They not only have sights, they have rugged, useable sights that work well with a peep.
I am sure there was a std sling stud in the box when I got mine. I'll have to dig out that box as I leave all the "paraphernalia" in the box. I prefer the strap anyway. I ran a latigo sling thru it and leave it slung. I use it for shooting. It deserves its own and it's always ready to go. Wouldn't be hard to change to a stud if you wanted to. I don't think it would really devalue the gun if you did it so it could be put back. I'd make it the way I wanted anyway. If it ever gets sold it'll be after I'm gone and I don't think I'll be worrying about the price
Wood on mine is fairly plain as are all that I have seen. Sometimes some nice straight grain. I have never seen a nicely figured piece of wood on one, ever. I'm talking about old #1 type of wood. Has anyone?
Mine is a favorite deer rifle. A good shooter and easy to carry. I highly recommend trying the NECG peep sight. I really believe it made me a better shooter and it works great w/ the RSI. If the rifle is wearing a scope the peep is in my pocket. I have swapped them around and they both hold zero. It carries even nicer w/o a scope. You give up a few minutes of low light, but I think I'm faster w/ the peep. Once you get it dialed in you just slap the bead on target and squeeze. Really a lot of fun. My groups are the same at hundred as w/ the scope w/ 50+ yr old eyes so don't let that deter you. My groups with the flip up sight open up a bit and they are a lot slower than the peep. If you can see the front sight the peep will work.
Have fun with that new RSI.
