FX Crown Mk2 GRS stock issue

[cahil_2]

Have any of you GRS stock owners had an issue with the long air fitting not fitting in the opening for the foster fill. The short male foster fits but the knurled longer rubs on the wood and will not latch on the fitting. I don’t know if I should enlarge the stock opening or not.

Get a skinny long one...

Your mileage may very, but I'm using this.

Longer FX friendly female quick-disconnect fitting. Used to fill PCP airguns with recessed fill port like the FX Airgun. One end has 1/8 Female NPT Threads and the other has the Extended Female quick-connect.

Yes, the wood is about 1mm too high to prevent certain foster fitting to lock. Get the long one from link above, you can also shave/sand down the wood about 1mm, I did both.
