Timber Creek .300 AAC Blackout 8.5″ Pencil Barrel Review

The Timber Creek .300 AAC Blackout 8.5″ Pencil Barrel Made a Bold First Impression

The Timber Creek .300 AAC Blackout 8.5″ Pencil Barrel immediately caught my eye with its promise of lightweight performance and compatibility with the versatile .300 Blackout cartridge. As someone who appreciates modularity and building custom AR platforms, I was eager to explore the possibilities this barrel offered, especially given its pistol-length gas system, ideal for compact builds. Could this barrel be the foundation for my next close-quarters, suppressed AR pistol build?

I’ve always been drawn to the .300 Blackout for its subsonic capabilities and effectiveness at shorter ranges. My main challenge was finding a quality barrel that wouldn’t add unnecessary weight to my build, allowing for better maneuverability. The “pencil” profile immediately signaled a focus on minimizing weight, a feature that trumped other barrels with heavier profiles designed for sustained fire.

Unboxing the Timber Creek .300 AAC Blackout 8.5″ Pencil Barrel, I was immediately impressed with the clean, even black nitride finish. The threading appeared precise, and the included thread protector was a nice touch, indicating attention to detail. The barrel felt surprisingly light in hand, confirming my expectations about its profile.

Compared to similar offerings from Ballistic Advantage and Faxon Firearms, the Timber Creek barrel stood out due to its aggressive pricing without compromising on the black nitride finish. While Ballistic Advantage offered barrels with similar profiles, their cost was significantly higher. Faxon Firearms, known for their lightweight barrels, lacked the attractive price point of the Timber Creek option.

My initial impression was one of cautious optimism. The price was fantastic, but I was keen to see if the barrel’s performance would live up to its promise. Would it group well with both supersonic and subsonic ammunition?

2. Real-World Testing: Putting **Timber Creek .300 AAC Blackout 8.5″ Pencil Barrel** to the Test

   First Use Experience

My first outing with the Timber Creek .300 AAC Blackout 8.5″ Pencil Barrel was at my local outdoor shooting range. I mounted it on a dedicated AR pistol lower receiver with a quality pistol brace and a red dot optic, eager to see what it could do. I ran a mix of supersonic 110-grain V-MAX rounds and subsonic 220-grain rounds through it, both suppressed and unsuppressed.

The performance was surprisingly consistent, even in the slightly breezy conditions. Using a suppressor with subsonic rounds created a remarkably quiet setup. This barrel performed admirably for the cost.

I noticed that the gas system ran reliably with both supersonic and subsonic rounds, although the unsuppressed subsonic rounds resulted in a few failures to lock back on an empty magazine. Adjusting the gas block (not included with the barrel) would likely remedy this. The lightweight profile made the AR pistol incredibly maneuverable.

Extended Use & Reliability

After several months and hundreds of rounds, the Timber Creek .300 AAC Blackout 8.5″ Pencil Barrel has proven to be a reliable performer. There are no signs of significant wear or tear, even with regular cleaning and maintenance. The black nitride finish has held up well against scratches and minor abrasions.

Cleaning is straightforward, requiring only standard AR-15 cleaning procedures. The bore cleans up easily, and the nitride finish seems to resist carbon buildup. Regular lubrication of the bolt carrier group is essential, as with any AR platform.

Compared to my previous experiences with budget-friendly barrels, the Timber Creek barrel has exceeded my expectations. It’s not a match-grade barrel, but it delivers consistent performance and reliability at a fraction of the cost. It has quickly become a favorite for its lightweight, compact profile.
