I have a set of Extreme Sniper sight' s on my hunting bow,they are a very good sight,the pins show up real good,and they are verywell made.The pins run on 2 seperate tracks,you have 2 on the front track,and 2 on the back.They will gap real close together.My bow shoots in the 290' s,and I don' t have any problem with pin gap.In my opinion,they are verygood hunting sights.
