thanks for that, really appreciate it. I've just ordered the fixed hop unit from airsoft enginuity, wasnt sure which degree maple to go for...any suggestions. I'll hunt for a trigger sear set now, I've managed to download a manual for it online, any recommendations on cleaning, I'm aware that GBBR need more love and attention, my tippman hpa m4 would probably run on dirt, that thing is an indestructible beast lol. also, what gas would you recommend I use, the guy I bought it from had some 3.0 red, i normally use 2.0 green. Tha is again for your friendly advice, most appreciated. Max 😀😀😀 I'm a vector converter now lol
