Looking for an easy way to make your AR-15 shoot the popular .300 AAC Blackout round instead of its standard 5.56mm round? Get this upper assembly! Chambered in .300BLK, this bad boy makes it easy to swap back and forth from 5.56mm to .300BLK in only a few seconds. Pull the takedown and pivot pins and simply swap your old upper assembly with this one. That's really it!
This complete upper assembly comes to you prebuilt with a 16" parkerized barrel coupled with a 13.5" M-Lok handguard. All you have to do is add either the backup sights or optic of your choice. Hell, your current 5.56mm mags will even work with the .300BLK rounds.
