My Experience with the Spikes Tactical Billet Upper Receiver Assembly Block: Here’s the Truth
The Spikes Tactical Billet Upper Receiver Assembly Block promises to be the last upper receiver block you’ll ever need. Spike’s Tactical aimed to create a durable and professional-grade tool for cleaning, maintenance, and assembly of AR-15 upper receivers. As an armorer and firearms enthusiast with over a decade of experience, I was eager to see if it lived up to the hype, especially compared to the myriad of other options available.
For years, I’ve cobbled together various methods for working on upper receivers, from improvised jigs to less-than-ideal clamshell designs. I was looking for a solid, stable platform to make tasks like barrel swaps, gas block installations, and general cleaning easier and more precise. The promise of a billet aluminum construction and a dedicated, no-compromise design is what initially drew me to this product.
Upon receiving the Spikes Tactical Billet Upper Receiver Assembly Block, I was immediately struck by its weight and robust feel. The hard coat anodized finish looked incredibly durable, and the machining was clean and precise. Compared to my existing polymer clamshell, it felt like a serious upgrade. Initially, I was impressed and optimistic, envisioning a future of easier and more efficient AR-15 builds and maintenance.
Real-World Testing: Putting Spikes Tactical Billet Upper Receiver Assembly Block to the Test
First Use Experience
I first tested the Spikes Tactical Billet Upper Receiver Assembly Block in my workshop while assembling a new 300 Blackout upper receiver. The ambient temperature was comfortable, but the shop can get dusty from time to time. My initial task was to install a free-float handguard and gas block.
The block seemed to hold the upper receiver securely, but I quickly discovered a major flaw: it did not fit my left-handed Stag Arms upper receiver. This was incredibly frustrating, considering information online suggested it would work. Despite the solid construction, this lack of compatibility significantly hindered my ability to complete the assembly.
Extended Use & Reliability
Given the incompatibility with my primary left-handed builds, extended use was limited. The block felt durable during the brief testing on a standard right-handed upper. The anodized finish seemed resistant to scratches, and the overall construction showed no signs of weakness.
Cleaning the block was straightforward; a simple wipe-down with a cloth removed any oil or debris. However, the lack of compatibility with left-handed uppers makes any further long-term testing irrelevant for my personal use. For right-handed uppers, there were no issues.

Who Should Buy Spikes Tactical Billet Upper Receiver Assembly Block?
The Spikes Tactical Billet Upper Receiver Assembly Block is perfect for AR-15 builders and gunsmiths who primarily work on standard, right-handed upper receivers. It’s also suitable for those who value durability and a professional-grade tool. It’s a great addition for anyone looking for a long-lasting, reliable solution for their AR-15 building needs.
However, anyone building or maintaining left-handed AR-15 uppers should skip this product. Those looking for a more budget-friendly option might also consider a polymer clamshell style, although they might sacrifice durability.
A must-have accessory to use in conjunction with the assembly block is a quality armorer’s wrench. Proper lubrication for the upper receiver components is also recommended.
Conclusion on Spikes Tactical Billet Upper Receiver Assembly Block
The Spikes Tactical Billet Upper Receiver Assembly Block is a well-made and durable tool, but its limited compatibility with left-handed upper receivers is a significant drawback. For right-handed AR builds, it offers a secure and stable platform.
The price, at $84.75, is justifiable for the quality of materials and construction, assuming it fits your specific upper receiver. However, the incompatibility issue makes it a questionable value for a segment of the market.
Personally, I cannot recommend the Spikes Tactical Billet Upper Receiver Assembly Block due to its incompatibility with my left-handed AR builds. It’s a well-intentioned product that ultimately falls short for a significant portion of the AR-15 community. Consider your specific needs and upper receiver compatibility before making a purchase.
