Home made Sydarm, performance questions

[Beowulfs_Ghost]

I'm looking into making a haome made Sydarm. Basically I'm going to get a Automag classic, machine a ULE style body that will take PT Extreme clips (10rd spring fed).

Right now, I use 2 Core ZX (aka Zeus) pistols. I have them tuned to get about 12 - 20 shots on a 12g, depending on how fast I fire. I gets pretty good accuracy for a 7" barrel, about a 6" spread at 50'. Would a classic Automag, running of a 12g and an 8" barrel give my similar (hopefully better) performance?

I've been reading everything I can find about the Sydarm, and have noticed that many people mention a problem with liquid CO2, mostly with erratic velocity. Is this a problem all the time, or only under certain circumstances (ie high rate of fire, cold weather, etc).

I've also heard that the Palmer Stabilizer is pretty good at keeping out liquid CO2. Has any one here had any experience with using a Stabilizer and CO2 on a mag? Would it make sense to remove the internal reg, and just use the Stabilizer, or would using both be better? Would mounting the 12g changer horizontaly on the bottom of the grip, and running 8" of hose be enough to keep out liquid?

Also, would a lvl 10 valve help or hinder performance? I don't really fire fast enough for chopping to be a problem.

thanks

I don't think you should put a lvl x on it. Waste of money and gas in my opinion. I've thought many times that mags would be the perfect markers to make into sidearms, seeing as the breech is so far back. the Palmer's is very good at keeping liquid out; regulates as well as it has a builtin x-chamber. However, I don't think you want to remove the stock regulator. And you really don't need a second regulator anyway. I would just use an expansion chamber to keep the liquid co2 out. They're not that great, but one will help.

I'm pretty sure you can't remove the internal regulator. It's built in to the valve.

My guess is that an 8" hose will keep out the liquid, as long as your not unloading as fast as you can pull the trigger.

I'm not too sure on the gas efficiency question, but I know Mags are known to be a bit of a gas hog. That effect is greater with the level 10, so definitely don't install one.

Another thing to consider about the Palmer Stab is the internal volume. How much of a 12g are you going to use just gassing the marker up? I'd check on Pump players forum (maybe the Phantom Online Group or Stockclasspaintball.com) about the feasibility of 12grams w/Stabs. I read awhile ago on one of those forums that the better solution was a Sherdian RG-1 regulator if you're going the 12gram route.

She gets about 10-12 good shots off a 12g but if your rapid firing she freezes up quick

That's basicaly what I'm look at doing. Except the clip and ASA will point the way.

In most situation for me, "rapid fire" is a quick string of 3 balls. Will it freeze up in 3 rounds, or do you have to empty the whole clip to do that?

Comparing the Automag to my Core pistols, the breech is farther back (by about 2") on the Core. So, with the same barrel length the mag would make a longer pistol. On the other hand, the Core is basicaly a Spyder with a funny bolt, which makes it pretty tall (stacked tube w/ clip). So a mag pistol would be about 3 inches longer overall, but not as "tall" as the Core.

Has anyone tried this with a MiniMag body using a vert mounted 12g quick changer? I'd be interested to see how that performs.

A three round burst is usually fine. Trying to rip through all ten almost certainly freezes her up.

ghideon,
I use a vert 12g setup on my pump minimag with the same efficiency

Is CO2, in general, bad for the internals? Would I need to take better care of things (more cleaning, more frequent rebuilds) running a mag on 12 grams?

[Chronobreak]

yes theoretically but its just the dirt in the gas its not like every game ur gona have to rebuild it classic amgs are generally fine on co2

[Drizit]

i run my phantom off 12 grams and there's no problem, i can't tell you for sure what a mag would be like as I've never put mine on 12gs and all the bulk CO up here is food grade and the 12gs are industrial grade (ie more crap in the gas) but i find when you oil them through the asa lots of crap will come out on the rag you put over the breach, just be generous with the amount of oil you use at the end of the day, and try not to let her sit without being cleaned up, as to rebuilds i don't think it will relay be much worse then running it any other way. depending on how much you use it just replace all the orings ones a season or something.
