m249 gearbox dimensions

[SHaKaL]

Hey all;

Anyone have the outside dimensions (in details) of a m249 gearbox? and if possible the hopup chamber? It's for a project of mine.

Thanks

Thanks KGBB

Je dessine (pour fabrication) un PKM.



C'est la ou je suis rendu; c'est encore grossier comme modele (mais a l'échele) mais j'ai commencé y'as 3 heures...

Si t'es capable de me donner un croquis avec le plus de dimensions possible; ca serait bien mais je pense pouvoir me débrouiller avec ca.

Je vais me trouver une photo d'un gearbox et la ''scaler'' dans inventor pour avoir les autres dimensions. Au pire vais essayer de m'acheter un shell de gearbox de CA m249.

I don't speak french, but I do believe you are thinking of building a PKM?

Love to hear more if you are!

My M249's gearbox has the exact same dimensions as a version 2 AEG gearbox, and it uses an AUG hopup chamber.
Although the CA249 mechbox doesn't perform any better than a V2 mechbox, It's perfect for what your doing lol

I choose the m249 gearbox because of the switch. And it ability to mount higher than other gearbox. As long as the trigger reach the switch in anyway; there no problems there.

I will be using 16 gauge laser cut sheet metal for the lower. the whole body should cost me less than 30$ in sheet metal. The only thing i'm not sure for now is if the lower will be bended or welded.

The only problem i haven't figure yet is how to make the stamped metal cover... The rest is not that hard to make.

Anyway i am still in the design phase

Nice

CA va bien quand t'est capable de mettre la main sur un vrai pkm désactivé et de le convertir... moins de fabrication mettont!

Anyone know if real parts for a pkm like the feed tray and top cover are prohibited items to import ( from the US?). Those are the parts that are the hardest to replicate and if cant can save by ordering them instead of making them; it would be great.
