First Impressions of R&D Precision Pw9R Bufferless 9mm Upper Kit Complete
The R&D Precision Pw9R Bufferless 9mm Upper Kit Complete promises a streamlined, recoil-managed shooting experience with the ubiquitous AR-9 platform. This kit immediately stands out with its bufferless design, eliminating the need for a traditional buffer tube and spring, potentially opening the door for more compact builds or unique stock configurations. The promise of reliable 9mm performance in an AR platform, without the cumbersome buffer system, definitely caught my attention.
I was looking to build a compact, easily transportable AR-9 for range use and home defense. The bufferless design offered a solution to the limitations of standard AR buffer tubes when paired with folding stock mechanisms. Unboxing the kit, I was immediately impressed with the solid feel of the upper receiver and the smooth finish of the handguard. The weight felt balanced, and the overall build quality seemed robust; a testament to the R&D Precision brand.
I considered other 9mm upper options from Palmetto State Armory and CMMG. However, the bufferless aspect of the R&D Precision kit, with its integrated recoil system, ultimately swayed my decision. My initial impression was one of excitement and cautious optimism. I was eager to see if the performance matched the promises.
Real-World Testing: Putting R&D Precision Pw9R Bufferless 9mm Upper Kit Complete to the Test
First Use Experience
My initial testing took place at an indoor shooting range, a controlled environment to evaluate basic functionality. I mounted the R&D Precision Pw9R Bufferless 9mm Upper Kit Complete on a standard AR-15 lower receiver using a 9mm magazine adapter. The upper cycled flawlessly with various 9mm ammunition, ranging from 115-grain FMJ to 147-grain JHP rounds.
The bufferless system offered a noticeably different recoil impulse compared to a traditional AR-9. Instead of a sharp “thunk,” the recoil was more of a gentle push, making follow-up shots quicker and more comfortable. I was surprised at how well the system handled different loads without any adjustments.
Extended Use & Reliability
After several range sessions spanning a few months, the R&D Precision Pw9R Bufferless 9mm Upper Kit Complete continues to perform admirably. I’ve put several hundred rounds through it, and it has proven to be remarkably reliable with minimal cleaning. The black anodized finish has held up well, showing only minor wear marks in high-contact areas.
Cleaning is straightforward, requiring only basic AR-15 cleaning tools and solvents. The absence of a buffer tube simplifies the process. It outperforms my previous experience with a traditional blowback AR-9 setup, particularly in terms of recoil management and reliability.
