Well, I provided you with a list of pretty much all of your options in Post 111. At the end of the day, what folks recommend you buy is going to largely depend on how much you are willing to spend. Bear in mind that you will also need to feed your new .223/5.56mm rifle, with a case of 1000 rounds of 55gr ammo costing approximately $670 (plus tax) on sale these days....
Personally, I would place the minimum "sweet spot" at $3K, which allows you to purchase (in priority):
1. The Lockhart "Silver" Raven (~$2500 plus tax), plus 500 rounds of ammo.
2. Sterling Arms International R18 Mk2 with standard Trigger Tech Trigger ($2700), plus 300 rds of ammo.
2. Crusader Templar with upgraded Trigger Tech Trigger ($2200) plus a full 1000-round case of ammo, OR a lightly used Tavor X95 (~$2500) plus 500 rounds of ammo. This choice is all about whether you can work with a bullpup or not....
YMMV, but any of the above ought to serve you well at the $3K price-point. Good Luck with your quest!
