Ctshooter......
Thanks for responding bud. The rifle will be his own rifle. We would not be sharing it and switching the charging handle back and forth. It will be committed left. Holding a heavier, longer rifle can be difficult to keep from dropping down when shooting off-hand which is mostly what we do. You are correct wth charging with support hand if on a bench, sticks, or bags. Hmmmmm.....
