I bought the King Arms COLT M16A4. It comes with a 7mm gearbox, which I've heard is great.

I have a few questions. I want the gun to be a DMR, so It's all about accuracy, consistency, compression, and power. Speed is irrelevant.

I plan to use either a Prommy 590mm or 550mm 6.03. is the bore up necessary?

Is there anything else that I need to upgrade, or do you suggest any other parts? I'm not on a budget, I'd like the best performance.

I don't know, I don't do AEGs. I do know that Siegetek gears are by far and away the best on the market though.

From what I have read, something around 20:1 is good, pair that with a Terminusx motor and you're good to go!

EDIT: Don't forget the Terminusx Bushings...hell, just buy every product you can from terminusx besides the gears (which you need from Seigetek).

I may start a similar project my self in a couple of months.
Yes RiotSC makes the best gears also I might be able to find and a MTHaynes gearbox which is by the far the best!

I don't know anything about AEGs as I never really liked them.

I think you would be better with something like 13:1 ratio gears and with a high torque motor you'll have a nice trigger response. Mine has 18:1 and I often jam my trigger because of bad trigger response time :(

Go with 455 and non-boreup. I had troubles getting good enough seal for a dmr in my kit.

Supershooter phead, shs cylinder, sorboed shs chead, and shs air nozzle is the way to go. Make sure to also round out the cylinder window. And fix air seal.

Those gears are crap. Go with siegetek 20:1

The spring guide and piston are overpriced and bad. Go with shs, and shs 15 tooth blue. Make sure to get aoe perfect.

14 awg wire from home depot, and a mystikal fet for the rewire. Plus an 11.1 30c lipo (turnigy) with deans.

Shs shims, arl, cutoff, and spring are also all better. A common mistake is that systema makes the best parts. Their only good thing is their buckings!

G&p motors are no good either. Terminusx, and terminus bushings and pinion too.

SHS-parts are primarily very very good in their price range and I would buy them too.
And remember, Low ratio gears= less torque and vice versa, so with highspeed gears-powerful spring set-ups you have to get the torque from the motor.
What Im saying is that high ratio gears are made so you can run a high spring with a normal motor, but with a better motor you dont need to change the gear-ratio.

Thanks for the replies, I'm really looking into all of this now, I've found a bunch of Gear ratios.
Which is the best for my setup?

http://clandestineairsoft.com/index.php?main_page=index&cPath=1_6_30_31
-40.91:1 Torque Plus
-27.5:1 Torque
-20.15:1 Balanced Dual sector
-20.8:1 Balanced
-14.09:1 Revolution
-10.44:1 Revolution

Okay, so Omega Motor. D or O pinion gear?

SHS Type 0 Grooved, or Smooth? They have different bores.

500mm Prommy 6.03 with R-hop

http://clandestineairsoft.com/index.php?main_page=index&cPath=1_6_18
Which sorbo thickness?

Is the king arms 7mm shell with terminus bushings good enough or should it be replaced?

SHS m150

Also, what's better the nylon 15 tooth piston or the Polycarb 15 tooth piston?

With an 11.1 and an shs torque, you can use the 20:1 or even 14:1. On jg blue im pulling m190 on 20:1s.

Omega motor comes with a great pinion.

Grooved cylinder type 0

That gb with terminus bushings is good, just radius window.

3/16 sorbo with a 1/2 L flat faucet rubber washer from home depot (to protect the soft sorbo) is what i use. Just superglue it straight on.

Will more torque affect fps and consistency? I think I'd rather have a higher gear ratio than the low because I'm mainly going to be using Semi, and heavy springs. Rate of Fire isn't important to me, and I actually can't stand an ROF That's ridiculously high. 20 BBs p/s Is as fast as I'd like any gun I'd prefer a little less. Real steel M16s are like 15 RPS.

If its a dmr, youre using semi only. I recommend the lower gear rate for better trigger response. While the 48:1s might put little stress on your motor, there may be lag from trigger pull to shot fire. And with an omega on 11.1, you COULD pull a 150 on 10.1, although expect the motor to get very hot because of the amp draw...... lol

Yeah, I'm going for the Terminusx Omega. A few more questions, If I buy a Inner barrel with pre-installed R-Hop, do I also need to buy the M-nub?

And can someone recommend another good Cylinder? The SHS is sold out everywhere that ships to the US, and I've found like 5 sites that don't ship to the US.

I second the 14:1s, especially for omega on 11.1

The mnub is a good idea if you dont have the tools to make your own.

Honestly, most aeg cylinders are the same when polished, only differing mostly with the porting (and sometimes boreup). Any chrome plated (or even brass if you polish it) cylinder will work. If you pay more than $10 for one youre wasting money.
