Special Notes:

Keeping with our Warr Dogz style with our large selection of Big Bore Uppers here is our A1 Upper Receiver made from 7075-T6 aluminum. This is not just your standard A1 upper, we enlarged the ejection port along with a relief cut on the upper right side as found on most proper big bore uppers to eject the brass from .450 Bushmaster, .458 Socom, and .50 Wolf. We also do an extra back cut on the upper inner portion of the ejection port opening, for an extra aid in clearing the spent brass. This comes with our single center feed ramp or can get it with no feed ramp. We also removed the roll pin from the forward assist and drilled and tapped it, then added a 1/16" dog point set screw.

The A1 carry handle includes A1 adjustable rear sight, and perfect for building a retro M16A1E1, M16A2 Carbine Model 723, or a Model 733 Commando. The upper has a shell deflector and tear drop forward assist and dust cover. The C7 style carry handle allows mounting a scope from the era for a retro look. Will come with a Milspec Charging Handle.

This Warr Dogz modified LuthAR upper does not have M4 feed ramps in keeping with the military A1 uppers. Use this upper with any Mil-Spec lower receiver. Includes 1 color Cerakote, other Cerakote upgrades. Optional caliber engraving.

Please allow 1-2 weeks, possibly sooner for Cerakote.
