I have a like new FP-AG with an 0.050 aperture listed for sale on a popular auction sight. It's not cheap, but it's not easy to find and the auction fees eat a lot.
Gorilla Glue?
A Beeman scope stop can be used with your R7 11 mm dovetail, or with a 13mm early type dovetail too...
I switched my R7 from the Daisy Match Diopter to the Beeman 4x32 scope because the peep was sliding. One holer w/ scope @ 10m.I got this R7 in March 2021 from Flying Dragon, cocks very smooth, no noise in cocking or shooting.But the chrono from FD has JSB 8.44 gr at 628 fps and I now have it with same pellet at 581 fps for approx 1 fpe less.Passes tissue test so breech seal is OK - So now asking - is it the piston seal.It came from FD with Mike's OE tune. I have not opened it, in case I send it in for warranty.
