Sometimes reading is fundamental
Spike's Tactical 16" Mid-Length .223/5.56x45 caliber Complete Upper Receiver assembly for AR15/M16 type Rifles. This is a COMPLETE Upper receiver assembly, everything except a rear sight, and includes Spike's Tactical Tungsten filled ST-12 heavy recoil buffer
and Magpul MOE heat shield lined handguard. You will be hard pressed to find a better deal on a quality Upper Receiver than this one.
I haven't found any range reports on the Rguns NiB BCGs but for an extra $75 I'd rather go with spikes
