First Impressions of Tiger Rock 16in Length Barrel AR 9mm Complete Upper Receiver
The Tiger Rock 16in Length Barrel AR 9mm Complete Upper Receiver promises to be a versatile option for AR platform enthusiasts looking to build a 9mm pistol caliber carbine (PCC). The allure of a 9mm AR is undeniable: reduced recoil, cheaper ammunition (depending on the market!), and the ability to share magazines with some popular pistols. This complete upper receiver, offered by Tiger Rock, aims to provide an affordable and readily assembled solution.
I’ve been increasingly interested in PCCs for home defense and recreational shooting due to their manageable recoil and accuracy. I needed a reliable upper receiver to complete my AR-9 build. The Tiger Rock upper caught my eye with its 16-inch barrel, offering a good balance between maneuverability and ballistic performance, especially at an attractive price point.
Upon unboxing, the Tiger Rock 16in Length Barrel AR 9mm Complete Upper Receiver felt surprisingly lightweight. The initial visual inspection revealed a standard black finish. My first thought was whether the coating would stand up to regular range use.
Compared to a similar upper from another manufacturer I had previously considered, this one stood out because it claimed to be a complete package, ready to drop onto my lower receiver, saving assembly time and potential headaches. I was choosing between this and a similar product from Palmetto State Armory, as well as one from Bear Creek Arsenal. I selected Tiger Rock due to positive reviews.
Honestly, I was cautiously optimistic. The low price made me slightly wary, but the promise of a complete, ready-to-go upper was enticing.
Real-World Testing: Putting Tiger Rock 16in Length Barrel AR 9mm Complete Upper Receiver to the Test
First Use Experience
I tested the Tiger Rock 16in Length Barrel AR 9mm Complete Upper Receiver at my local shooting range. The weather was clear and sunny, ideal conditions for sighting in a new upper. I installed the upper receiver onto a dedicated AR-9 lower with a Glock magazine adapter.
The first few magazines were… underwhelming. I experienced several failures to feed. I tried different 9mm ammunition, including both 115-grain and 124-grain FMJ rounds.
I needed a few adjustments to work out some issues with my mags.
Extended Use & Reliability
After about 500 rounds, the Tiger Rock 16in Length Barrel AR 9mm Complete Upper Receiver became more reliable. There were still occasional hiccups, especially with some cheaper brands of ammunition. I’m sure a polished feed ramp would help.
After cleaning the Tiger Rock 16in Length Barrel AR 9mm Complete Upper Receiver, I noticed some wear marks on the bolt carrier, which raised concerns about long-term durability. Cleaning was straightforward, though the tight tolerances around the bolt required extra attention. Compared to my previous 5.56 AR upper, the 9mm version seemed to require slightly more frequent cleaning.
After a few hundred rounds, I was impressed. I would have liked it to run flawlessly out of the box. It didn’t quite outperform my expectations, but I wasn’t disappointed.
