I have the FoxfireTP also. I really like that you don't need an Allen wrench to move the pins. The sight seems pretty solid and the ring does fit nicely in the peep.BUT... If you have to change a pin due to breakage (Like I had to) it is a real pain in the butt! I had3 guys at the range try to replace the pin and nobody was able to. I had to take it to a proshop. For this problem alone I wouldn't buy it again. Granted I'm not the handiest guy around but replacing a pin on this sight is rediculous.
