We offer 5.56/.223 and 300 Blackout AR 15 Rifle Uppers that come fully assembled. You can choose from M-Lok, KeyMod and fixed front-sight assembly styles with stainless steel or black barrels and fixed front sights to give you varying options depending on your preferred shooting desires. The only other tools you will need to make your AR 15 Rifle Upper a fully-functional rifle is an 80% lower, AR-15 lower parts kit, butt stock, buffer tube and an 80% lower jig to mill out the fire control group of the lower receiver.
