So I’ve really liked the Magpul PRS gen 3 stock on my 6.5CM RPR, but it has one major draw back. It’s LOP is shortest possible measurement is 15”. My AICS chassis 700 is set up for me right around 14”. I’ve contacted Magpul twice in the matter and get the same “we don’t currently offer any shorter butt pads for the Gen 3 at this time”. Cool story, but not what I was looking for. I love the feel and love the adjustable butt pad, but I was just about ready to give up and prowl for a PRS gen 2 or the LMT Precision Stock. I really didnt want to give up the adjustable butt pad. So after me and a buddy both in the same predicament. He found a buried thread on M4carbine about a guy chopping his carbine tube adapter in his Gen 3. Wheels started turning on how to cut it and I ended up here. The cut landed me just a hair over the 14” mark ??. You could take it lower but you would have to modify the carbine tube stock adjustment lug channel from the back end from what I saw. The stock still locks up very tight on the tube with no real compromise of it potentially sliding after being altered (my buddy and I both pulled really tight on the stock with just the rear screw tight and couldn’t get it to budge. So the QD slog mount screw only made it tighter!) When the Gen 3s first became available I saw a guy on the RPR thread asking if there was any alternative to the long LOp. I’m 6’ tall so I figured we weren’t the only people bummed out about this so I’d like to share some pics of the Mod.
