bilesteve: I'll have to get my SPR out of storage and take a good look at it. We've been on a mini-vacation and just got back so everything is still not handily available. When we leave, things like that are "put away".
Since it is difficult for me to use the open sights due to the kerateconus and have to rely on a scope, I didn't pay real close attention to the set up. When I have questions about Remmy stuff, I do this way. Call 1-800-243-9700, press prompt #4, then in the next menu prompt #3. I believe that puts you into the repair dept. I think the fella's name that I talk to is Greg Thomas. He has been very helpful. He or one of his associates would be able to give you better advice than I. Or, maybe the gunsmith you talked to would have some input on how to adjust it?? I'm sorry that I can't give you a more definitive answer. If you get an answer about the front sight, please post it. Now I'm curious.
I also had looked at the guns you mentioned prior to the SPR. To me the SPR is just a little bit unique and have gotten to really like the spiral twist on the barrel. I also like the way the wood on the forearm is cut somewhat flat on the bottom. For me, it rests very nicely in the hand.
A pull of 4.5 lb really isn't too bad. I'll have to take mine and have it checked to satisfy my curiosity.
Have a great day and happy shooting !
