The Best 6.5 Grendel Uppers in 2023

The 6.5 Grendel has become one of the more popular choices for long-range shooters in the last several years. When compared to the 5.56mm, the larger round of the 6.5 adds long-range oomph where the 5.56 NATO can fail to impress.

In this piece, we’re going to cover some of the best 6.5 Grendel upper receivers on the market, with a dive into Palmetto State Armory in particular, which has gone deep into Grendel with their line of uppers. We’ll review the benefits of a few different versions of their offerings as well as other top options.

And because nobody is satisfied with a list of products, we also take a look at the origins of the 6.5 Grendel, the history of the round, its benefits and shortcomings, and some suggestions for how to choose the best 6.5 uppers for your needs. This article is part of our ongoing Guide to Everything AR.
