1st post....
Either you are trolling or this will be your 1st AR.
There really are much better options than the overprived RJ gun.
Before you plunk down that much green, read through this site. It WILL take you days.
My 1st was an RRA offering configured how I wanted it. Still shoot that gun more than any other.
Building one really is easy but may be intimidating for a rookie. My advice is to get a factory made one to
learn how to use (shoot, clean, disassemble, build on, etc...).
You will learn from this site who makes high quality, medium quality and low quality stuff.
I generally am the go to guy in my friends circle that is the "gun guy", and have done lots of builds for my friends.
Everything from Stag/Bushy to Noveske's - and I am by no means a gunsmith.
You can get ALOT of gun for 2,200 bucks - especially if you build one..
