I am interested in buying Tactical/Sniper rifle. I was originally going to have a rifle built to my Specs but, the cost was toomuch for my income. I am looking for a precision rifle with adj. saddle comb and adj. LOP McMillan stock Leupold mil-dot scope, 1/4-1/2 MOA accuracy,and capable of shooting accurately out to at least 800 meters. I am currently looking at th Tango-51 built by tactical operations. Does anyone have any preferences between th Bravo, Echo, Delta, or Sierra models. It has to be a .308 or .300Win Mag. I am open to hear of any other rifles out on the market for under $4,000.00 Thanks for your input.
