I was looking for a reliable and accurate upper receiver for a dedicated hog hunting build. The 350 Legend cartridge has proven to be effective on medium-sized game at moderate ranges, making it an ideal choice for the thick brush and dense forests where I typically hunt.

Before settling on this Aero Precision upper, I considered a similar offering from Bear Creek Arsenal and a complete rifle from Ruger chambered in 350 Legend. I chose the Aero Precision upper due to Aero Precision’s reputation for quality and the M4E1’s enhanced features, particularly the seamless handguard integration. The Aero Precision upper offered a balance between premium features and cost.
My initial impression was excitement mixed with anticipation. The build quality appeared excellent, and the enhanced features of the M4E1 upper inspired confidence. I was eager to see how it would perform at the range and, ultimately, in the field.
