AR-15

While they may be known for their M1A rifles, 1911s and XD pistols, Springfield Armory has just jumped into the AR world with the new Saint rifle in 5.56mm. Take a look at our mag dump torture test and full review of this exciting new firearm.

Get a behind-the-scenes look at the Springfield Armory Saint release event in Las Vegas, where we put the rifle through its paces in a variety of CQB, tactical and long range situations.

This week, on adventures in amateur gunsmithing, we acquired a basic M4 Carbine-style AR kit for a DIY AR build project. The kit comes with a complete upper receiver and a lower parts kit. All you need to supply is a lower receiver.So, come with us on this DIY journey on home building our own AR!

Many factors go into how a weapon functions and the ballistics of your chosen projectile. 5.56 is absolutely fine as a combat cartridge. As long as you can move the bullet fast enough. But, is there a better option for all the other situations?

When it comes down to it, the AR is a highly established and popular design. But, that does not mean there is no room for improvement. And if you can do that and still make it affordable, then all the better. The new an improved M-Lok MMR might just fit that bill.

One of the most popular replacement AR triggers on the market comes from the good folks at Geissele. They have been building some of the best triggers available since 2004 and show no signs of letting up, and one of their more popular (and affordable, priced at $165) triggers is the G2S.

Based on sales figures and some good, old-fashioned SWAG math, there are somewhere in the neighborhood of 10 million AR-15 rifles floating around the country, give or take a couple of million. And guess where all that AR popularity started? Armalite.

While it seems like just about everybody is making the AR, the name Colt still carries a lot of weight when it comes to this design. They were the “first” in the minds of many civilian shooters, and the company has a long history of producing the design’s martial sibling for the U.S. military. And now, with the M4 Expanse, Colt is offering a great gun at a great price.

Today, everyone in the industry is aware of the 300 BLACKOUT cartridge. Indeed, firearms and ammunition in 300 BLK are readily available from most major manufacturers. However, many readers may have forgotten, or never heard, the origins of the cartridge. And the company that developed has its own AR designed to fire it.
