DMR Build

[Pick]

So after looking at barrels and other Parts i seem to have complied a list that I do Believe will build a Nice DMR.

Body- Noveske M4, Full metal with RIS, Crane stock
Piston- System Super Core Piston
Barrel- Masamune 6.01mm Extreme Precision Inner Barrel for M16A2 / M14 (510mm)
Silencer/Barrel Extender-   King Arms Socom MK23 Silencer (Foam filled CCW)
Spring- G&G M150 Spring
Piston Head- Systema Aluminum piston head with bearings     
Spacers- Echo1 H nubs
Bucking- Prometheus Hop Up Bucking (Hard Type)
Motor- G&P M160 High Torque Motor (Long Type)
Gears- Modify Smooth 6mm Gear Set for Hi Torque (Not sure if it is a 6mm or 7mm Gearbox)
Wires- G&P Switch Assembly for Rear Wired M4/M16
Battery- Currently using a 9.6V 2200Mah, Not sure if i need to upgrade it or not
Bipod- not sure what it is but one i bought from gearbox
I am planning on using the rest of the stock internals.

Looking for suggestions/Advice/Would advise something better.

As for the batteries, If anyone suggests Lipo's Please drop a link to where i can find Crane stock Lipo's (airsoft GI don't have any)

and yes i also realize that this is gonna cost a pretty penny

Aluminum piston heads just add weight to your piston/piston head... and offer no strength benefit over a duracon or polycarb piston head.
When using a 150 in a version 2 gearbox, it would be wise to use something a little lighter like duracon instead of the metal piston heads... takes the energy contained in the piston down a little bit and reduces gearbox fatigue slightly.

If you're getting a g&p m160, you shouldn't need to use hi torque gears. They will only reduce your trigger response. I pull an m140 level spring, and can do so on an 8.4 volt 1100 mah stick battery with almost no trigger lag using standard ratio gears and the m160 motor. It's super efficient. ridiculously high torque motor = don't need hi torque gears.

As far as wiresets go, they're all about the same, but for the record, I prefer king arms wiresets... easier to cut/strip the motor connectors for installing the m160 (doesn't use standard motor connectors). Plus, the red plastic bits are just fancy looking. lol.

Batteries:

They're always out of stock, but good batteries.
Ebairsoft and ehobbyasia both have them sometimes as well. I'm sure there are other people that can help you out more with those... I use a full stock and gigantic lipos.

You shouldn't need one, but they're nice.

Also, just as a thought, you will want solid bushings. Sure bearings MIGHT work, and they might never break... but if they do, your gears will pay the price. It's not an appreciable difference in a semi-auto only gun to go to solid bushings instead of bearings.

As far as buckings go... unless you have a phobia of opening your gun far enough to swap the bucking every 25000 rounds, you won't need a hard type over something like a G&G Green.

LOLWUT?  Using high torque gears will IMPROVE your trigger response but may lower your ROF.  I also claim shenanigans on pulling an M140 with standard gears on that battery with no trigger lag.

Well i'm not really concerned about ROF since it will be a DMR on Semi only. i jus don't want stripped or blown up gears

hi torque gears would only improve your trigger response if your motor isn't putting out enough torque to turn at a decent speed on the standard ratio. If you have a good motor like the g&p m160, you shouldn't have problems.


For argument's sake:
If you would like to see my gun's performance with an 8.4 stick, you would have to let me use one (I just sold my last one). and I will gladly chrono the gun to verify it's fps between 450 and 470fps with .20's at the same time so you know that that is with the actual spring. But I suppose the term "no trigger lag" is a little much... but "negligible trigger lag" is what it is. It's less than the time it takes for most guns to fire... it takes a large amount of effort to pull the trigger and release before the gearbox has cycled, even with the AB on the mosfet.

I've had a set of Systema High Torques for over 6 years now.  The WEAKEST spring it's pulled is a Guarder SP140.  Most recently they have been pulling a MAG MS190 spring on 11.1v LiPo's.  Still work perfectly.

No, high torque gears will always improve your trigger response as they are decreasing the amount of torque the motor needs to put out in order to pull over the spring.  The more torque your motor has, the less you will notice but it's still decreasing the trigger response.  The gun either has trigger lag or it doesn't, your opinion on it doesn't change what it is.  You stated it has "no" trigger lag which is crap.  It might not be enough to bother you, but it's still there.  On my setup it's pulling a MS190 spring and I only need half a trigger pull (maybe a bit less) to cycle the gun.

So.....Regular Gears or Hi torque Gears?

So.....Regular Gears or Hi torque Gears?

Xavier says hi-torque.
I say standard ratio.

I doubt you will ever get us to agree. You probably won't notice much of a difference either way.

I noticed lol

.  I also claim shenanigans .

LoL Shenanigans*

In my experiance, a M160 motor + 20c lipo= instant trigger response. I run a Amp motor in my M150 dmr set up and it pulls the M150 back instantly. I also use matrix/aim torque up gears and I dont see how trigger response can get any faster then zt zt zt zt.(sound effect of gun).

Also in my experiance. As long as you get the instant trigger response your looking for witch is easily attainable by a good strong lipo, I wouldnt go witch hunting for witch are better. Go with High torque for better reliabilty.

As long as you buy a good lipo and run deans, trigger response will essentially be the same with both type of gears. How much faster can u get than instant?> SUPer SUper Instant?
