As My first post I would like to tell everyone about tech-sights. They give You the same sight picture as a service rifle(AR,M1,M1A)and are a big improvment over the stock iron sights.I got Mine on GunBroker and I have to say it was the best $50.00 I ever spent. You get front and rear replacement sights.The rear sights screw into the scope mount holes,But the original front sight has to be removed before the new one can go on.I did it Myself and it was easy. I have the TSR200 on My 10/22 and they have improved My shooting. www.tech-sights.com
