Hi there everyone. I'm new here and excited about building my first AR in 308. My main use of this rifle will be for deer hunting/target shooting so I am considering barrel of 18 inches or so to keep it light and compact without degrading performance of course. My biggest concern of course is accuracy, I want sub MOA groups out of the build keeping great accuracy at further yardage as well. So I am all ears for tips and suggestions. Below are the parts I am leaning towards so far... JD Machine Billet Receiver set - I read nothing but superb reviews on this. MEGA ARMS MA-TEN Receiver set - Same thing with JD set, looking good. Magpul PRS stock Magpul PMAG 20LR - Which I believe is compatible with both JD and MEGA... I hope. Deciding on JD or MEGA receiver sets is killing me lol. That's what I got in mind so far... As far as barrels,triggers,bolts and such, I am still hunting. Pet peeves of mine are that I want a quad picatinny rail Handguard (free floated) A muzzle break, and a fluted heavy barrel if very accurate. I don't want to skimp on anything. Well that's a wrap so far, looking forward to everyone's advice! Thanks, Tom.
