Just curious as I'm having trouble finding a replacement stock for my 1991 10GA BPS. Seems the main difference is the elimination of the spacer plate and pin in favor of a collar on the stock that fits into the receiver. Is it possible to grind this collar flush and drill a pin hole and use it with the pre 98 frame? OR... is it possible to remove the old spacer plate and fit the new stock into the recess in the old receiver?
Well my friend...wish I could offer a good answer, but that type of work is above my pay grade. Hang tight...some of our members will be around shortly to offer their expertise.
