Hey guys just wanted to throw my build list out there and get some input on what you thought. 1) Upper is a flat top DPMS 223 DPMS AR-15 Lo-Pro Flat-Top Upper Assembly 5.56x45mm NATO 1 9 Twist 16 2) lower is a new frontier LW-15 Complete Polymer Lower [LW-15 Complete (Standard)] - $119.00 : New Frontier Armory - Firearm Sales, Transfers, Ammunition, Gear and More! 3) a vented free float handguard. AR-15 Vented Free Float Tube Mid-Length 4) DPMS pistol grip with palm shelf 5) Magpul PRS stock. Should be able to get all of this for under $900. Does anyone forsee any problems with this plan?!?!
