m16/ar-15 is direct impingement
>no fag its stoners own design, the piston and bolt are one in the same
ok, does it shit where it eats?
>no fag its an extremely reliable system with the best recoil impulse in the world, vietnam was using shitty ammo without cleaning kits just don't use shit ammo
the u.s. documents that the system is easily fouled and is switching to the short-stroke hk416
>cause the army is retarded and the marines are crayon eaters who they want dead anyway
tons of live footage of civilians and police ar-15s jamming without them hitting anything
>cause they were using shitty ar's and shitty ammo and theyre fudds who can't hit shit
Afghani shitters and chicken nugget scoons managing to hit soldiers using sheer grace of god doctrine with 30 year old ak's .
>they still lose and die to u.s. soldiers
who uses the system correctly then?
>I do you fucking faggot
whats the situation you are going to be using it in?
>shtf and home defense
