I've got a 590A1 SPX. I just removed the LPA rear sight from the rail and replaced it with a Burris Fastfire II in a Burris picatinny protector mount. The optic is not much bigger than the LPA it replaced. So far I'm liking it a lot. I was worried that the fibre optic front would be distracting in the field of view of the red dot, but the red dot sits just high enough that all I see is the tips of the wings protecting the front sight.
Your going to put a Red Dot on a Shotgun?????????? Blasphemous I say!!!!!!!!
I had actually been thinking of cutting off the top portion of my ghost ring on the shotgun......I actually liked the blade sights that my 870 had better.
It is actually TSE that has the LPA sights, not Wolverine.
