​Key Factors to Consider

1. Quality Control

The rifle industry has some of the most stringent manufacturing laws. Quality control needs to be considered and there are guidelines to ensure this happens so. It is therefore the prerogative of the buyer to ensure that they don’t put their hands on products that haven’t been able to adhere by such rules and specifications. What resources have they committed in design, manufacture and shipment process to guarantee the facility will be free of defects.

2. Adherence to Laid Quality Standards by the Company

​Have you ever heard of the term Mil-specs? If you are in the receiver filed, you must have heard of this before. If you are new, Mil-spec is a great feature for marketing. Ensure that the company advertising their product as Mil-spec isn’t saying just half of the truth.

​a) Specifications

There are some most common specifications that you should look for in these products. If a manufacturer is not able to produce high quality products in any of the specifications, you can as well avoid doing business with them.

  • Has the gas key been properly staked
  • Has a magnetic particle (MPI) inspection been done on the barrel and bolt?
  • Has the barrel and bolt undergone high pressure testing (HPT)?
  • What durability features does the product have? The best AR 15 lower receiver will always feature a sturdy construction using durable materials such as aluminum and stainless steel etc. they also have to be lined with chrome, nitride-barrel and such like materials and finishes among others
  • Shot-peened bolt and barrel
  • Is the product Mil-Spec?
  • Does it have a 5.56 chamber?

These are some of the questions, though not exhaustive that when answered, you are so many steps closer to grabbing the best AR 15 lower receiver your money can give you.

b) The Mil-Spec controversy:

If your product isn’t mil-spec, I want to assure you that it will have more faults than you can imagine. The product will have a poor staking on its gas key. It will have a softer 4140 barrel steel or something worse. The bolt will stress you up and you will get no value for your money. You need to think of the mil-spec features as your shopping benchmarks.

Let the manufacture tell you that the product has been chrome lined. If he doesn’t mention this, assume it isn’t chrome lined and move forward. Let them tell you that the bolt and barrel are shot-peened, HPT and MPI. Similarly, if they are silent on this, your assumption should always be they don’t meet those standards. And the material used in the manufacture has to be mentioned as which type of steel. The best AR 15 lower receiver will also always have a 5.56 chamber which implies that it will be capable of safely shooting both the .223 as well as the 5.56 itself. You may alternatively want to go for the .223 Wylde chamber, which is also acceptable.

3. Customer Service

Even with the best possible care, occasionally a product may have some faults. Even without faults, there comes a time when you probably may just need some guidance on how to use the product. Companies that have been credited for having some of the best AR 15 lower receiver will always be there to correct any quality issues if they occur. In other words, the companies have valid warranties and they live by the word of their warranties. What are the former users of the product saying about the customer care in their reviews?

4. 80% Lower or the Stripped Lowers

80% lowers are 80% to completion. They are fast growing in popularity, thanks to the fact that no federal transfer regulations such as AFT Form 4473 filling and the FFL transfer. On the other side, Stripped lowers are 100% complete and can only be shipped upon filling the transfer federal regulatory forms.

5. Billet, Cast or Forged

The best AR 15 lower receivers are not limited to a specific material type. Just ensure that the manufacture presents you with the critical metallurgy test results so you can ascertain that the product is capable of standing up no matter the purpose or operation.

6. Warranty

You need to ensure that you have the best possible warranty in the market. If the product you want to buy is an 80% lower, the warranty must be unlimited and in most cases, lifetime. On the other side, some of the parts of the stripped lower will come with shorter warranty, say 2-years, with other parts coming with extended warranties.

​7. Durability

Other than just the material used in construction, also ensure that the finish on the surfaces of your receivers are those that have been proven to withstand wear, tear and scratch among other factors that would jeopardize the durability of the product. This is of course in addition to the sturdy construction of a lower receiver that you must choose.

​8. Lightweight

Heavy guns can be cumbersome and tiresome to work with. It can also be quite difficult to hide or rather conceal such guns. It is therefore a necessity that you go for lightweight guns. A lightweight lower receiver is a prerequisite of a lightweight gun. As a result, some of the very best AR 15 lower receivers are those that will weigh around 5 ounces but not going beyond 8 ounces.
