I have 2 thropy pin sights... I love them!!! you have to try things out to see if its for you...see if you can buy one on the chep from someone who didn' t like them to save money..... the pins do block your vision on long didtances but this was addressed with the 2003 model which uses smaller pins .029 - .019.... this makes aiming easier for long distances..very easy to set up and use......company stands by their products...... good service deptment.....
