Response to FWB 124 specs
I haven't had mine apart for awhile, so I hope someone else chimes in too. What I have in my notes; 28mm piston diameter. 310 grams piston weight. Transfer port is 3mm X 10mm long. Stock spring .118"
I don't remember carefully measuring stoke, but I have seen it listed as 77mm. Seems short to me. A bit mad at myself for not having a good measure in my notes, but gun well buttoned up with Macarri kit inside and loctite, so I don't want to take stock off.
