Why not make a lower pressure mag?

[MadPSIence]

I know this has been bought up before, but for different reasons. Lower pressure in a mag would indeed help the efficiency a little but I think it could also solve a lot of leaks and other problems people are having. Springs in valves and so on wouldn't need so much maintenance and replacing if the gun took lower pressure. Because of the high pressure, things are so much more likely to leak or crap out when they get a little older.

It can't be too hard to make a kit to lower the pressure so why has nobody tried? I think the comp air kit for Tippmann A-5's is a marvel.. it's a little big and could use some re-design ergonomically but works great.

I'd kill for a mag that runs at 400 psi.

Your mag does run at 400 PSI.

so knock it down to 150. whatever pressure they run at now is wrecking parts.

for how simplistic they are we shouldn't be dealing with leaks.

I can't remember the last time an A-5 leaked.. (without someone tampering beforehand)

[AGDlover]

what about running a LP spring behind the piston like on adjustable tank to bring down PSI?

[Duck Hunt]

You're trying to compare an A-5 to a Mag...

An A-5 or 98Custom is just a blow back...A hammer smacks the valve and pushes it open, sending air down the power tube. The RT Valve is a whooole 'nother story.

You call it inefficient, but you only mean shots per tank. The Valve is tiny, is ANTI CHOP and recharges like CRAZY because its higher pressure. Low pressure is a myth, don't buy into it.

shots per tank DOES mean something you know. I can't stand that I barely get a hopper and 3 pods out of a 70/3000 fill.

FYI A-5's don't chop either so I'm thinking it's worth comparing the 2. I can fire crap like Predator paint, though an A-5 with a STOCK mis-matched barrel all day and not chop. Give or take some barrel chops though.. stock sucks

Break in the oring, then BAM. No more leaks. I don't have any leaks with a broken in oring and I live in New England, craziest weather in the US. Mags don't leak all the time, unless someone doesn't know what they're doing.

The lower your pressure is, the bigger the space it needs to move something. Look at Dye Matrixes, specifically the DM3. 2 of my buddies shoot these and they're supposedly "more efficient" because they're lower pressure BUT, they get about 1000 shots. So do I! Off a 68/45 too.

If you want more shots per tank, sell your 70/3000, and save up the 119MSRP for the Tippmann LP System and buy a tank in 4500PSI. Someone already tried to make a LP mag, it was smart parts, and they have no idea what they're doing.

Now if you want a REALLY LP gun that works, buy AKA. Vikings and Excals are unbelievably air efficient.

I have toyed with the idea of making a large chamber behind the bolt - in the valve assembly and doing away with the regulator portion, then running a regulator as a foregrip. The problem that I have come across in considering this is recharge rate - a larger chamber at lower pressure will take more time to recharge then the small chamber at high pressure.

[MadPSIence]

but if it can still recharge, say 16-17 bps on a mag then you're fine. Nobody will shoot that on a mech anyways.

[triggerhappy1]

Yeah mags are LP like they said. 375psi-400psi. But it will still cycle above 65psi like when your almost out of air. A lower operating pressure would mean a much slower recharge.

I have not had to replace a single o-ring yet. I bought my Classic heavily used, and after 5000+ shots from me still never a leak or bad o-ring although I do run carefull frequent maintenace. Mag internals dont wear out very easily or frequently.

Of all people, SmartParts made a "low pressure" kit for the mag years back. A few names it has been called are the "smartbox", "blackbox", and the "magicbox".
It added chamber volume, and thus you HAD to lower your pressure to get the velocity back down to below 300fps.
Ever heard of it? maybe. Still see them around? no. They didn't work as well as planned... and ugly as poo.

Guess what? Centerflag also came out with a Hypermag modified automag. It was a spacer inserted into the chamber to DECREASE the volume, thus forcing you to crank the pressure UP to get your velocity back up to 300fps. did it work? supposedly it helped with efficiency. Didn't live due to making a "high pressure" mag even higher pressure.. bad bad!

That's strange. I get 4-6 pods off a 68/3000 (68/45 with 3000 fill)

[Pyroboy597]

I get 700 shots off a 68/4500

[oldsoldier]

A-5's chop. I own one. I have yet to have a gun that doesnt chop. High pressure doesnt translate to poorer effiency. Look at the old school shocker (even the new ones). Those are LP guns...from a 68/45, you'd be lucky to get 4 pods and a hopper. There has been alot of research doen on the "myth" of LP. Check here, warpig, PBN, etc.
