First Impressions of POF USA Revolution DI 18.5 in Barrel .308 Winchester Upper Reciever Assembly
The POF USA Revolution DI 18.5 in Barrel .308 Winchester Upper Reciever Assembly promises .308 power in a significantly smaller and lighter package, blurring the lines between AR-15 and AR-10 platforms. POF USA has built a reputation for innovative AR variants, and this upper receiver assembly attempts to deliver big-bore performance without the typical AR-10 bulk. Is it just marketing hype, or does this revolutionary design hold water?
I’ve always sought a .308 AR for its increased range and stopping power, but the standard AR-10 platform always felt cumbersome, especially during long patrols. The promise of a lighter, more maneuverable .308 AR led me down the path to the POF USA Revolution DI 18.5 in Barrel .308 Winchester Upper Reciever Assembly. My initial hope was that this platform would deliver the knockdown power of a .308 in a package closer to my trusty AR-15.
The upper receiver arrived well-packaged, and my first impression was positive, it felt solid and well-made. Picking it up, I immediately noticed how much lighter it felt than a typical AR-10 upper, a welcome surprise. The fit and finish were excellent, the Renegade rail felt comfortable in hand, and the nitride-treated barrel looked ready for action.
I considered a complete Daniel Defense DD5 V4 rifle and a custom build using a Aero Precision M5 receiver set before settling on the POF USA Revolution DI 18.5 in Barrel .308 Winchester Upper Reciever Assembly. The Daniel Defense was tempting for its reputation, but I wanted to keep my existing lower receiver. The custom build offered more flexibility, but I preferred the guaranteed compatibility and innovative design of the POF USA.
I was definitely excited upon unboxing, this thing felt like it could potentially change the way I thought about .308 ARs. It certainly wasn’t disappointment; however, I was slightly apprehensive, I wondered if the compact design would compromise reliability or accuracy.
Real-World Testing: Putting POF USA Revolution DI 18.5 in Barrel .308 Winchester Upper Reciever Assembly to the Test
First Use Experience
I initially tested the POF USA Revolution DI 18.5 in Barrel .308 Winchester Upper Reciever Assembly at my local range, which is a mix of indoor and outdoor lanes, allowing me to test it at varying distances. I wanted to get a feel for its accuracy and recoil impulse under controlled conditions. I was using a standard AR-15 lower receiver with a quality aftermarket trigger, as POF recommends pairing it with a good trigger.
The upper performed admirably, even in slightly windy conditions, recoil was more significant than a 5.56 but certainly manageable. I was initially concerned about overgassing due to the shorter gas system, but the 9-position Dictator gas block allowed me to fine-tune the gas flow for smooth cycling with various ammunition types. The ergonomics felt good, and the M-LOK rail provided ample space for mounting accessories.
After about 100 rounds, I experienced one failure to extract, likely due to a combination of a slightly dirty chamber and a weaker ammunition load. This prompted me to immediately clean the chamber and adjust the gas block, after these quick adjustments the rifle ran flawlessly with a variety of .308 loads.
Extended Use & Reliability
After several months of use, including multiple range trips and a weekend hunting trip, the POF USA Revolution DI 18.5 in Barrel .308 Winchester Upper Reciever Assembly has proven to be remarkably reliable. The finish has held up well, with only minor scratches on the M-LOK rail from attaching and detaching accessories. Cleaning is straightforward; the nitride barrel wipes down easily, and the roller cam pin appears to reduce wear on the upper receiver.
I’ve put several hundred rounds through it at this point with only one hiccup during the initial range trip, I have experienced no further failures.
Compared to my previous experiences with AR-10 platforms, the POF USA Revolution DI 18.5 in Barrel .308 Winchester Upper Reciever Assembly is far superior in terms of weight and maneuverability. It’s closer in feel to an AR-15, making it much more comfortable for carrying over long distances. While the accuracy isn’t quite match-grade, it’s more than adequate for hunting and tactical applications, certainly outperforming my expectations.
