Hey guys, looking to upgrade my CRB into a DMR, I plan on increasing barrel length to 430mm with a Prometheus barrel and increase FPS to as close to 500 as I'm able to get without changing anything in the gearbox, yes I'll be locking to Semi dont worry as otherwise in the UK that thing would legally be becoming a firearm Anyway, what would be the best spring for me to get without changing gearbox and any other small things I can do?

hi guys, I have a guy asking if I'd swap my gun for his after ige listed it, turns ut to be a DMR and I've wanted one a while, claims to be hitting 70-80m accurately with it but I'm unsure as from what I know it takes quite a built up bolt action for that, keeping in mind it's an AEG, Its a £250 specna arms base gun with the upgrades listed in images

Hey guys, I'm not really "new" to airsoft but never really got into missing my guns internals... I'm running krytac Trident MK2 CRB, I am on extending the inner barrel through a suppressor for that extra length but need to know the internals I'd need? e.g. bucking, gears stuff like that, thanks alot :)
