The Checkmate 5.56 lightweight barreled upper assembly for your AR-15 is our best value rifle upper built with quality duty-grade components at an affordable price. This sleek 5.56 rifle upper also shoots .223 ammo, and with it's 1 in 9 inch barrel twist, it will shoot the inexpensive bulk-packaged 55 grain .223 ammunition more accurately.
A complete AR-15 built with this upper will have a total unloaded weight of around six pounds. This will make an excellent choice for offhand plinking, as a hiking companion, or for users who desire a lighter and easier to maneuver AR-15 over a mil-spec upper assembly that is also more accurate.
Bolt carrier group and charging handle are not included with this assembly!
