Description

If you’re in the market for a flashy way to convert your AR-15 from either a .223 or a 5.56mm NATO caliber to a .300 AAC blackout one, then you need this upper assembly.  Just pull the takedown and pivot pins on your lower, pull your old one off, drop this one onto your lower assembly and push the takedown and pivot pins back into place.  Simple.  All you’ll need after that is to add backup sights or an optic of your choice.

This upper assembly comes with a 16″ parkerized barrel with a pistol-length gas system.  You also get a 13.5″ M-Lok free floating handguard for all your attachment needs, such as grips or tac lights.

One more thing:  this item is on clearance, so once it’s gone, it’s gone.  Better hurry!
