Hey guys, I'll be looking into ordering the parts for my g36e DMR soon, and have a question on battery voltage. Should I go with a 9.6v batter to use a high torque motor, or will the 8.4v batteries I have already work good enough? Also, what would the benefits of swapping up to a 9.6v be for a DMR? (RoF doesn't mean anything since I'll be locked into Semi-auto)

And, here are the parts that are worth mentioning and I would like feedback on:

Guarder Poly carbonate Piston - http://www.evike.com/product_info.php?products_id=26499

JBU Aluminum Piston & Cylinder Head Set - http://www.evike.com/product_info.php?products_id=28190
Guarder Infinite Torque-Up Gear Set - http://www.evike.com/product_info.php?products_id=27212
G&G High Torque Airsoft AEG Motor - http://www.evike.com/product_info.php?products_id=29937
- I've changed these out for a Madbull 7 metal tooth piston, Guarder Piston and Cylinder Head, G&P m160 motor & SHS gears, although I don't know what ratio yet.

Guarder Super Lucid Chromium Plating Cylinder - http://www.evike.com/product_info.php?products_id=25869 - Purchased and it seems like it will work great. Nice polish and great air seal with the other Guarder items.

Also, what spring should I be looking at to achieve about 500-525 FPS (After the spring settles) with a 500mm barrel and a properly padded piston head and AOE? Some people say that the sorbo padding will reduce FPS because you lose cylinder volume, while others say it will increase FPS by compressing the spring. I'm currently looking at either a Prometheus M135, Systema M150 or Systema M160 and would like to avoid ordering multiple springs.

It seems like your just trying to throw money at it, which won't work. The gears and motor will just be a waste of money as well as the piston. There's nothing wrong with the stock parts, you should see what you have in the gun first, and then order parts.

I will open it up and take a look at it, but I'm skeptical that stock JG gears and motors can take an m150 or m160 spring. I also doubt that both the gears and motor will be high torque, although I may go with a standard gear ratio to keep trigger response decent.

And even if the stock parts could handle it, something tells me I'll be replacing them quickly.

If you get one of the JG Red or Neo blues you'll be fine, as well as the gears. Pistons can take abuse along with the heads. If your replacing them quickly, your doing something wrong.

I'll see what I've got in there, but I just want to avoid catastrophic gearbox failures as much as possible. I've heard good things about the JG stock motors, but as far as gears go I'm not convinced they'll handle the spring. If anything, I'd prefer that my gears are high quality so the piston is more likely to fail first.

As far as the piston goes, I'm mostly ordering that in case I screw up the AOE and sand down a tooth too much, I've got a few other parts in my cart for that purpose as well, like a spare tappet plate.

I have had great luck with stock JG gears using a 150 sp. If shimmed correctly they should last a long time as long as you are limiting your fire rate to single shot only. If you have a 150 and are burst firing then the chance for breakdown is a lot greater and high torque gears with a different tooth ratio should be considered mandatoryIn my opinion the weakest link will be the pinion gear on the motor and should be a high quality aftermarket one, I prefer deep fire pinion gears personally.

As far as the initiall question the higher the voltage the better so a 9.6 in conjuction with a high torque motor should work fine. I personally wont drop below a 11.1 20c lipo for my DMR as that has yielded me very successful results

Okay, well I'll toss the Reinforced JG gears off Evike into my cart then. I'm fairly certain my rifle is pre-2008 and doesn't have the new gears in them. But I will go with a new motor and that deep fire pinion gear, which I'm assuming I could find on Airsoft Atlanta or Airsoft Extreme?

Okay awesome, and lipo is not something am very fond of so I'll just go with a 9.6v.

I don't mind having a slower setup if I use a mosfet which allows for pre-cocking. Plus with slower setups it forces you to think about what you're doing rather then pulling the trigger and throwing bbs down range.

ehobby and redwolf I know both have the deep fire pinion gear
I managed to find them and a whole host of Deep-Fire stuff on ArmorytechAirsoft which shouldn't kill me in shipping for a single item. Would you recommend any other Deep-Fire items or just the pinion gear?

Also, one of the reasons people like high ROF setups in DMRs is for the trigger response in semi-auto.

I don't care for trigger response TBH and ROF doesn't mean much since my gun wouldn't be field legal if it was 500 fps & full auto. At the end of the day, I'm sure that even with a high torque motor and standard mosfet installed I'll still get better response that what I have now while running a 8.4v.

And I like what goldentrigun has to say about it. I'd like to think about my shots and plan them out rather than spew BB's hoping to get a hit (Which is what I do right now because my gun is just bad. Real bad)

I am currently using a deepfire piston for my helical gears. The build quality on the piston is excellent too compared to other pistons I've seen with full metal racks.

I've also heard great things about their tightbores and gears. Although I can't speak for end range accuracy.

I'll look into it. Thinking about it, I kind of want to get a helical gear set to help with the heavy spring, so I'll look at their gears.

As far as barrels go I'll probably swap my Angel Custom 6.01 for a Promy 6.03 since 1. I'm not liking the AC and 2. I know for sure that I'll get getting what I paid for with a Promy. I did notice Deep Fire has 6.02 barrels, but I can't afford to test out one with $40 right now.

Deepfire doesn't make helical gears from everything that I've seen. Also, don't be fooled by "super high awesome infinity" gears unless you want the greatest durability possible while maintaining a stock motor as they absolutely kill trigger response. To the point where it is easy to half cock a piston if you aren't paying much attention.

If you want to see what I run in my spr look here. This might give you a few ideas although I wouldn't go with systema like I did for the gears. I got them for a steal which is why I have them in my gun.

Of course, I definitely have realized that the Guarder gears I was originally looking at just won't work very well. One guy on Evike said they ran on the large side and I don't want a ratio much higher than 18:1 and coincidentally, the Guarder gears don't mention what ratio they are.

I like that set-up for your internals, and I wish I could afford the Systema gears lmao. Also, that's a sick looking gun.

I've heard good things from SHS gears on budget builds. I'm not sure the amount of money you have budgeted so I'm not quite sure what I should suggest to you which would fall under your price range. Although $20 for a set of gears is a great price if all the hype is true.

Also, look at what color your JG motor shell is. Some of them have neodymium magnets in them which will be more then sufficient to run any setup that you throw at it. (as stated earlier. We're still in the dark at what your setup currently has.)

edit: referring to deep fire products

Their pistons are great have the titanium toothed one in my dmr right now, as well as air nozzles I use the plastic opposed to aluminum ones as they are o-ringed for maximum airseal. I am a fan of their barrels as they are stainless steel which I prefer and they are affordable. I personally have only scene more acurate barrels like pdi and edgi but for the price they are very good. not the most accurate but I get 6-8 inch groupings at 200 ft with one of my type 96's that has a deepfire barrel in it.

Okay, well I'll consider some of those parts as options when I start placing together all my orders. And sorry that I haven't been able to tell you guys what the hell the stock parts in my gun are yet, I'll be cracking it open on Saturday / Sunday because I just don't have time at the moment.

Kind of frustrated though because I've managed to strip the threading on my outer barrel and need to replace it now... and possibly order a different can to boot since this Matrix one doesn't seem to thread well.

EDIT: Looking at the Deepfire Titanium Piston, is there any way to do an AOE adjustment on that without special tools? Because I'm fairly certain I don't have anything that could create a smooth surface if I tried to grind the 2nd to last tooth down.
