RISE Armament AR-15, 22 ARC, 18 inch Complete Upper Receiver Review

First Impressions of RISE Armament AR-15, 22 ARC, 18 inch Complete Upper Receiver

The RISE Armament AR-15, 22 ARC, 18 inch Complete Upper Receiver promises a potent blend of accuracy and modern design in the increasingly popular 22 ARC chambering. RISE Armament has built a reputation for quality AR components, and this complete upper receiver looks to continue that trend. The 18-inch stainless steel barrel, free-floating handguard, and upgraded bolt carrier group signal performance right out of the box, making it a compelling option for AR enthusiasts seeking enhanced precision and longer effective range in a smaller caliber.

I was looking for a dedicated varmint and target AR upper that could offer flat trajectories and minimal recoil, something that I could use for longer range sessions without beating myself up. The 22 ARC round seemed to fit the bill perfectly. My aging eyes also aren’t what they used to be, so a smaller caliber helps me track my shots better.

The upper arrived well-packaged, and my first impression was definitely positive. The fit and finish were excellent, with a smooth Cerakote finish and no visible blemishes. The handguard felt solid and comfortable in hand, and the RISE Armament ambidextrous charging handle was a welcome upgrade over a standard milspec handle.

I had been considering a similar upper from a competing brand known for their lightweight builds, but the RISE Armament seemed to offer a more robust construction and a more comprehensive feature set at a similar price point. I was also looking at a custom build with a Proof Research barrel, but the cost was significantly higher. I chose the RISE Armament AR-15, 22 ARC, 18 inch Complete Upper Receiver for its balance of price, features, and claimed accuracy.

Overall, my initial impression was one of excitement and anticipation. It seemed like a well-made upper receiver, and I was eager to get it to the range and see how it performed.

Real-World Testing: Putting RISE Armament AR-15, 22 ARC, 18 inch Complete Upper Receiver to the Test

First Use Experience

My first range trip with the RISE Armament AR-15, 22 ARC, 18 inch Complete Upper Receiver was at my local outdoor range, focusing on accuracy at 100 and 200 yards.

The conditions were fairly mild, with a slight breeze and clear skies. The upper functioned flawlessly from the start, with no feeding or extraction issues. The recoil was noticeably lighter than my 5.56 AR, making it easier to stay on target and spot my shots.

I did find that I needed to adjust my gas block slightly for optimal performance with my lower and ammunition. This is typical, and easily corrected. The rifle length gas system paired with an adjustable gas block delivers a very smooth recoil impulse.
