Which one is the lightest ASA available?

[mpsd]

I'm building a new Mag to be the lightest possible gun and I currently have a DW on/off adaptor and rail but I'd like to have something smaller and lighter than this. On/off is a plus but not mandatory. So, which one is the lightest ASA available in the market?

Thanks,

Mendel.

The Empire Nano without the on/off.

i think the XSV asa but it doesnt have an on/off its just a duckbill type of asa.
heres a link to one on ebay

There are multiple Empire products with the name "Nano"; there's a "bolt on" ASA and also a rail ASA. I've got both and I agree they might be the lightest... I can get weights if you really want.

if you want a light on/off, the bob long gear drive with the special screws is pretty light considering that it doesn't need long screws to attach or a rail.

the eclipse ones are super light but they require an adapter to use on a non eclipse gun.. and im not sure that even exists

Thanks for the input guys. I'm gonna use it with an AGD CF frame so I'll need some longer screws. I'm thinking about either the XSV one (need a black one, though) or the Machete from Guerrilla Air.
