Hello.

I have the KJW m700p, im wondering about some uppgrades.

I use redgas or propane in gas magazines, the gives about 590-600fps
Our clubs sniper upper fps limit is 700fps, but im goin to Berget 10 this year & i cant go over 648fps because of that.

I also have a Madbull Co2 regulator++
But im hoping it will sufice without it.

I use King Arms .4 BB's in "cream" colour
http://www.pyramydair.com/s/p/King_Arms_6mm_Airsoft_BBs_0_40g_2_000_Rds_Orange/939
Im really happy with these bb's anyone else tried them?

For now i have only upgraded the Hammerspring & Hop-up.
I've ordered a Deep Fire 650mm 6.02 barrel, and a G&G Hop-up bucking.
I also ordered the Tanaka 27rnd. magazine.

These are the uppgrades i'm thinking of:

http://www.redwolfairsoft.com/redwo...ng_Arms_Nozzle_for_M700_A_I_C_S_Version_2.htm

Will these uppgrades up my rifles performance drastically?
Or im ok with the parts i have ordered?
Does anyone here have experience with these parts?

The power bolt won't work with that extended nozzle unless you can get a machinist to get the nozzle out and put the longer one in.

Stick with the stock bolt and just replace the nozzle and the striker spring in the bolt.

As for the barrel/hop-up, you'll want a new bucking and a better barrel that's int here stock. I'd recommend a significantly shorter barrel than the one that comes in it. Most have goo experiences with around 450mm in length. You'll also want to make your own barrel spacers. You also don't need a new hop-up chamber for the use of VSR-10 buckings, but I'm not sure if that Creation Chamber that you listed works or not.

For the magazine, get the G&G Powerpack parts and then tap the magazine and run an HPA rig so you can have consistent, adjustable FPS.

That should be about it, but I'd also experiment with different hop-up spacer designs because the stock one that comes in that rifle isn't very good.

Ok so stick to original bolt.
Striker spring is G&G upgraded already.
650mm 6.02 barrel is already on the way... (i like long barrels...)
Not going for HPA, cant stand external tank & hose.
C02 or gas only...

Powerpack parts i will try i think.
Barrel spacers i will make somehow, using tape for now... lol.
Hop-up spacer... anyone have ideas on how it should/could be?

I'll look for the thread where a guy made an H-Spacer for the rifle.

I'd really re-consider the external air rig if I were you though. It's really the single most important upgrade you can do for a gas rifle. Without it, your long range accuracy will suffer. You can only get green gas/propane/unregulated CO2 to be so consistent.

If I were you, I'd just make something small, similar to a cold shot rig and put it in a pouch on the stock. All you'll be able to see will be a thin rubber hose running from the bottom of the magazine to the stock pouch.

I'd make a full length barrel spacer if I were you. You could make one out of wax or expandable foam. Electric tape could even work, but it would be tedious to make.

EDIT: Found that thread after some digging:

Hope this helps, these rifles are really pretty simple to work on and easy to get shooting well. For the bucking, I'd go for a purple Nineball; they seem to do the best out of the VSR-10 series buckings.

Didn't I make a hop up spacer for you? Did you get to test it out??

Yes you did, I haven't been able to get the funds together or the time to buy a Tanaka long magazine at the moment (my KJW is in an AICS stock). I won't be able to get back into the sport until summertime due to classes and everything. I'm sure it does perform significantly better than the stock one due to the design though.

This is the Co2 adaptor i have, with a paintball "end" & hose.
http://www.redwolfairsoft.com/redwo..._XM_Charger_XC03_Portable_12g_CO2_Adaptor.htm

I tried it out today, a friend of mine has a HPA rig on his Tanaka M700, so i borrowed a magazine from him.
I adjusted to 200-220psi & chronoed in at 630fps with .20 bb's

When i get the 27rnd' Tanaka magazine it should be more stabile, fps drop wise.
went down to 610-620fps after a really fast reload, but with the bigger magazine i would dare to guess it wont drop down that much in pressure between shots.

I giddy in antissipation for the new barrel & mag to get here so i can upgrade the rifle.
At it's current state i have a effective range of about 75-80meters
(had a lucky shot today at 98ish meters :)

Madhellsing: could you make me a hop-up spacer? & maybe some lightweight barrelspacers?

The problem with that is your aren't putting a liquid gas in your magazine. That means that the FPS will gradually drop off each and every shot unless you re-fill after every shot. This is why a hose being attached works so well.

The new barrel should help a bit, but getting your consistency down to about +-3 FPS is what will really helpout long range accuracy.

PM him; his prices are very reasonable and he is very quick with everything. The spacer I got is very high quality and yes, he does make barrel spacers also.

EDIT: I also definitely wouldn't go that high on the PSI or you could tear up the magazine and it won't fit in the magwell. Especially if it's a long magazine. Ideally, you shouldn't have to use more than about 110-130 PSI to get a high FPS. Also with an air rig, the lower the PSI, the better consistency and quicker time to get the PSI back up after a shot (this can be important if you need to do a quick follow-up shot).

Im going to have a hose into the bottom of my magazine, & the co2 thingy in a stock pouch.

hmmm.. 100-130psi?

isn't that wery low?
Several people in my club use co2 rigs & they are all in the 200psi range, even with the long mag.

Sorry, didn't catch that. I've heard of people trying to fill their magazine with the fill tip on the end of the one you linked, which wouldn't work very well at all. Yeah, you should be good with that.

Actually no, that's on the high end. My stock KJW M700 ran at 120 FPS and was shooting a bit over 550 FPS. Really, 110 is ideal once you have a nice barrel and good airseal. 200 PSI should yield a very illegal FPS.

Check this thread; he was hitting 790 FPS with a 0.20g @ 130 PSI.

I managed to change out the barrel this weekend, but the G&G hop bucking did not fit, seemed like it was too "short".

I also figured out that my Hammer spring was not tightened all the way, so i did that too.
Gonna check fps & accuracy thursday, im at work right now (truckdriver) so not really feasible to try it here... :)

I made baffels in my silecer also... it worked realy good, gas cloud coming out was heaps smaller.

Which bucking was it? The only G&G one that I know of is the red bucking and contact patch that comes with the circular airseal piece for the bolt. This is for stock Tanaka rifles. The KJW uses the VSR buckings/barrels.

That my friend would be the source of my troubles... :cheers:
Atleast the bolt rubber fit...

i think i might be able to use ordinary hop bucking...

My truck btw :) Scania R series' 15.6 litre V8 with 500 whp

Most people buy it just for that little airseal piece though, so don't worry. I would save the little contact patch though; some have used them as a R-Hop patch in an AEG.

That things a monster; looks a little different than the ones over here. I would never be able to drive something that large. The largest thing I've ever driven was a decent sized box van and that was tough lol.

Oh, it's not that bad, it's only 17.5 meters long :)
