Builder's Corner: The Bazooka Green Build

Builder: Keith G., Primary Arms Customer Service Assistant Manager It all started with a gold sharpie, and a conversation with a coworker who likes to enable me when I have ideas for new builds. I had an Aero Precision receiver set and a handguard that were Cerakoted in a bazooka green color. Why that color? I cannot say specifically, other than the fact that it looked like the old plastic army men toys we all used to have growing up and I thought that would be cool. But also, really ugly and a good conversation rifle. So, I set out to build an ugly AR-15, all bazooka green, just for the heck of it. Then I talked to Colin, who is never short on ideas – some of them are even good! My ugly build was about to reach truly epic levels ...[ Read More ]

Are AR-10 and AR-15 Parts Interchangeable? [Builder's Corner]

Think of the AR-10 as the AR-15’s big brother. A little older, a little stronger, and taught little bro’ everything he knows. The AR-10 was designed around the 7.62x51mm NATO rifle cartridge. The civilian version of this cartridge is the .308 Winchester, introduced in 1952. While factory loadings and hand-loaded .308/7.62x51mm rounds are still the most popular options for the AR-10 today, new calibers like the 6.5 Creedmoor are quickly gaining widespread adoption for use in the AR-10 platform, leading to a marked rise in the platform’s popularity. The AR-15 was designed for a smaller round, the 5.56x45mm NATO cartridge, and conceived a few years after the AR-10. The smaller caliber allowed for the design of the rifle itself to...[ Read More ]

.224 Valkyrie vs. 6.5 Grendel: Battle of the 1,000-yard AR 15

Your AR-15 is a ton of fun at close range. Punching holes in cardboard, demolishing milk jugs, pure semi-automatic joy as fast as you can take aim and pull the trigger. But you get no respect from the precision bolt-action rifle shooter at the range who says, “you can’t hunt with that thing anyway,” or “you can’t hit a barn door at 700 yards.” He throws you a smug look before settling in behind the wood stock of his prized bolt-action. When he fires, there’s a pause of silence, then “ping” as you hear the steel ring from THAT gong. The one you’ve never even tried to hit with your AR-15. The one that’s 1,000 yards away. But what if your AR-15 could make that shot? What if it was capable of a one-shot takedown of game animals all the way up t...[ Read More ]
