I was recently thinking of trying out a gas BASR and stumbled upon a pretty good deal on a Tanaka M700 AICS. It has a tapped mag, and most of an external rig. All I would need is a reg and the tank itself (I believe).

Now, after doing some research over the past 2 days (and reading every post refering to an M700 on these forums) I have discovered that my first task is to replace the hop with a KA unit, a new housing, a nice bucking, and a better inner barrel.

Now for the hop chamber, I've found the KA conversion kit on evike for like $80. I also found on evike the housing (I think) made of CNC by Creation, for $65.

However, I also see that G&G has several parts for this rifle as well, including a Hopup set for roughly $26 ,

My question is which to use? I know that this topic has been brushed upon a thousand times, but I cannot find any post that outright says which is the best, or who uses what, or if I even need to.

G&G also has a smattering of other parts for this rifle found throughout the web, and I am curious if I were to need any of these as well.

Please help! Or delete if you don't feel I've done enough research on my own heh.

I would suggest you to this thread here: http://www.airsoftforum.com/board/Ultimate-Parts-Guide-ge-t194133.html
It has loads of good information, and don't worry if you scroll down it has been put through Google translate.

As for the various chambers, The KA chamber is made so that VSR cut barrels can be put into the gun, and I believe that the other two chambers are just made for durability and do not come with an adapter for VSR barrels, but I am not absolutely sure. The reason for the G&G and creation hop up set, is that the plastic hop up housing (Part #91) is very easily broken if the screw securing the outer barrel is over tightened, which before those parts you had to buy the whole G&G heavy outer barrel kit to get part #91.

The translation is a little hard to comprehend at times in that guide so here is my understanding of these parts.

Many of the G&G parts are just for durability since they are made of stronger material than the stock pieces, but in some instances they have been reported to increase consistency, and sometimes increase velocity. But as you will see in the parts guide they can caused increased wear on other stock pieces. The striker spring is a must have if you are going to HPA. It's stronger than the stock spring and allows the valve to open completely at higher pressures. Without it an HPA setup can't really be fully utilized unless you are running it at lower velocities. The G&G gas route spring replaces the spring that pushes the valve on the magazine up against the gun when you load in the mag, this gives you a better seal and a little bit more consistency. The G&G rubber kit comes with three rubber pieces, but if you are switching to VSR style hop up only one of them can be used, the one that fits into the bolt. The rubber is a higher quality material and gives you a better seal and a bit more consistency. The G&G plunger replaces the stock plunger arm and impact plate, reducing the overall mechanism by one part, and has been said in some instances to create more consistent FPS. The valve knocker just gives you better durability as does the steel cocking piece and bolt handle. According to the writer of this guide, the G&G power-bolt can give you better consistency IF you have ALL other G&G parts, otherwise it causes large amounts of wear and can ruin the gun.

So you can decide whether or not you need them, personally I would get the G&G power pack which has many of these parts and the G&G gas route spring. The rest of the parts are said to only be needed when they break or get too worn. That barrel conversion and a new barrel would be a great investment of course.

Hope this helps.

Thank you for your answers. But am I to understand correctly that the g&g housing would be an alternative to the creation housing? If I were to get the KA conversion kit, and the g&g instead of the creation, that would save me like $40?

But I do appreciate your help, I am significantly more confortable buying this rifle than before!

Yes it would save you $40, but, the creation chamber is stronger and its threads are much thicker. A lot of people worried about this but people say once they get it and put it in that it's fine. You may just want to keep your plastic housing until that breaks. I have heard of some people making a little plastic spacer to stop over tightening.
