Which adapter do I need

[Jmeddings]

Hi I have an ARP9 and bought a Acetech Lighter tracer for it, but the thread on the tracer is too small to fit the gun.

Does anyone know what size adaptor I need for it to fit ?

You know it has an adapter that screws out?



Also you might find you need a 14mm ccw thread extender because of the ARP9 rail being so close it will probably block the tracer unit screwing on to it.

Have you taken the plastic loudener off the barrel?

Heres what I mean about the rail getting in the way. Video isn't in english but you can see visually the problem.

I have just unscrewed the plastic loudener

I didn’t realise I had an adapter the screws out thanks. Mine does not screw out easily can’t do it by hand might have to put it in a vice or something

I just watched the video thanks for the link .

the tracer I bought fits inside the rails no problem it’s diameter is fine. 

I looked on a few other threads and everyone said the acetech lighter does fit the ARP9 fine without an extender.

Guess now I just got to figure out how to get the adapater to screw out of the tracer
