The rifle is mass. ok.The one I shot had a great trigger,and did not jam.It is hevy compaired to a ar15 and kicks much less.My bud got one for his daughter and she loved it.It is hard to take apart but you can watch a vid on u-tube to see how its done.As you know ar mags fit but some may not be drop free.Also they do not have much for accories.If you mount a scope or optic you will want a low rise base style.The rifle is fun to shoot and has a huge fireball depending on ammo.I think you will like it,good luck.
