Our 224 Valkyrie upper feature a 18″ Match 1:6.8 twist barrel to get you down range. Starting with an Aero Precision upper each receiver is hand lapped for the best fitment. The Shore Tactical 15″ MLok hand guard has lots of mounting options and is rock solid. Top with or favorite 1776 brake and includes MPI nitride bolt barrier group (BCG) and enhanced Shore Tactical big foot charging handle.
These shoot the best with 75g and 88g rounds.
I build each of these upper myself with attention to detail!
