Opinions wanted. Are these upgrades worth it?

Hedonism Bot · December 10th, 2006, 04:29

Let me just start by saying that I have read the very handy sticky as well as alot of the supplemental stuff around.

Anyway my question is regrding upgrades to my MP5K. It's an essentially brand new Tokyo Mauri.

I'm about to order the following:

Guarder SP90 spring
Guarder ball bearin bushings
Guarder Ported Polycarbonate piston head
Guarder stainless steel cylinder head

Now a few things to keep in mind before you decide if it's worth it:

I play maybe 4 or 5 times a year, exclusivly indoors.
This is my primary weapon (full auto GBB as backup).
My field's limit is 350fps.
I would prefer to keep the stock 600mah 8.4 volt battery but am willing to file down the cocking tube to wedge a 9.6 Volt 1100mah battery if it would make a huge difference.

My goal is a gun that shoots just over 300fps (long range accuracy irrelevant) So do you think I should leave it stock? I have a guy with experiance for the install. I often play with people using upgraded guns and full gear (i wear a t shirt) I don't know how those guys can possibly feel BBs through all that stuff but that's niether here nor there.

I have NO idea what fps the gun shoots at because the only chrono around is at my local field and is built into a wooden box which makes it impossible to get the forerip right up next to sensor. I'm forced to fire from 8 - 12 inches away and the result is usually around 180 - 200 fps. I'm told a stock K fires at about 250.

Any input would be much appreciated. Thanks.

i think that setup should put you around 350 or slightly under. my buddy got his SIG552 upgraded, and he originally wanted an SP90 spring, but went to an SP110 when Bartek told him the SP90 would put around 340fps. you don't really need the piston or cylinder heads, the stock mechbox should handle the spring, new spring guide (a MUST), bushings and shims no problem. see if you can find a custom minibat, there are tons of 8.4V 1400mah's out there, you might have to look around for the 9.6V variety.

the spring, spring guide, bushings and shims should run you around $60-70. and trust me, you want the spring guide, the stock one is plastic poopoo for stronger springs.

8-12 inches away won't make a huge difference to your fps i think. it's good that you want a higher voltage battery since stiffer springs will bring your ROF down.

anyways, i'm only telling what i know, and that isn't that much. if you give Bartek or anyone at the ASC Armoury a call, they can help you a lot more than i can.

cheers

Um, SP90 won't put his gun around 350 on that config. He's got a ported cylinder with a stock inner barrel 1/3 the length of the tightbore was used in ILLusion's test.

Get an Intellect 8.4v 1400mah mini, you don't need a 9.6v.

Greylocks · December 10th, 2006, 11:23

Avoid the bearing bushings.
If the gun is only for CQB, really, I would leave it totally stock.

ILLusion · December 10th, 2006, 16:04

"Ball Bearing Bushings" is the name that Guarder uses for their Steel bushings... even though there's no ball bearings in it.

Regardless, ball bearing bushings (the moving ones with ball bearings in it) would be fine with that setup.

Hedonism Bot · December 10th, 2006, 18:41

I failed to mention that this is the non-PDW model, no stock of any kind. Therefor how could i possibly fit an Intellect 8.4v 1400mah mini into it? Is there a known way of wedging one in there? Not much space to play with. I briefly toyed with the idea of ordering a hollow PDW stock and laying out a custom battery inside of it.

Thank you for the advice on the spring guide, I will certainly add that should i go ahead with the upgrade.

Greylocks, you're not the first person to advise leaving it stock. But like i said, part of me just wants the gun to sting a bit more than it does in it's present state. Do you suggest it because you think there's a high risk of doing more harm than good? Or because even if succesful the differences between stock and these upgrades would be so slight as to not be worth the risk?

thanks

The Saint · December 10th, 2006, 18:47

Forgot MP5K uses stick batteries. Yes, you can get Intellect 1400mah in stick form.

Mantelope · December 10th, 2006, 18:47

They make 1500mAh batteries the same size as the classic 600mAh ones. Check out www.cheapbatterypacks.com, they'll have stock again on the 14th, and they have given me nothing but stellar service.

It hasn't been mentioned yet, but I'd recommend a motor replacement. Since you're stuck with 2/3A cells, you'll get a noticeable increase in ROF with an Eagle Force 1300 or a new SystemA Magnum.

Hedonism Bot · December 10th, 2006, 18:53

I'm drawing the line at barrels and motors. I figure if I start changing the motor and barrel I may as well just buy a whole new gun.

Thanks though.

and thanks for that battery info! I had no idea I had other options that would fit in the K.

ILLusion · December 10th, 2006, 19:04

The Systema Turbo will give a better ROF boost than the SystemA Magnum.

But these are unnecessary upgrades if you're just looking for more velocity.

Greylocks · December 10th, 2006, 20:46

I'm suggesting you leave it stock because you really dont need more than a normal gun for CQB. There is no point in making it 'sting' more. You will only wind up tossing cash into a gun for no real advantage. The ranges dont warrant the upgrades.

Instead, you may want to look into increasing the ROF a bit. Even then, I'd still leave it 100% stock. That way, it's impossible for you to get banned from any CQB game due to a hot gun.

If it's not broken, dont fix it. If it breaks, keep the upgrades simple.

Quoted for being, bang on, and 100% true.

ColtFarmer · December 10th, 2006, 21:59

leave it stock. cut the charging handle down. get some 9.6v batts.

it's a really really really easy mod, and it improves the ROF muchly.

Jimski · January 4th, 2007, 15:36

Hello,

I have noticed that the upgraded vs stock version makes a difference in some situations where ammo speed is important:
I actually got shot sometimes because my BBs were so slow that the enemy ones would get me before mine left the barrel.( during a PDW vs PDW skirmish), which is very frustrating.

vatek · January 4th, 2007, 15:46

TBH, if your K is only shooting 250, then it's probably worth your while to bring it up to normal TM levels, ie, 280-290. Especially if it's your primary.

I don't even think you would need to do much (if anything) to the internals if you brought it up to 280-290ish. Just a spring change, SP85 maybe. I don't think you would see more wear on the internals either.

350FPS is unnecessary for an indoor field.
