The only time it gets tricky is if the vendor (or some subsequent gunsmith) used threadlocking compound on any of the screws. Then things can get interesting...
This is less likely on an air pistol than on a .22, especially on any fasteners that would be removed for normal maintenance like seal replacement.

Re: Max # of pellets through barrel?
I ordered the seal kit from the vendor above and so far after ruining what was left of my "bolt seal" to get it out I found that at least that one isn't part of that kit. Now the pistol is not just underpowered....10M_Stan wrote:FWIW, these guys from the UK sell seals for the FAS 609: http://www.ebay.com/itm/FAS-AP604-amp-A ... 1796162015
They are listed as Bagnall & Kirkwood Ltd with a1tackleshop as their Ebay store. I've always had good luck buying airgun spares from the UK.
This post indicates that Tim at MAC1 can (has) reseal a FAS AP609: http://ttorg.targettalk.net/viewtopic.p ... &view=next
Of course, this is hearsay and may not be accurate. Here is the contact information for MAC1: http://www.mac1airgunshop.com/aboutus.asp
Good luck!

I guess I'm off to the local machine supply house tomorrow!
Re: Max # of pellets through barrel?
Here is link to the manual for a FAS 604: http://www.pistoliers.com/manuel/Manuel_Fas_604.pdf
A diagram in that manual appears to have part numbers which coincide with the o-ring part numbers sold by the Bagnall & Kirkwood Ltd a1tackleshop Ebay store. That diagram shows a breach seal instead of a bolt seal (but then, it's for a 604). For reasons that aren't clear to me, European and even German manufacturers will use inch (AS568 standard) o-rings instead of metric (ISO 3601). Perhaps those two specifications overlap? Either way, there's a limited number of choices available so trial-and-error will eventually prevail. Good luck!

Re: Max # of pellets through barrel?
FAS wont tell me what 604 seal sizes are but I use 2 off each of the British Standard seals below. Being fractional inches they indeed correspond to SAE as well.
BS610 17/64 x 25/64 inch
BS007 5/32 x 9/32
BS115 11/16 x 7/8
Buy 10 of each in NBR70 from a bearing shop on ebay rather than a "set" of seals. Cheap and you know what you are getting.
Plenty of German weaponry in WW1 was inch sized. Like Napoleon never existed.
