R&D Precision PW9 9mm Gen 1 Bufferless Upper Kit Review

First Impressions of R&D Precision PW9 9mm Gen 1 Bufferless Upper Kit

The R&D Precision PW9 9mm Gen 1 Bufferless Upper Kit promises a compact, reliable, and innovative solution for AR-9 enthusiasts. From R&D Precision, this kit aims to eliminate the need for a traditional buffer tube, opening up a world of possibilities for ultra-short builds and unique AR-9 configurations. I was immediately drawn to the PW9‘s bufferless design, a feature that promised improved maneuverability and a cleaner aesthetic.

I’ve always been fascinated by pushing the boundaries of firearm design and customization. The allure of a more compact and streamlined AR-9 pistol platform was irresistible. The PW9’s promise of reliable function without a buffer tube seemed like the perfect solution for my CQB training needs.

Unboxing the kit revealed a collection of well-machined components. The billet upper receiver looked robust, and the forward charging assembly felt smooth in operation. The finish on the barrel and handguard was consistent, suggesting attention to detail during manufacturing.

Compared to other AR-9 upper receivers I’ve used, the PW9 immediately stood out due to its bufferless design. Traditional AR-9 uppers require a buffer tube assembly, adding length and limiting compactness. The PW9 offered a potential for a significantly shorter overall length. My initial impression was overwhelmingly positive – this kit seemed poised to deliver on its promise of innovation and performance.

Real-World Testing: Putting R&D Precision PW9 9mm Gen 1 Bufferless Upper Kit to the Test

First Use Experience

I tested the R&D Precision PW9 9mm Gen 1 Bufferless Upper Kit at my local shooting range, focusing on close-quarters drills and rapid target acquisition. The range offered a variety of shooting scenarios, from static paper targets to dynamic steel challenges. The performance was impressive, with the PW9 cycling smoothly and reliably with various 9mm loads.

Conditions were mostly dry, with a slight breeze; no extreme weather was encountered. The PW9 performed flawlessly despite this. The absence of a buffer tube made maneuvering in tight spaces noticeably easier, allowing for faster transitions between targets.

The forward charging handle took a bit of getting used to, as I’m accustomed to the standard AR-15 charging system. After a few magazines, it became second nature. No malfunctions or hiccups were experienced during the initial testing session.

Extended Use & Reliability

After several months of regular use, the R&D Precision PW9 9mm Gen 1 Bufferless Upper Kit has proven to be remarkably durable. I estimate I’ve put well over 1000 rounds through it. Only one minor malfunction occurred.

The finish has held up well, with only minor signs of wear on the charging handle. Cleaning and maintenance are straightforward, with easy access to the bolt carrier group and barrel. The recoil brake assembly is simple to disassemble and clean.

Compared to my previous AR-9 experiences, the PW9 has far exceeded my expectations regarding compactness and maneuverability. Its reliability has been solid. The responsive customer support from R&D Precision further solidified my confidence in this product.
