Was looking at the dicso receiver and it appears tall enough to cut into to fit a mrod mag. The bolt probe would have to be lengthened of course but that looks like an easy fix.
Speaking of bolt, I find the stock dico bolt to be rather small and uncomfortable to cock. Does anyone have an aftermarket bolt?
There are several makers of aftermarket bolts. Take a look around this link, I think you'll find something. I am hesitant to recommend one maker over another, they are all quality products.
