First, welcome.
Second, I was like you with the stainless heavies. Enough was enough and I have plenty.
I built a post ban M-4orgery on a MEGA lower/upper combo with a Bushy Patrolmans Carbine M-4 chromelined barrel 16", 1X9 and haven't looked back. The RRA Varmint will do you well, but you need to experience a leightweight to truly appreciate a "Handy" rifle that is capable of acceptable accuracy. My total cost to build mine was $680 with all new parts. I have 7 AR's and countless other target/varmint/bench guns. An entry stock would give you a short stock, but I didn't like it. Look around, go and feel some rifles. I'm confident you will find what you want reasonably priced. BTW, these guys are the best, they will steer you in the right direction, be patient.
