Peep Sight
 

Well i used a tang peep sight and the notche sight. Tang sight 1 for 2, notche sight 0 for 8. not sure if luck or what. pretty easy to use to. shoots great at the range too. Great for in a hurry, look through the sight put pin on and shoot- dont center it or nothing just put pin on where you want to shoot. Just wanted to say my 2 cents.
