I got lucky and found a stainless Ruger Hawkeye in 375 Ruger. The gun has a 20-inch barrel and express sights......almost the perfect rifle in my books......however it shoots about a foot low at 50-yards, and the rear sight is not adjustable for elevation. I dont want to scope this rifle and I like receiver sights. The only receiver sights I can find that will fit this gun are the NECG aperture sights. They look to me to be to 'blocky'. Are there any other sights out there that will fit this gun?? I dont have easy access to a gunsmith so even drilling and tapping would take some time. Any suggestions?? Thanks in advance.
