Don't worry about impacting your zero on a red dot by swapping it between firearms. This complete upper comes equipped with a Vortex Strikefire II Red/Green dot. Don't worry about tracking down a new magazine either. Included in the package is a 9 round magazine that fits standard AR-15 MIL-SPEC lowers. This upper is built on an 18.5" barrel to offer accuracy without creating a top heavy firearm.
