Real-World Testing: Putting American Tactical Imports AR-15 Complete Upper, 450 Bushmaster to the Test
First Use Experience
I first tested the American Tactical Imports AR-15 Complete Upper, 450 Bushmaster at my local shooting range. The range offers a 100-yard lane, which was perfect for getting a feel for the upper’s accuracy and handling. I tested with Hornady Custom .450 Bushmaster ammunition.
Conditions were slightly overcast, but visibility was good. The upper functioned flawlessly right out of the box. I experienced no failures to feed or eject in the first 50 rounds.
The recoil was significant, as expected from a .450 Bushmaster, but manageable. The included A2-style flash hider helped mitigate some of the muzzle rise. I found that I needed to adjust my shooting stance slightly to compensate for the increased recoil compared to my standard 5.56 AR-15.
Extended Use & Reliability
After several months of use, the American Tactical Imports AR-15 Complete Upper, 450 Bushmaster has proven to be quite reliable. I’ve put several hundred rounds through it without any major issues. The upper continues to function smoothly.
I have noticed some minor wear on the finish around the ejection port, but this is to be expected with normal use. The nitride bolt carrier group has held up well. Cleaning is relatively straightforward, requiring only standard AR-15 cleaning procedures.
I took the upper on a deer hunting trip last fall. It performed admirably, delivering a clean and ethical kill on a whitetail at approximately 80 yards. The effectiveness of the .450 Bushmaster cartridge on large game is undeniable.
Compared to my previous experiences with other AR-15 uppers, this one has exceeded my expectations in terms of value and performance. It provides a cost-effective way to enter the world of big-bore AR-15s. It has been a fun and effective addition to my arsenal.
