The only way i can think of doing this on the cheap is cutting the stock back say 40mm and glue in 2 ferruls then have say 4 x 10mm spacers held in place by 2 long screws through a rubber recoil pad.
The reason why im looking at doing this is if we have either young or short people using our (in fabrication) club F Gun.
We had this problem last week but the Mcmillan stock on the loan rifle was adjustable for length.
Any thoughts
