Swap out Plastic body??
Basically I am just looking to see some people opinions on if I should do it or not based on my situation. Option no.1 I can buy a full metal M4A1 and eventually change the hand guard as the one I want does not have a rail. Option no.2 I can buy a Nylon body gun with a metal rail system and comes with a PEQ box and just switch out the plastic stuff that should be metal to metal. In your opinion as I am a beginner what would you advise me to do?
