I want to build an AR-15, in .223 wylde, 6.5 grendle, .50 beowulf. Two lowers, three uppers. I have about $3500 to build. Uses: .223: varmint and target practice. 6.5 grendle: light game and varmint at distance. .50 beowulf: any thing under 200 yrds.
I have no experiance with an AR-platform.
1. Parts needed?
2. upper and lowers? billet, forged, coated, polished, painted. Internal coating or polished billet for better operation?
4. muzzle break???
or should i just by a rtf ar?
