The great thing about "Iron Sights" is they are nearly impossible to break, and they do not need batteries, and for a well made plinking gun like the Sig 522 the iTac Sight Set can put a great set of sights on your rifle. The iTac Sight Set for the Sig 522 comes with an adjustable rear peep sight, hooded front sight, and mounting hardware. The adjustable peep sight adjusts both for elevation and windage.
