Tanaka m700
 

Hi.

My new tanaka m700 shoots so bad. The BB´s goes up an down, no matter how the hopup is adjusted. It looks like the hopup is working, if i look in 2 the barrel and adjust it, it moves. At 25 meters the BB can go from hitting the ground or going 3 meters over target. I have tired a new inderbarrel + a new hopup rubber and last but not least a new mag. The weapon is only about 2 weeks old. Plz HELP ME : i am using Straight O.36g and 0,43g. BB´s

What weight and brand of bb are you using?

Straight O.36g and 0,43g.

The KJW M700 do the same thing. Caused by a change in velocity in every shot.

You must get the velocity to become stable. The bolt is adjustable on the KJ so I am guessing you can adjust it on the tanaka. Adjust it down to 400 fps ( guess) and hopfully it becomes more stable. Right now it is shooting max everytime. The gas in the mag changes every shoot so each max shoot is different.

Try taking the bolt out and stretch the spring. When I first got my m24 bb’s rolled down the barrel. After the spring was stretched it shot nice and consistent.

BUT I still have a problem... My m24 shoots far but the bb's always go way to the left for some reason. Will a tightbore barrel correct this ?

sorry to hog your thread nk666 I just didn't think that my post was worth a new thread.
tks to all the people who help me out.

but the Tanaka m700 is on gas ?? so watt spring are u talking about ? The one that is inside the bolt carn´t stop the bb´s or am i wrong :)

There is a spring inside the bolt that is used to hit the valve. Pop out the bolt and take a look at it.

: :grin: i will try that thx, hope it works

:cry:

what gas are you using? Can you take a pic of your bolt? Wanna see how far your power is set.
