Hi guys,

 

I am thinking of changing the spring in my Dboys AK 74 for a weaker one, as playing with 390 fps is proving to be difficult when searching for sites that allow this kind of power.

Any ideas for what type of spring I should change it in order for me to go to most games? including CQB too..maybe??

I was thinking about a M105 spring. Something that will keep it at around 330-350 fps.

The inner barrel in this AK 74 (RK-05) is 502 mm. So it might be a bit over, perhaps M100 would be a better choice? Again, average fps of 340 would be perfect.

 

I'm thinking about this spring: https://www.amazon.co.uk/ELEMENT-M105-SPRING-AIRSOFT-AEG/dp/B00AE3W7QI/ref=sr_1_1?ie=UTF8&qid=1479851045&sr=8-1&keywords=m105+spring

 

or this one

Thoughts?

 

btw.

 

According to the website, the stock spring is M125. lol.

If that gun has a m125 in there you should be over 400 as longer barrels tend to increase or creep the fps up a bit

 

Yes you could have a m125 in there but reckon you might be losing a bit with a slight leak

 

I'd go with a m100 max tbh

Or

A m95 if you get it sealing better

 

Deffo do not get a m105 or m110

 

The cylinder in there should without doubt a full unported one as you need every bit of volume for that long barrel as it's kinda pushing it on a normal gearbox cylinder
