which of course also effects your ability to swiftly shoulder the rifle and get precise hits. Disassembly of the stock is necessary, and the use of wax and Accraglas Gel will get rid of all the unnecessary "play" between the parts. Once this is done, and the Accuwedge installed, shouldering and hitting with the CAR is just as fast as it is with the AR(ie, about .20 second faster than it is with the unaltered CAR) An optical sight(on a flat top AR) will also knock off .10-.20 second for such a move-hit) depending upon how practiced you are with irons, and how good your eyes are. The optic is a nice option for NOW, in case of a short term"mission) and for winning combat rifle matches.
