Summer AR-15 Rifle Series Part 1: Daniel Defense & Sig Sauer

The AR-15 rifle has become one of the most popular firearms in America. It is versatile, customizable, and can be used for hunting, target shooting, and home defense. The AR-15 is a semi-automatic modern sporting rifle that is designed for civilian use, but it is also used by law enforcement and military personnel.

The most common caliber for the AR-15 rifle is .556 or .223, which is are small, high-velocity rounds that are known for accuracy and low recoil. While .223 Remington and .556 NATO ammo look similar, they are not interchangeable. The .556 NATO cartridge has higher pressure and velocity than .223 Remington, which can cause issues if the wrong ammunition is used in a firearm chambered for .223 Remington. Both calibers are popular for target shooting and hunting small game, and are also used by law enforcement. Another popular caliber for AR15s is 308 Win, which is a larger caliber that is popular for hunting larger game.

There are many great brands that manufacture AR15 rifles, including Colt, Smith and Wesson, Ruger, Sig Sauer, Springfield Armory, and Daniel Defense. These brands offer high-quality firearms that are reliable and accurate. However, there are also value brands like American Tactical Imports and Radical Firearms that offer high-quality yet affordable options for those on a budget.

Over the course of this 3-part blog series from GrabAGun.com, we will cover the different brands and different models of the AR-15 rifle, as well as accessories and upgrades that can be added to enhance their performance.

A Little Backstory…

Daniel Defense began back in 1999 when founder Marty Daniel visited the shooting range for the first time. Immediately, he fell in love. He found that shooting was the perfect stress reliever and his engineering mind quickly went into overdrive. Daniel began wondering how to grow, innovate, and enhance firearms everywhere. Thus, the company we know today, Daniel Defense, was born. 

In the years that immediately followed inception, DD came up with some truly groundbreaking products, including the “Big Hole Upper”, Sling Loop, and reliable rail systems, to name a few. What sealed DD’s fate was acquiring a contract by the Special Operations Command (SOCOM) in 2003. DD beat out larger manufacturing companies, solidifying their place in the industry. 

Not resting on their laurels, Daniel Defense went on to manufacture the DDM4 in 2009. They have been recognized as one of the fastest-growing private companies in the USA, with a 1000% growth rate over a ten-year period. Don’t let their young age fool you–Daniel Defense is the name best associated with modern AR15 guns for sale.
