AR-15: Fixing Common Problems & Using Ejection Port Covers

The AR-15 style rifle is a seriously powerful and amazing machine. It is designed to pop off dozens of rounds per minute, and can fire even more if it is modified. Those last few words reveal perhaps the most astounding aspect of the AR-15: it is also highly customizable. The rifle’s design is versatile enough that it can accommodate many different kinds of add-ons and upgrades. These can imbue it with even more power, range and ease of use.

With this customization comes complication. Novice users need to be careful if they have never fine-tuned their rifles before, or they risk turning their marvelous shooting machines into dysfunctional duds. On the bright side, you can do something about it with the tight equipment and know-how. Here is some information on how to resolve common problems with AR-15 upgrade.

Common Problems with AR-15 Rifle Upgrade

When new AR-15 owners discover the rifle’s potential for customization, they get as excited as a kid in a candy store. However, swapping out different components may be a bit trickier than it looks. If you plan to modify your gun, you should at least learn how to do it right — or you might end up with a major downgrade instead. Here are some of the common problems you might encounter if you try to upgrade your AR-15.

Getting Parts of the Wrong Sizes

Experienced rifle owners are always looking at specifications. These details may seem small, but they can make a world of difference. Unfortunately, this is something that many people only learn through experience. Too many overeager gun owners shell out a hefty amount of cash for a high-end upgrade part — only to discover during the attempted installation process that it is too big or too small or just plain incompatible.

When looking at upgrades, make sure to first look at the specifications for your rifle, then at the specifications for the upgrades. This could mean anything from the threading of a muzzle to the diameters of hammer pins. It may sound a bit tedious and take more time, but it can save you a real headache in the long run.

Issues with Swapping Handguard Rails

Sometimes, the problem is not with finding the right size but with finding something that is even compatible with your model. For example, among the first adjustments that many people make to AR-1s is with the handguard rail. Rifle manufacturers include a standard handguard rail with their rifles because they allow people to hold the gun from the front, for better balance, without having to touch the hot barrel. These might work well enough but, some still prefer switching them for more comfortable or versatile options.

You can find plenty of handguard rail assembly systems out there. However, these systems can come in many shapes and sizes and lengths, and not all of them will work with your rifle. Some can be used for multiple distinct models while others are more specific and exclusive to one company or type. You need to evaluate all the choices carefully before making a purchase. See if the screws and base rails would even work with your rifle of choice.

Advantages of Ejection Port Cover

Although we detailed a few of the more common problems with AR-15 upgrades, we only mentioned them so rifle fans can know what they are getting into. We still encourage people to give them a whirl anyway because they can be highly beneficial. An example of a great upgrade is the ejection port cover for AR-15s. Here is some information on what makes it so great.

Keeps Dust from Settling Inside the Barrel

The ejection port is an open hole on the gun that allows bullet cases to escape after they split from the action. You definitely need that hole if you plan to fire your weapon, but it cannot simply be left open when you are not using the gun. Otherwise, that leaves an opening for dust and other particle matter to settle. Too much of that natter will cause your gun to stop working properly.

If you don’t like the idea of the mighty AR-15 being rendered a hunk of junk, you need to make sure that it is protected from the elements. When you are not using your own AR-15 style rifle, make sure that its election port is secured from dust with an ejection port cover.

Keep the Elements Out of the Gun

When you are actively firing your rifle, you should leave the ejection port open so the bullet cases and gases have a way to get out of the gun. However, this does not mean you should leave the cover at home. You may want to keep it covered while you are out and about, and while you are simply holding or toting your rifle.

This especially goes for when you are hauling the AR-15 through environments where mud and dirt and other gunk can get all over the gun. Hunting, for example, can be quite dirty, especially if you are planning to camp. The great outdoors is not great for keeping guns clean. The least you can do is to keep the port cover handy for situations like that.
