metal toothed piston vs plastic tooth piston
« on: August 23, 2010, 07:13:58 PM »
OK so I'm just pricing out a new set of internals for a project gun. Is it worth the money going with a metal toothed piston or not? Also has anyone had experience with padded piston heads? Do they change the fps or any other affects. What are the pros and cons of each?

depends on what your goals for the gun are.

I always favor plastic pistons. I would prefer shredding one of those rather than a nice set of gears. Also, they are lighter weight and easier to modify.

Although I haven't done much gearbox work, my spidy sense tells me...........what he said^
While metal teeth on a piston may last longer, now it is going to cause wear on the gears. Plastic teeth would cause little to no wear.

Project guns are so fun. :P

My gun shoots around 380-400 fps with .2s (haven't gotten it chronoed in a while) at 23-24 rps and I'm only using an Element clear piston.  http://www.youtube.com/watch?v=WfjsE99eOrM

Piston has been holding up fine for a while now.  If you are running a moderate set up (M120 spring, at around 25 rps) you really don't need a very strong piston.  Just remove the 2nd tooth and adjust the AOE.  Once you start getting into high speed or high fps set ups (or a mix of both) you are going to want a piston with quite a few metal teeth.  

Something similar to this:

The king arms POM piston is a very lightweight piston that deals with high fps well, but high fps tolerant pistons aren't good in high rof systems.

The element pistons with 1 metal teeth will take mildly high fps (up to 400 or so reliably, and up to 450-500 for 5-10k rounds) and high rof. I like them for most guns... cheap and reliable.

Of course, if you just want a piston you never have to worry about failing unless you set up your gearbox poorly, the system supercore is supposed to be the bee's knees.

A good Poly. piston would be just fine Area 1000 is a decent starter but if you have money go for the Systema Super Core Piston 'tis a Beast

You mean the System (without an A) Supercore? Like the one that was mentioned in my post less than an inch above yours?

I put this piston in my M16 because I had torn the teeth (in one case it was all the teeth) off four regular pistons in a row.

Sounds like a problem with your AOE, not necessarily a cheap piston. That, or you are running too much power for a "regular piston"

By regular piston, I mean a polycarb body piston with polycarb teeth. The four I tore apart were Systema, CA, Mad Bull, and Area 1000 (which I think is also Systema).

My M16 uses a Systema M120 complete gearbox, Systema magnum motor, and a 9.6v 4200mah battery.

Well that would do it...lol  

Magnums are serious motors.  If you don't adjust the AOE and you are using a magnum motor with a high discharge 9.6v battery, it will rip pistons up.  I'm guessing your ROF is around 25+ rps?

I haven't measured the ROF but it shoots fast. It looks like a laser beam when I use my tracer unit.
