Why do people build their own AR-15 instead of just going downtown and getting one pre-made off the shelf? If you're careful you might just save a couple of bucks, but that's not the real motivation behind the build. You do it because the gun that you really want isn't somewhere on a shelf, it's swirling around in your mind. Every AR-15 user knows the importance of a good upper receiver; it is a very decisive point on the AR platform rifles. Spike's Tactical offers the Forged Mil-Spec AR 15 Upper Receiver for those who demand first-rate components for their AR-15.
Spikes Tactical M4 Flat Top Upper Is Built To Last
As you begin to amass the parts for your build, you will be hard pressed to find a better forged upper receiver than this Spikes M4 Upper Receiver. Due to the machine time involved, you can get a forged upper receiver for less than half the cost of one that is machined from a billet. Now, a billet receiver will likely be prettier, but strength and durability are just about even with its less costly forged brother. The Spike's Tactical Forged Mil-Spec AR-15 Upper Receiver is machined from a solid forging of 7075-T6 aluminum, then put through a type-III hard coat anodizing process. Spike's has machined M4 feed ramps into this piece to improve its reliability. A Picatinny rail on top allows you to mount optics or sights with no modifications necessary. The forward assist and ejection port door also come pre-installed!
Start Your Build Right with Spikes M4 Upper Receiver
You could use the cost savings from the Spikes Tactical M4 Flat Top Upper to begin your collection. Regardless of how many guns we have, there seems to always be just one more that we would like to have.

Additionally, going this direction you can outfit each Spikes Tactical M4 Flat Top Upper with a different length barrel and sight options. You can transform your long range varmint rifle into a CQB weapon literally in minutes. Like every Spike's Tactical product, this upper is machined with the utmost precision, so it will install easily and function flawlessly.
