Ive got one with the factory black front site and a skinner rear peep site, with the screw in insert removed it makes a great ghost ring sight and is far superior in every way to the stock rear sight. I've also removed the safety connector that re sets it to safe every time the rifle is broken open and with my 350 cgc load over 16.5 grains of unique for 1330 fps it shoots extremely well for a 700.00 double and is a whole pile of fun to boot.
