Well i would never get a bsa rifle again.The reason is i have owned 2 bsa r10 both mk1 and mk2 and the mk1 went back 4 times to bsa to get repaired.The mk2 went back twice.I have owned aout 5 air arm rifle in the past and WOW they are the dog's banger's.I still have the 410f and use it all the time.i did have the r10 mk2 and the 410f like you and i think i used the r10 twice as the air arm comes first.I don't know if i was unlucky with bsa or they are crap.I just think air arm are the best made rifles out there.
