Spikes Tactical AR15 Billet Upper Receiver Gen 2

The Spike’s Tactical billet upper-Gen II receiver is not just another different cosmetic alternative to forged upper receivers but it’s actually designed with functional upgrades that aren’t available on other billet upper receivers! 

Spikes machine this bad boy out of 7075 billet Aluminum and finish it in a durable Type III Hardcoat Anodized finish. Of course, they cut the M4 feed ramps before the Anodizing process to avoid reliability issues down the road. We also flared the side walls of the receiver to eliminate accidental bolt release problems and they also machined the upper receiver in a way that lets you use the popular Magpul BAD lever or other aftermarket bolt catch levers which most other billet upper receivers don’t let you do. Because of our beefier design, it allows for less flex than forged upper receivers. 

They also play nice here at Spike’s Tactical and because of that, we machined our billet upper receiver to accept most aftermarket rail systems as well as pre-install the forward assist and the ejection port door. Just like how Spikes billet lower receiver utilizes set screws to retain everything in place, the forward assist is held in place with a set screw for easy disassembly if you ever need to in the life of this upper receiver. 

Spkes billet upper receiver matches their billet lower perfectly, but it also works great with standard forged lowers so it’s fully up to you on which receiver you want to use.

    Tip Of The Hat To Spikes

    Posted by Melvin on 8th Dec 2016

    I received this upper in the mail today (12/8/2016) as Bauer was the only one on the net to have it for a reasonable price and not the $270 MSRP, plus came with the free shipping. I have to say I always felt spikes was a little overpriced until they came out with the Jack Lower, which is still pricey but a nice piece and this upper. The craftsmanship on this upper is TOP NOTCH. Smooth finish, nice design, and great touch to use a allen screw instead of a roll pin for the forward assist. That being said the forward assist and the gas port cover are the only downfalls of this upper as they are both standard pieces. I give this a solid 5 stars. If spikes would have put a forward assist and port cover this upper deserves would have been a 6 out of 5 stars.
