Spike's Tactical is a US manufacturer which creates high quality parts, uppers, and complete rifles. Every component is manufactured to Mil-spec standards and is backed by the Spikes Tactical lifetime warranty.

Any outstanding AR platform rifle must have a fantastic upper receiver. The Spikes Tactical M4 "Slick Side" Upper Receiver is the mil-spec upper you have been impatiently waiting for! This receiver is precision machined from forged 7075 T6 aluminum. It's engineered to exceed your expectations with the features you need in a flat top upper receiver and nothing you don't! The forward assist has been machined off for that clean smooth appearance and a weight savings of nearly 1.5 ounces! M4 feed ramps were cut into the receiver before anodizing to avoid reliability issues and an ejection port door is already preinstalled for you. Featuring laser engraved T-Markings and the Spike's signature Spider Logo, the M4 Slick Side Upper Receiver is the perfect addition to your next AR build!
