Another madbull blue thread!

Southern Dandy

Hows the going,

Guna put a madbull blue hop up into my kwa, it fires at 322fps well that is what was wrote on my box (don't have a chrono). Will the fps jump by much with the madbull blue? I don't want it firing hot.

In theory no, that is assuming that your existing hop-up rubber and air-nozzle are making a perfect air seal
So replacing the rubber for a different make should have no effect on the fps

Now the above statement is all theory, but in practice things are different
The MadBull blue is a great rubber and gives excellent results so I would not be surprised if you saw a small increase in FPS

Just because it says 322fps on the box when it was tested does not mean that it is still shooting at 322 today
If it has fired many thousands of shots since last chrono then due to a bit of wear on the piston O-ring it way have lost a few fps along the way
So best bet is to get the fps checked after fitting the MadBull rubber for peace of mind sake and if you wish you could also get it checked before just to see if it makes a notable difference

Id say a thousand rounds if even i havnt skirmished it yet like. I don't know anyone with a chrono and the closest shop is around an hour and a half away so bit of a trek just to get it chrono'd.

Well i put the madbull blue in and to be honest I was shocked the kwa hop was way more consistent not to mention it was a pain in the bloody hole to fit, this is defo down to kwa's two piece chamber being as tight as a ducks arse id imagine but yeah the kwa stock was better (and no i did not install it incorrectly).

I fitted one then in the brothers g&p sentry aswell and it worked like very noticeably improved accuracy and range weird but what can you do.

That's the thing with the Madbull Blue Hop-Up rubber, it's a 60 Degree rubber. I bought a Madbull Hop-Up (Complete Kit) a month ago, placed the rubber on my inner barrel, tried to place the Hop-Up chamber... didn't work so well. I tried to use a bit of grease, oil, whatever you want to call it..., still, as you mentioned "tight as a ducks arse" it was. Your better off using a 50 Degree rubber.
