Gunsmithing What gas rings for a GAP-10?

[bdcmh]

I have a GAP-10 and it is not cycling reliably the bolt will not stay in place if I lift the carrier. So I suspect that the gas rings are worn. So, what gas rings do the GAP-10 rifles use? My rifle is a POF pattern rifle.

So, I tried the DPMS 308 rings and they seem to be too thick. I can only get 2 on.

I have called GAP several times and left messages. No response.

I would prefer the continuous ring that came with it but where to get it?

Thanks

It's a McFarland gas ring for Armalite AR10 carriers. This is what's on mine:

bdcmh,

Most everyone from GAP left for the GAP Grind in Florida on the 19th. They just returned on Tuesday the 24th and it's taking some time to get caught up I'm sure.

Regards.
