AR-15s are pretty much pinned together. While a staple for many AR-15s, roll pins are not hard to work with, but a misstep could be catastrophic enough to permanently damage your AR-15. Here’s how to perform the essential construction operations associated with roll pins—the professional way.
When something goes wrong and the rifle won’t fire, the first question should always be, “What changed?” Before answering that, we have to determine—or at least I determine—whether we’re talking about a “fresh” rifle going through its shakedown period, or a (previously) trusted gun that’s suddenly decided to stop running. If it’s the first scenario, there’s a longer list of possibilities that include original parts, conditions, and installation quality. This article will focus on the previously-functioning rifle that’s taken a vacation from operation.
We’ve chosen the sometimes twisting path to becoming handloaders because we want to improve on-target results. The difference between a handloader and a reloader? My wise-crack answer, which is honest, is that handloaders start with new brass… We’re not about to shoot factory ammo.
Don’t short-change a short gun! When you spec a carbine, think about shooting it! Simple? Yes. But don’t adapt to the carbine; make it adapt to you. Here are a few thoughts on how to get the most utility from your carbine.
The magazine is a part of the rifle, and it’s a moving part. The magazine feeds the daggone thing its rounds so it can fire its bullets. That’s how important the magazine is.
Bear with me! We’ll get started on the process of handloading next time when I talk about setting up a sizing die. But before that, it’s good to keep in mind what we’re dealing with, and that is a cartridge case, and also what happens to it during firing, which is what we’re setting out to remedy when we reuse it.
Semi-automatic rifles and bolt-action rifles are related but far from the same. When handloading, it’s helpful to realize they are not to be approached the same way.
A barrel-twist rate is expressed in a chain of numbers that reflects on how far down the barrel a

The AR-15’s bolt and carrier are the heart of the rifle, so knowing the ins and outs of the bolt carrier — weight, platings and coatings, firing-pin hole size and bolt choices — can make your AR run more smoothly and reliably.
