Does the rear GR sights by Mossberg go on the receiver? It looks in pictures like a barrel-mounted affair...
George, I am interested in a receiver peep sight for my SGs, but in every catalog I've looked the Williams are called out as being made of aluminum...are there any peep sights made of steel (Lyman?) that could be finished to match the gun - i.e, parkerized? Would parkerizing destroy the adjustment mechanism (and while on this subject, would you kindly take a look at my post on parking and tolerances?)
Thanks
