That's a very expensive rifle.. and should be great for close and fast.. Try the Brownells catalog for mounts..but I'm betting a semi-custom at least mount will be required.. I would advise not altering the rifle much due to it's value..
Thanks for reply.
i love this little rifle ,yes in deed it is a fast handling accurate little darling, but my problem is that i am an old man with old eyes and can't focus on the rear sight as i deed before

this rifle has a great hunting value for me.
i enjoy it now and i leave the market value to my son or grandson to deal with

there are some side mounts on the market, but they are UGLY

.
it is why i decided to look after forward LER mounts . i hope i'll not need to alter too much this rifle maybe just two thiny threaded holes on the barrel!.
all the best
