Mastic dispenser/caulk gun type thing that fits a standard cordless?

[cjard]

i see hat it's possible to buy a tool that looks like a cordless screwdriver and a mastic/caulk/silicone gun combined. I've got a lot of beads of sealant to run out and it's quite thick..
Makes my arms ache somewhat but my labourer really struggles as he's a fair bit weaker and his lines of mastic end up looking like pigeon ****. I figure that if here's a device that attaches to a normal cordless it should produce reasonably consistent beads then all I have to get rough to him is how to hold a cut nozzle at the correct angle (a task in itself)

Short of throwing hundreds at a dedicated gun, anyone know of a cheaper attachment for existing cordless?

Why not just spend £40+ and buy a ryobi caulking gun?

It's worth every penny

I fear that 40 quid ish is the body only price, no battery, no charger which makes it rather hard to use

All my kit is Bosch, and they don't seem to make a caulking gun.. I guess I could see if I can find a knackered charger for mine and use he connector to interface one of my batteries to the ryobi.. Every other gun on fleabay seems to be 150 plus, and for that I think I'd rather leave a fan heater on the tubes of mastic and hope the lad develops bigger arms quickly!
