I recently had to cannibalize my beloved m16 knock off as it seemed like a bcm barrel on felt like a waste. Instantly I'm missing my m16 knock off and wanna restore it as cheaply as possible.
Where can I find the absolute cheapest 20", rifle length ar barrel? I don't can if its used of not. If I comes with an f mark front sight, then that's even better since I had to cut off my last one.
