First Thoughts on the KeyMod 15-4/Short Ext Tan
The KeyMod 15-4/Short Ext Tan drop-in handguard promises a modern upgrade to the classic AR-15 carbine. Offered by an unnamed manufacturer, its extended length aims to provide more real estate for accessories and a sleek, continuous top rail. This tan variant offers a distinct aesthetic change from the standard black, promising a unique look.
I was looking for a cost-effective way to modernize my AR-15 without completely replacing the gas system or upper receiver. I wanted more KeyMod rail space for mounting lights and foregrips, while maintaining a clean, streamlined appearance. The KeyMod 15-4/Short Ext Tan seemed to fit the bill perfectly.
Upon unboxing, I was immediately struck by the lightweight aluminum construction. The tan powder coat appeared evenly applied and durable. The fit and finish seemed decent for the price point.
I considered other drop-in handguards like those from Magpul and Midwest Industries. However, I chose the KeyMod 15-4/Short Ext Tan due to its extended length, which offered more rail space and a more seamless appearance. The included KeyMod to Picatinny rail sections were a bonus.
Initially, I was cautiously optimistic. The lightweight design and promise of easy installation were appealing. However, I was slightly concerned about potential fitment issues and the durability of the tan powder coat finish.
Real-World Testing: Putting KeyMod 15-4/Short Ext Tan to the Test
First Use Experience
I installed the KeyMod 15-4/Short Ext Tan on my AR-15 and headed to the range. The installation was straightforward, requiring only the removal of the existing carbine handguard. The new handguard fit snugly, with minimal wobble.
The range conditions were dry and sunny. The KeyMod 15-4/Short Ext Tan performed well, providing a solid mounting platform for my accessories. The extended length allowed me to position my foregrip further forward for improved control.
Using the provided KeyMod to Picatinny rail sections was simple. I attached a weapon light and a vertical grip to the handguard. After tightening all screws, they held firmly in place.
Extended Use & Reliability
After several range trips and approximately 500 rounds fired, the KeyMod 15-4/Short Ext Tan is holding up well. There are a few minor scuffs in the powder coat finish where accessories were tightened, but overall, it looks good. The handguard remains firmly in place, showing no signs of loosening or shifting.
The tan finish has proven to be relatively durable, resisting scratches and fading. Cleaning is simple; a quick wipe-down with a CLP-soaked rag removes most carbon buildup. The handguard has exceeded my initial expectations in terms of durability and reliability.
Previously, I used a standard M4-style handguard. The KeyMod 15-4/Short Ext Tan offers significantly more mounting options and a much more comfortable grip. The extended length also provides better heat dissipation.
