Blackbeard01 Posted February 4, 2019 Share Posted February 4, 2019 So I have a b&t sportline mp5 that I'm looking to upgrade. I understand there were better choices but i dont exactly have the funds to go back. My question is will any v2 gear box fit in it? I know they are used in m4s but are these directly compatible or are there suitable differences? Link to comment Share on other sites More sharing options...

Drop in ones almost always need work just to get it to fit. MP5's are one of the hardest guns to take apart as well. Best get a professional to look at it.

Yeah, I've played a game with it already and loved it. I just really lacked in range and I've put a much stronger motor in it as the original was really sluggish. Also rhe battery space is ridiculously tight so need to run a mini lipo really. No, its b&t 14 hours ago, Samurai said: Why? What can't it do now? My main concern is I've put a bigger motor in whichis crazy powerful, halfed the trigger response and then some but I'm paranoid its going to strip the gears. 12 hours ago, Asomodai said: Unless it is a plastic gearbox, its always preferable to keep the original gearbox and upgrade that.

I work as a mechanical engineer so I'm confidant I can learn to do it but the flipside to that is ive got no experience with gear boxes in airsoft guns and dont have a clue where to start.

They handle the Heckler Koch licencing for things like your MP5 airsoft gun which is manufactured by ASG (who probably actually just rebadge someone else's hardware in this instance).

Branded as ASG, licenced from H&K through B&T. Made by a chinese factory based on the Classic Army design (rather than the ICS design). Link to comment Share on other sites More sharing options...

Umarex have the licence for airguns/airsoft, B&T have trading rights for firearms and accessories. Both deal with various manufacturers. Link to comment Share on other sites More sharing options...

It can strip the piston if not shimmed for good AOE (angle of engagement) and will burn the contacts if you don't have FET in there. If you also use it on high ROF then plastic piston head and cylinder heads are much safer than metal ones to keep the gearbox from cracking.
