Let’s Dive into Tiger Rock 5.56mm AR-15 Complete Upper Receiver
The AR-15 platform has become a mainstay in the American shooting landscape, and building or upgrading your rifle is a popular pastime. The Tiger Rock 5.56mm AR-15 Complete Upper Receiver promises a Mil-Spec build, ready to drop onto your lower and get you shooting. This upper receiver aims to provide a cost-effective solution for both first-time builders and seasoned AR enthusiasts looking for a reliable option.
I was looking to complete a budget-friendly AR build for a training rifle. I wanted something accurate and dependable without breaking the bank. I had a spare lower receiver and decided an affordable complete upper like the Tiger Rock would be the perfect solution.
Upon unboxing, the initial impression was fairly standard. The finish appeared consistent, and the weight felt appropriate for a 16-inch AR upper. The Tiger Rock upper receiver arrived pre-assembled, which was a welcome time-saver.
I considered a few other uppers in a similar price range, including offerings from Palmetto State Armory and Anderson Manufacturing. I opted for the Tiger Rock because it boasted a free-float handguard, a feature often found on more expensive models. This seemed to offer better value and potentially improved accuracy.
My first impression was cautiously optimistic. It wasn’t flashy, but it appeared functional. The real test would be its performance at the range and long-term durability.
Real-World Testing: Putting Tiger Rock 5.56mm AR-15 Complete Upper Receiver to the Test
First Use Experience
I tested the Tiger Rock 5.56mm AR-15 Complete Upper Receiver at my local outdoor shooting range. The weather was typical for spring: a little windy with intermittent showers. I mounted the upper on my existing lower receiver and paired it with a variety of magazines and ammunition types.
The upper performed adequately in the slightly adverse conditions. There were no immediate failures to feed or extract, even with cheaper bulk ammunition. The included muzzle brake seemed effective at reducing recoil.
I did notice the handguard felt a bit slick, especially when wet. There weren’t any significant issues, but I wished I had worn gloves for a better grip.
Extended Use & Reliability
After several range trips and roughly 500 rounds through the Tiger Rock 5.56mm AR-15 Complete Upper Receiver, its reliability has been acceptable. I experienced a few failures to eject with one particular brand of steel-cased ammunition, but it ran reliably with brass-cased rounds.
The finish has held up well, with only minor wear marks on the ejection port cover. The free-float handguard remains secure, and there are no signs of loosening. Cleaning the upper is straightforward, with easy access to the bolt carrier group and barrel.
Compared to my higher-end ARs, the Tiger Rock doesn’t offer the same level of refinement. It is a good value for the price, offering functional reliability for training and recreational shooting.
