Need to make room for my R700 short action BDL so I can load to 2.9 in. With a Wyatt's extended box you need to cut out the action a little to fit the box AND also cut the bolt stop. With the AICS longer detachable mags (2.95 internal width) using a M5 bottom metal I know I will need to cut out the feed ramp a little but never heard anyone mention if the bolt stop needed to be modified as well. I don't mind cutting into the stock to fit an M5 bottom metal and making the cut to the feed ramp (if that's all I have to do). The Wyatt's sounds like it's more work on the receiver and might require more that I can do myself with a dremel. Am I right about the M5 conversion with the longer box as far as action work?
