Top 10 AR-15 Rifles of 2019

Windham Weaponry CDI AR-15 rifle black left side profile

Anyone in the market for a new AR should start with a Top 10 list and then narrow it down by sorting the wheat from the chaff. Like any good Top 10 AR-15 rifles list, there is plenty of room for debate. There are models that should have been included and those that should have been left on the cutting room floor.

So here are my top picks in no particular order. Your mission, should you be willing to accept it, is to put my list in proper order while feeling free to build your own list. However, if you want to swap out a different rifle for one of these, be sure to provide your reasons why.

  1. I’ve shot the Ruger, Colt, Daniel Defense, Rock River and Stag. Liked them all, especially the DD, but the Stag? What can I say about a company from whom I purchased (4) AR platform rifles (agency purchase) and (3), yes, (3), were defective. That was about (7) years ago, so I’ll give them the benefit of the doubt and hope they’ve squared themselves away, both in quality and dishonest business practices. They were terrible for service, too. We ended up eating (1) of them, because we “waited too long to report the problem”. That was the response after (3) failed attempts to even reach anybody for service. Will never purchase another.
