Is there anybody out there that knows for sure when one can purchase .25 cal breech seals for the fx smooth twist barrels besides AOA? THREE dollars is a bit much for three cent seal. The size is 1.27mm x 6.35mm. 70 or 90 will both work. I've called over 30 places that sell o-rings in the US and have yet to find anybody that carry that size or anything even close. Thank you.
