That’s something I didn’t think about and definitely something to consider, so I appreciate your input. But, I’m a right handed shooter and the charging bolt is on the right side. Not the left, so, finger crossed, my ugly mug will be spared if there’s a failure of some kindYou want what you want, and I get it, but here are some thoughts on side chargers. When an AR goes Kaboom... which is rare, the design, as is, takes the top rail and blowes it up and peals back slightly, the left side swells and directs pressure down into the mag well the right side with the bolt cover cracks at the two thin parts where the ejection port and barrel extension meet, and peals back slightly. Now, mill a slot in the left side, instead of swelling and directing pressure down, it now comes out the left side, if anything is on the left side to now blows out or off. The side charge bolt handle departs in a backward trajectory and the lowest side part peals back quite far, and your face is now on the side where most of the pressure is directed, instead of down and to the right. Now I have yet to see any real bad injuries from an AR coming apart outside of some eye and superficial cuts, but that changes to some serious cuts and parts imbedding once the left side is weakened.
