Peep Site for T/C Firestorm??
 

Is it possible to mount a rear Peep site of some sort on a T/C Firestorm to shoot more accurately? I find the large rear fiber optic site difficult to use past 40 yards.

As far as attaching another site, all I see on the barrel is one screw in the top of the Firestorm barrel about 1/2 inch in and then the rear fiber optic site about half way up the barrel.
