Now, assembling a lower receiver is significantly easier 보다 an upper receiver. The entire cause group, safety and security lever, mag release, bolt capture can all be set up with little much more than one Allen wrench or two, a pin punch, and also some Locktite.

Again, this isn"t rocket science however there space tricks. Mistake can selection from embarrassing come disastrous. World in the an initial group will probably stop analysis right here and opt to scroll back up and also order a finish rifle, and that"s okay. However, human being in our second group of do-it-yourselfers will likely take this as a challenge.

Want a details Logo/Style on top or Lower

The next thing to take into consideration is ease of access and your preference. That course, there are AR-15 parts obtainable by the trainload, but are lock the ones that you want? because that instance, you uncover the perfect reduced from brand A, yet they don"t have actually an upper receiver without a front assist. You"re going because that a sleek, ultra-light build and also don"t feeling the need for a forward assist. In this case, you will either change your construct or discover the top you desire from another manufacturer. This can easily go the various other way. You desire a timeless look and also you wouldn"t have a rifle there is no a front assist, but brand A doesn"t sell one. Right here again, you room going to acquire what you desire from the agency that uses it even if that way using two different brands.

Some manufacturers market some quite wicked lowers that have actually designs made right into the mag well. What if castle don"t have actually the top that fits your build or budget? perhaps you want a particular logo to show up on your rifle. Friend can find it, but that brand doesn"t bring the other half of the recipient in the architecture you want. This is another reason come mix that up.


Dual Tone

For some people, the shade or ton of a rifle means a vast deal. Not as soon as it pertains to pretty accents however to the in its entirety look. Through the AR-15 girlfriend don"t need to keep the same tone throughout the build. Friend will uncover that various manufacturers offer different color choices for one AR upper and lower to fit your an individual taste.

Maybe this isn"t something girlfriend have ever considered. However, at some point you could see a rifle in a newspaper or in ~ the variety and it"s every done increase two-toned and you say why not develop one like that. Might be the you join a club or begin one yourself where everyone has matching weapons. There"s naught wrong through that. One certain upper comes from one manufacturer and also the reduced from another. This is yet one more reason the might reason a person to mix and also match their AR upper and also lower receivers.

Can any type of AR-15 upper Fit any AR-15 Lower?

Now comes to the question of whether any AR-15 top receiver will certainly fit any AR-15 lower. The prize is almost. Be affected by each other in mind that the AR-15 has been around for nearly six decades. Over there is no telling how plenty of different manufacturers have cranked the end these guns, and there is no regulation to manage them. Except for the one small term, that term is Mil-Spec, execute remember this due to the fact that it will certainly be top top the test. That stands for armed forces specification, and also it lays the end the dimensions and also tolerances that are acceptable for the details item. Now, unless someone offered it to me, ns wouldn"t shot parts from an unknown source. However, any component sourced from a respected manufacturer that is designated together Mil-Spec must physically walk together. One well-known exemption is v Colt rifles made before 1991 and also after 2009. During this duration Colt draft their firearms to use smaller sized takedown and pivot pins. Maintaining this exception in mind, feel free to resource trusted parts and build away.

Will mix Upper and Lower recipient from different Brands influence Accuracy?

There are some civilization who preserve that a gun is going come be much less accurate if you carry out not use the same AR-15 match upper and also lower receivers. This thought is patently untrue. If girlfriend bear with me for a moment, I will certainly logically prove this out.

The primary function of a reduced receiver is to house the fire regulate assembly, magazine, and to organize onto the upper. Ns know, there space other tiny pieces in it, but it yes, really just gives you something to cave onto. It"s in the top receiver whereby all the magic, or physics, happen.

Accuracy is attained or lost within the interface of your BCG, barrel, and handguard. Additionally, the length and also grade the the barrel room vitally important. Now, if you incorporate a high-end reduced receiver v a bargain basement, scrub top then girlfriend would have actually a allude of degraded accuracy, yet who would perform that? No, combine upper and lower receivers of various brands will make no difference in accuracy whatsoever. ~ above the other hand, the high quality of your upper receiver absolutely will.

Things to Consider before Mixing Upper and Lower recipient from different Brands

Okay, we have established that because that the most part, AR upper and lower receivers from various manufacturers will certainly physically fit together without affect accuracy. Now we involved finish, this might be no big deal or a transaction breaker. Either way it walk depends entirely on her individual perception and also tastes.

Anodizing color Might not Match

Anyone that has ever tried to complement the shade of paint in your house, or on her car, knows that there are about a million different shades of any kind of one color. Black have to be black, yet when the two components go side by side, also a slight distinction is noticeable. Even something as little as pins, security selectors, mag releases have the right to have a small, but significant, color difference that will stand out. Climate there comes the anodizing process.

Every manufacturer does no necessarily adhere to the same procedure when lock anodize your aluminum parts. Therefore, once you resource parts from various manufacturers the result colors may be just a little bit different. If you take place to obsess end the slightest variance in color and also contrast this could be an issue. However, even time can adjust the color of a specific manufacturers components. This is a reality examine here. As technology improves and also companies progress, so carry out their procedures of anodizing parts. So, say you bought an upper from one manufacturer today and a lower from the same company next year castle still may not exactly enhance in color because their procedures have changed. Ultimately, you will certainly probably notice it much more than everyone else, kind of like a teenager v a pimple top top the method to the Prom.

The Style might Not Match

Another consideration for her AR upper and lower recipient is the process by i m sorry it was made. You have two choices, either one that is forged or one the is machined indigenous an aluminum billet. There room valid points to it is in made on both fronts as to strength, durability, and accuracy. The purpose here is not to support one over the other, merely to allude out the viability of mix an AR-15 match upper and also lower receiver.

The major thing that stands out between the two is the price. Uneven you stumble onto a great bargain, the forged recipient is constantly going come be lower in price. This is no necessarily because it is an inferior part, but due come the process of manufacture. Forging a recipient takes much less time to complete, and time conserved is money saved.

However, here we go earlier to finish. A receiver that is machined native an aluminum billet, usually has a cleaner, prettier complete than one that has actually been forged. So, you deserve to save a tiny and opt for a forged lower receiver, placing that savings toward a higher grade billet upper. You will certainly probably be able to see a difference in the end up when the upper and also lower are mated. But, choose the teenager with a pimple is it going to issue to you.


There is one ongoing conflict when it pertains to the AR-15 as to how loose is too loose when it considering upper and also lower fit. Remember, this communication is draft to it is in quickly and also easily bring away apart and also modified. If her AR-15 isn"t a bit loosened when you build it, simply shoot it and also it will ultimately get the way. If you want a rock solid, precision fit climate forget all about an AR-15 and also go purchase a bolt- action. However, let"s talk for a minute around our perception of loose and tight.

The AR-15 has actually an upper and also lower receiver that is made from some kind of aluminum. The takedown and pivot pins space usually going to be either stole or titanium. Considering the abuse that recoil and also wear native breaking under your weapon for also normal cleaning, the fit will loosen. Is the activity measurable through a feeler gauge or v a ruler? Remember that the accuracy is emerged in the upper and as long as the weapon is safe to fire then lock and load.

That gift said, you will find that AR upper and lower receivers will differ in exact fit in between different manufacturers. The doesn"t average that they won"t fit. Just that you will certainly run right into some that are simpler to put together 보다 others. As lengthy as the receivers room Mil-Spec, they have to mate. After structure a few, most civilization find a certain brand lock favor. This doesn"t median you shouldn"t try something new. There space shims commercially accessible to tighten the fit between the upper and also lower if it really bugs you.


Putting with each other a working AR-15 indigenous a heap of parts can be a one-time experience, a rewarding hobby, or even bloom right into a business. For rather a few people it starts with the an easy idea that I deserve to take two various things and also make one beneficial thing. Also if that doesn"t wind up being all the you expected, there"s no really a downside. If you obtain your parts from a trusted source and perform them no harm, over there is a huge an additional market that is hungry for her leftovers. Additionally, if you"re no careful, friend just could learn something.
