It’s true: 300 AAC Blackout is, in fact, almost universally superior to 5.56 NATO and .223 Remington. We’ve got the ballistics data to prove it, too. There’s just one, specific circumstance in which 5.56 or .223 is “slightly better”, which we’ll cover below. So, if you’re on the fence about which caliber to chamber in…
We sell a lot of AR-15 jigs and AR build kits. So, we’re f requently asked which lower receiver’s better for building an AR: Billet or forged? Plenty of builders will tell you that it’s entirely up to personal preference — that both types of lowers are basically identical when it comes to performance. That’s…
Does your AR-15 feel like it produces excessive recoil? Or do you frequently wind up with short strokes and jammed casings? Your AR-15 might be over-gassed or under-gassed. You might need to swap your gas system, or install a lighter or heavier buffer. Thankfully, there’s an easy way to figure all this out. You just…
The 9mm AR, officially called the AR9, provides a compact solution that allows the AR platform to ditch its gas system and, more importantly, its buffer system. One of the stubborn pains the AR-15 and its many variants suffer from is the buffer tube. It’s necessary for the bolt carrier group to cycle properly. Well,…
We recently covered how to register a short-barreled rifle with the ATF, as part of the National Firearms Act (NFA). One of the most important — and, for many, complicated — parts of the process is acquiring a set of fingerprints to provide with your Form 1 or Form 4 application. But getting fingerprints taken…
So, you’re ready to ditch that 16″ upper and pistol brace. Or maybe you’re building a fresh rifle from scratch, and you need to register your receiver before you install a buttstock. Here’s how to register a short-barreled rifle (This Covers Form 1 SBRs) Note that these instructions cover how to file a Form 1…
Bought a match-grade barrel? Assembling a long-range .308 setup with a stainless target plinker? The build quality of your barrel comes first, but the quality of the upper receiver you install it in can be just as important — especially if you want proper optic and iron sight alignment with as few adjustments as possible…
We recently covered why dwell time is so important for your AR’s ability to cycle reliably. The length of your gas system determines dwell time, which determines how much gas flows into your bolt carrier group to cycle the action. Too much gas causes excess recoil and wear and tear. Too little gas makes for…
There are a lot of AR-15s running the wrong gas system length, which can make your rifle, SBR, or pistol unreliable. The wrong gas system can can cause excessive recoil and increased wear, or it can cause short strokes, poor cycling, and frequent jams. If your AR’s suffering any of these issues, the most likely…
With more than a dozen models available — and with different models sharing grip modules, slides, barrels, and calibers — figuring out the P365’s dimensions, and which model you may want to configure or buy can get confusing. We’ve collected the dimensions for all models to make it easy! P365 Models & Dimensions Models are…
