Daniel Defense, although a relatively young company first started in 2000, has made an indelible mark on the tactical AR market. Combining top-notch quality, cutting-edge design and word-of-mouth endorsements from those in the know, the Daniel Defense M4 series of AR carbines are extremely well respected in tactical circles.
At the heart of this success is a simple but telling tagline with which the company dubs its weapons: Mil-Spec+. If you are familiar with the current semi-automatic market of AR carbines, you undoubtedly have run across the seemingly unending debate over who makes true “Mil-Spec,” who does not, and what the term actually constitutes. The concept of what is “Mil-Spec” carries such weight because the current M16 has served for roughly five decades in one form or another with the U.S. military, which has resulted in a design that has been refined and enhanced through significant real-world experience.
So the question of which semi-auto AR variant most closely fulfills the stringent requirements of “Mil-Spec” is a source of significant contention in some circles. And, obviously, the variant that most closely replicates all these advancements in a semi-auto form is of great interest to the LE officer looking for the best possible patrol/tactical carbine that can be acquired.
