Here’s a point often missed by many. More women can better use an adjustable butt stock on an AR-15, because more often, they require a shorter length of pull. Women are more cheated out of effective self-defense by so-called assault weapons bans. Semi-automatic defense rifles with pistol grips, BTW, have a shorter length of pull than hunting rifles (shorter reach to the hand guard).
The straight-line stock, the low reciprocating mass/lack of gas piston assembly of the direct gas impingement design, of course the caliber itself, and as you mention, the adjustable LOP, make the AR about the BEST home defense tool for women.
People who advise women (who are not regular shooters) to use a shotgun, at least using it with a load that might actually stop an attacker, are either very stupid or evil.
