CA m4 can't pull m130

[incrediboy729]

Hello.
I recently bought an m130 spring for my Classic Army M15a4. It can only pull it back about 4/5's of the way before stopping. Everything is installed correctly and shimmed correctly (and my stock spring works fine after reinstalling it.), and I have to (with just the lower reciever on) "help" it pull it back by reaching and pulling the piston back with 2 fingers. I am running a 9.6v 1200mah ni-mh battery. So does this mean i need torque up gears? Should I get double or single torque?
Thanks alot for you help.

Is your battery AA cells? If so, it won't be able to pull that spring. Also, CA motors generally aren't the best.

Are you using a mini battery or a nunchuck style battery? Those are made of smaller cells that usually have a bit of difficulty achieving enough discharge rate to pull that kind of spring. If possible, you may want to consider switching to a different battery system that can accommodate a larger battery. My ICS M4 had trouble pulling an M120 with smaller batteries.

As a side note, I'm sure you're aware of the strain an M130 is going to put on your mechbox and the FPS limits where you intend to play? An M130 is going to fetch you in excess of 420 FPS.

Yes i know about field FPS limits, i'm not a gamer whatsoever just a plinker. My battery is a "brick" (as in ====) normal type 2/3a cell mini type battery.
Yes I am aware of the strain and will be buying a systema silent piston head followed by a new piston. I'm not just gonna leave it stock and m130 .

EDIT:
I agree that a bigger battery might pull that spring, but wouldn't torque up gears be easier on everything? I mean throwing more power into the motor would cause motor stress, gear stress (from normal gears pulling an m130) where as it would be just as cheap to buy torque up gears resulting in less gear stress (not to mention getting upgraded gears which enables more powerful motor and such) and less motor stress? I mean pulling an m130 it would be nice to have strong aftermarket (systema probably) gears anyways. And btw I will NOT be firing on full-auto. Agree?

Do you have a bearing spring guide and bearings behind the piston head??? If so, remove the bearings from piston head and re-assemble. Should work fine.I also agree with goin for torque up gears for any spring over a 110. They'll last longer but, I don't think it'll relieve the stress on the motor.

Super Torque up that gear, switch to TM EG1K and 10.8v battery. Problem solved.

No I do not but thanks anyways.

Yes you did help very much in that thread and along with crunchmeister helped me decide:
A: Not to go with the JBU upgrade kit.
B: That I don't need a reinforced mechbox for now
C: Crunchmeister helped me decide to go with an m130 and Systema silent piston head
But Crunchmeister didn't say that my CA COULDN'T push the m130 therefore i decided to start a new thread.
The last thing i want you to think is that your help went nneeeooowww (over the head noise) and i blew it off. 100% not true. And i appreciate everything you've helped with.

So i need the super torque, not regular torque? Gotcha thanks a bunches.

And thanks to everyone who has helped me so much through my ordeal.

Definitely you need a STU gearset and a question for you. What CA Ver.2 gearbox are you using 6mm or 7mm bearing bushing? If it is 7mm bearing bushing I advice you to change that to 7mm metal bushing.

TM EG700 has more torque, and would be a better choice.

Agreed. on the EG700 motor there bro... and STU gears are not manditory, but some type of TU gears are definitly required. As well, ditch any ball bearing bushings, go solid oilless metal as stated above.

Ran my TM AUG with a set of Systema level 2 torque up gears, with an M130 spring, and a 2400 mah battery (mounted externally) with no problems.

They are the stock bushings and from what i've seen inside the mechbox (i haven't taken out the bushings but have seen them from both sides) they don't look like bearing bushings. And to my knowledge they are 6mm. Thanks.

I don't really have easy access to an EG700 but after i get new gears and possible a new piston i should be able to run a systema magnum, no?

How did you mount it extenally? PEQ? What size are your battery cells? Also I haven't heard on "level 2" or any "level" of torque on systema, all i've seen is "torque up" "super torque up" or of course "standard ratio". What is you level 2 equivalent to in those options?

A Systema Magnum is a bit of overkill... I mean you're plinking with this thing. If you want to invest that much money into something that won't even be gamed, then a Systema Magnum is probably as good as it gets.

It's totally not that i'm not listening to you guys but a TM EG700 just isn't availible to me. So what about this?
http://www.airsoftgi.com/product_inf...oducts_id=3566
And if the answer is yes then are we all agreed on
http://www.airsoftgi.com/product_inf...roducts_id=648
Then:
http://www.airsoftgi.com/product_inf...roducts_id=770
Then:
http://www.airsoftgi.com/product_inf...oducts_id=1431 (or some form of aftermarked piston)
Then:
http://www.airsoftgi.com/product_inf...oducts_id=3566
Or maybe if i'm still having trouble getting my CA to pull it the magnum will come somewhere earlier in the list.
Thanks so much for all your help so far!

Since you are in the US and airsoft is cheaper there compared to us.

Systema Flat Super Torque up Gearset, Systema Silent head set, and either Prometheus Hard Piston, Deepfire Full metal Teeth piston and Supercore (This is the best in the market out today)

For motor.
G&P M140 or M160 motor(Alternative to expensive Systema Motor)
