A good hop up, a good bucking, a good barrel, and a general knowledge of how to make it all work are far far better for accuracy then either a Polarstar or a Mechbox. Both are designed to push X amount of air down a tube, both work. The correct size tube, and fps, helps a lot.
The PS makes it easier to play with FPS, but you have to add a bunch of equipment to make it work, the Mechbox makes adjusting FPS more difficult, but is more compact. A bolt action spring rifle is tiny and powerful...ect
Do you want to carry a battery, 4ft of hose and a high pressure air tank? Ok, get a Polar star system.
Do you want to carry a battery and have to be able to work on a Gearbox? Ok, use a mechbox.
Push that air, down that tube.
I somewhat agree with that. But the polarstar doesnt only make it easy to play with FPS, it also makes it easy to fine tune the exact amount of air running down the barrel behind the bb, and also , very key, it allows closed bolt shooting which no aeg other than the PSG1 can do. It chambers a BB, lets it seat, and waits for you to fire the trigger before shooting air down the barrel.
In CB mode I can send BB's over 100 yards with fair predictability. I haven't had a chance to fine tune things much beyond that at the moment, but farther accurately is definitely possible, I just haven't had time to tweak my rifle for distances further than that.
In tweaking AEG's to get the same accuracy @ the same FPS as a P*, with the same reliability, you will likely end up spending the same amount in the end, but you will still be stuck with a gun at a fixed fps, and be in for a world of tweaking again if you need to change its fps for a given game.
I like being able to take the same gun, and for one game, set the fps @ 350fps with rof of 60 bb/sec on 5 round bursts for an cqb games at MTT, then set it to 375fps for outdoor games at a rof of 10 bb/sec and set my rifle up as a light machine gun which just lays down slow burping suppressive fire, then set my rifle for 620fps single shot mode when I put in low cap mags and my ghillie suit for stalking around.
All of this with the same rifle, with changing no internal parts. I use the red nozzle at all times and am able to get from 300 fps to 620fps and between single shot to 3600 bbs per minute with only changing regulator and computer settings and nothing internal is ever touched.
I still love aegs, I just bought a new TM scar, but even it doesn't measure up to the flexibility of the fusion engine. The wiring is a weak point, but its easily fixed with smart wiring of the gun.
