I am looking for recommendations for sights for a ruger 10-22. I'd like to keep the 10-22 as simple (non-tactical) as possible, and want to stay away from placing a scope on it. The sights currently on it are the 'standard' pseudo-flip-up rear sight and the front post. I am interested in a 'peep' style sight, but wanted to ask you all out there what, if anything, you'd recommend. Thanks.
