Hi guys..
I've just ordered a .25 bullpup knowing that I'll have to work a lil bit on it as the stock velocity is only 240 meters per second and I'd like it to be 280 meters per sec and I know there is nothing to do on the Hammer and Hammer spring to achieve this kind of tuning.
So... I'll have to work on the transfer port a'd maybe the barrel port to allow more air to pass.
My question is... What's the best way to drill your transfer port? Is there anything I got to know before I start the tuning please???
