripper. Why is a sear inferior?

[eric_503]

you know how mags come stock with a carbine fiber single trigger why not make carbin fiber double trigger frames? not as expencive as the intelli but with the same looks (intelli's are like $90? so c/f like $50 or $60)

I think for some people it's a matter of having a part (sear) physically hold another part in obstruction to some motion, that it's an unprecise and perhaps blunt way of controlling the operation of the gun.

Personally, I'd like to mod a mag setup to function off two separate pneumatic pistons to take the place of the sear (one for the bolt and another for the shutoff), we brought it up in a different thread but the exact benefits are yet to be seen...

A mag is an already great platform to build on. All and all the marker isn't needing the major revamping, AGD itself could use a shake up. It is like the company itself has been castrated.

AGD should go beyond the TAC-ONE and throw an X-Valve into something like an AR-15 upper receiver. Rail? AR-15 lower receiver!

Perhaps I misphrased my point. I don't have anything against sears in general, I'm just stating that they have their disadvantages. They aren't universally reliable, for instance. A sear makes an abrasive metal-to-metal contact that is weared and grinded upon each time it moves. Sears don't obviously wear out too often, but when they do that's why.

But it depends on the situation (and what you were to replace the sear with, for example).

But the fact that firearms use them doesn't mean they're the glorious answer. If the benefits that a pneumatic valve brought to paintball guns could be applied in a firearm then it'd be used there too. Need I remind you that a firearm has to be used in a somewhat different application.

Personally, I'd take the simplicity of a piston shaft over that anytime. It doesn't even have to be controlled by electronics either, although that opens up an amount of its own possabilities.

Sears do the job with a simple and I will say again unprecise mechanical gun (please note I am not accusing all sear-driven markers as being unprecise) but there are other ways of doing the same jobs and in most cases it's a completely different setup. Apples and oranges, if you know what I mean.

I definitely think the sear use hits its peak in a mag though. Not all sear markers are created equal...lol

Pistons simple?

A cylinder, wear and seal points on the piston and shaft, connection points at cylinder and rod ends, air hoses, etc.

vs.

A sear with a catch and a pivot point.

And how exactly is a piston inherrently more precise? It just shoots from one end point to another. EXACTLY like a sear tripper marker does.

[Ydna]

I said more precise becuase you have an exact amount of force each time it's put into use. Not only that but you can easily measure the force as well.

Whereas a sear only holds back the movement and impedes it from firing until you release it. At that pointt he moving aprt in the marker is totally at the will of whatever driving force present. Fire a bolt forward and have it stay there for, oh, however long the air pushes on it. Know what I mean?

Look, I'm not trying to badmouth mags here. I love mags. I'm just trying to put forth reasons for some other ways of doing things. When it comes to simplicity a sear will obviously take the cake but my goals often involve other things that happen to shy away from springs and latches.

Markers without sears dont have wear points? Anything without a sear is just a more complicated way of accomplishing the same thing. I dont think there is a firing system out there yet that wont wear out eventually.

[SummaryJudgement]

I think everyone here is talking about the original RT design to some degree.....

At least as far as gas flow goes, or maybe I'm misreading things?
