it takes the same effort to swing an AR at a door knob every time... your gonna hit it as hard as you can every time so that you dont have to do keep doing it.
first thing you learn is that knowing " a little" will get you killed. most of my family members were in the service from WWII, Korea & Vietnam they all like to "teach".
yeah ive been beat with a ball bat, hit with a hammer, slashed with a knife & it wasnt peeling apples... or a family member... what i was taught is why im still alive.
NO: im not in the military(if thats what you mean)... didnt pass the physical. lmao
how that relates in breaking a polymer lower? or saying that they are no good? im curious for the tie in, cause if this is where you tell me that since im not in the military, i dont know anything about building/testing/using guns... dont waste either of our time.
