Question upgrading a G&G M4 CQB-R advanced

I need some suggestions on how to upgrade my G&G M4 CQB-R advanced. It fires around 370 FPS, I would like to get it around 450, but no higher than that.

Here are the features the advanced version already has:

8mm Ball Bearing Bushings

G&G "Strong" Motor

Metal Ball Bearing Spring Guide

Reinforced Piston

Metal Piston Head

Silver Wiring

Silver Electroplated Tight Bore Barrel



Could really use the help. Kind of new to airsoft. Thanks.

I've seen sales sites saying it's 229mm like the mp5s
I forgot to check last time I had mine open but I think it's the same as the mp5s

and free bump for any new guys or gals doing research

Hey doramider7,

the 1mm from 300mm-229mm will not make much difference when you have put that into either your mp5 or AK beta. either length will be fine and shouldnt see the innerbarrel poking out the flash hider

Cheers,
Noc

Thanks for all the info...Very Cool!
Please dont razz about insane ROF's. I am just messin around.
I am putting in KA 13.1 High speed gears with a KA sector clip. If my calculations are correct, it should buzz about 1900 rpm/31 rps.
I cannot find any specs on Hornbill HS motors. So I am estimating 25000. 9.6v/1500 nimh batt.
Does this sound correct?

Posted here are collections of technical information from previous forum threads (FAS/AGL) and general facts from experienced veteran gunsmiths and players.


====================
- - Technical Reference Info - - (by skipperooo)
====================


SPRINGS: (Approx. Settled Spring FPS on .20gBB)
Stock Gun (brand new gun) = 270-290 FPS

CQB Gun: M100 / SP100 / PDI120% = 330-350 FPS - Typical indoor field maximum permitted.

Standard Field Gun: M120 / SP120 / PDI170% = 390-420 FPS [.20gBB stable] - Typical outdoor field maximum permitted. Anything stronger usually requires organizers permission.

Spring Power Chart http://www.airsoftcanada.com/SpringChart.html
BB goes wild = BB too light -- BB range seems near = BB too heavy

*NOTE* These indications are FAS FPS Regulations and are NOT ASC FPS Regulations.

- - - - -

GEARS: (Does NOT affect Gun FPS, only ROF)
Infinite=(1) Ultra=(2) SuperTorqueUp=(3) TorqueUp=(4) StockRatio=(5) FastGear=(6)

>> Numbers indicate "car-gear-shift". *Small batts (non Sub-C) DOWNSHIFT to next LOWER gear. <<

Common Gear-to-Spring Setup for Big Batt (engine) (Sub-C):

Fast Gears (6) - UP TO M100 / SP100 / PDI120%

Stock Gears (5) can 'safely' handle up to M130, SP130, PDI190% <<<< on 9.6v 1700mAh(min)

Torque Up Gears (4) - M130 / SP130 / PDI190%-210% or LOWER

Torque Up Gears OR Super Torque Up (4/3) - M140 / SP140 / PDI240%

Ultra Torque Up Gears (2) - M150 / SP150 / PDI270%

Ultra or Infinite Gears (2/1) - M160 / SP160 << Needs minor machining to fit on Ver.2 GearBox

Infinite Torque Up Gears (1) - M170 / SP170 << Needs minor machining to fit on Ver.2 GearBox

*Some Gear set won't fit on some reinforced Gearbox- PLEASE CHECK first before you get one.

*No known machining on stock ver.3 GearBox to fit any gear set.
*AVOID using Bearing Bushings on M120 above. only for soft springs

M130 / SP130 / PDI190%-PDI210% on STOCK Gears will last Approx. 5-10 months (depends on use)
Stock Gears - Low Cost, nice ROF. will not last long. (cast alloy)
Flat Gears - Noisier, Cheaper. More durable (steel)
Helical Gears - Silent. Expensive. shimming sensitive (steel) <<Avoid pairing w/ Bearing Bushings

- - - - -

BATTERY: (Does NOT affect Gun FPS, only ROF and Rounds of fire)
Voltage = Rate of Fire (ROF) mAh = BB-Rounds (Power/Stamina)

BIG INTERNAL Standard Battery Size [Ni-CAD]:
M4A1 - 9.6v 1700mAh (Fat-long AA) V-Type 12v 1700mAh(max)

M4A1 Patriot - 12v 1700mah (Fat-long AA) Circular config

AN/PEQ 2 Dummy Laser Box - 9.6v 1700mAh (w/laser) 12v 1700mAh(max)



Approx. Battery-to-Rounds Capacity: [NiCd] (on M120 Stock Gears, EG1000)

9.6v 600mAh = <500 rounds (Small) Sanyo KR600AE 9.5mOhm Internal Resistance

9.6v 1100mAh = 1,000 rounds (Slim) Sanyo KR1100AAU 19mOhm Internal Resistance

9.6v 1500mAh = 1,400 rounds (Fat AA) Sanyo KR1500AUL 16mOhm Internal Resistance

9.6v 1700mAh = 1,800 rounds (Fat-long AA) Sanyo KR1700AU 17mOhm Int. Resistance

9.6v 1900mAh = 2,400 rounds (Sub-C) Sanyo N-1900SCR 4mOhm Internal Resistance

9.6v 2000mAh = 2,600 rounds (Sub-C) Sanyo KR-CH 6.5mOhm Internal Resistance

9.6v 2400mAh = 3,100 rounds (Sub-C) Sanyo CP-2400SCR 4.5mOhm Internal Resistance

9.6v 3000mAh = 3,800 rounds (Sub-C) Sanyo HR-SCU [Ni-MH] 5.3mOhm Internal Resistance

*can someone confirm this rounds guesstimation--
BEST BUY: 9.6v 1700mAh(small-type) 9.6v 2400mAh(large-type)


Approx. CHARGING Time on 1000mAh Output Charger:
600mAh = 36mins(min) 42mins(std) 48mins(max)
1100mAh = 1hr 6mins(min) 1hr 19mins(std) 1hr 30mins(max)
1500mAh = 1hr 20mins(min) 1hr 48mins(std) 2hrs 7mins(max)
1700mAh = 1hr 42mins(min) 2hrs(standard) 2hrs 24mins(max)
1900mAh = 1hr 53mins(min) 2hrs 18mins(std) 2hrs 43mins(max)
2000mAh = 2hours(minimum) 2hrs 24mins(std) 2hrs 48mins(max)
2400mAh = 2hrs 23mins(min) 2hrs 54mins(std) 3hrs24mins(max)
3000mAh = 3hours(min) 3hrs 37mins(std) 4hrs 13mins(max)
*Charger should be 1 to 3 volts higher voltage than total battery voltage
Go over to http://digibattery.com for more battery-charging-time calculations
DISCHARGING: Number of batteries in a Pack = Max discharge volts.
(ex. 9.6v = 8cells in a pack = 8.0v is the maximum discharged voltage)

- - - - -

PISTON: Depends on your spring and trigger abuse.
M140 Above = Aluminum Piston (for ratatat players)
. Choice1: ICS Aluminum Piston
. Choice2: Systema Aluminum Piston
*if compatible, get the half-tooth to lessen the weight
M140 Below = Polycarbonate Piston
. Choice1: Guarder Polycarb Piston (blue)
. Choice2: Tokyo Marui Stock Piston (white) <-- polycarbonate too
. Choice3: Systema Polycarb Piston (black) << brittle bad choice
AVOID the RED PISTON-Systema Polycarb (defective) there's a newer version
*haven't tried the TGS(blue), TOP or Prometheus Hard Pistons yet, but it looks promising <-- pls review
*some use polycarbs on m140 above but with trigger care

- - - - -

CYLINDER: (cylinderVolume-to-barrel-ratio) 2 is to 1 (standard)
Marui Stock Cylinders:

1. Closed Cylinder = 27.1cc 450mm(min) 580mm(max) barrel length

2. XM Cylinder = "4/5 hole" = 364mm(min) 460mm(max) barrel length

3. M4 Cylinder = "3/4 hole" aka Type-2 17cc - 229mm(min) 430mm(max) barrel length

4. MP5K Cylinder = "mid hole" 9cc 110mm(min) 170mm(max) barrel length


Systema NB Standard and BoreUp Parts:

1. Type-0 Cylinder (closed) fits M16-A1,VN,A2,G3-A4,SG1,SIG550,AUG

2. Type-1 Cylinder (tip hole) for XM177, M4, AK47, AK47S, SIG551

3. Type-2 Cylinder (XM hole) for MP5-A4,A5,SD5,SD6, MC51,SIG552

4. Type-3 Cylinder (M4 "3/4" hole) for MP5 PDW

5. Type-4 Cylinder (MP5K mid hole) for MP5K
*BoreUp Closed 29.4cc = 500mm(min) 600mm(max) barrel length

- - - - -

KM Cylinder Parts:

*Intercept Cylinder 59 barrel length from 450mm to 590mm (Type 0)
*Intercept Cylinder 45 barrel length from 250mm to 450mm (Type 2)
*Intercept Cylinder 25 barrel length from 100mm to 250mm (Mid-hole)

*To avoid confusion, don't mix brand model names, just model equivalence
*TM M733 by stock is closed cylinder (Type 0) -over ratio

- - - - -

RATIO Guide:
Standard-Efficient Ratio is 1.5 is to 1
2-2.5 : 1 for springs up to M130 --- 2.5-3.0 : 1 for strong springs M140 -> UP
