Falcon fn o ring sizes.

Recommended Posts

Posted (edited)

On my recent quest to be tight, I've come across a chart for o ring sizes for the above gun. Instead of ordering kits, you might find them cheaper at specialist sites or buying what you need. Ive personally a fn 19 in .177 and are now going to look where to order certain rings from cheapest 

In the chart, under reference, when your searching use bs infront 

So example transfer port - bs802. 

Also use a shore hardness which is higher as it will last longer (most are 70,80 or 90 - best) 

Hope this might help somebody else if they Google or use this sites search facility.
