I have a brand new PSA upper chambered in 224 Valkyrie for sale.
It is complete with bolt carrier group and charging handle, still zip tied in from the factory. It is a 20" stainless barrel, with a 1-6.5" twist to stabilize the heaviest bullets.
This upper fits any standard AR-15 lower.
Also comes with seven boxes of Federal Fusion 90 grain ammo. (Picture shows five boxes, but I have seven)
The 224 Valkyrie stays supersonic out past 1300 yards, it is a fantastic long range groundhog and coyote round.
Everything is brand new.
Price is $425, firm, picked up in Greenville PA area. I will ship for an additional $20. No trades, sorry.
