What Makes A Quality 80% Lower Jig

Before you shell out the hard earned cash for an 80% jig, there are a few things you should consider. The overall quality of the jig you purchase will make a difference in your completed AR-15, both operationally and aesthetically. Insuring your 80% jig is quality will be time well spent. Here are a few things to consider when purchasing an 80% jig.

  1. What Material Is It Made From?

The first item of consideration should be what type of material the jig is made from. An 80% jig should be made from material that is durable and will be suitable to finish a multitude of lower receivers. AR-15 Lower Receivers prides themselves in manufacturing their 80% jigs from 6061 aircraft grade aluminum. We believe both our jigs and your AR should reflect superior performance and ease of use.

  1. How Tight Are The Tolerances?

The tight tolerances of the 80% jig will insure both proper fit and function of your AR’s fire control group. Before you purchase your 80% jig, ask the manufacturer what tolerances held to when the jig is in the manufacturing process. Each AR-15 Lower Receivers 80% jig offers a +/- .001 tolerance. For illustration sake, a human hair measures around .005. When the integrity of your AR is on the line, we’re not interested in offering an inferior design.

  1. What Warranty Is Offered?

A reputable jig will come with a solid warranty. Be sure to ask the manufacturer what their warranty offers, along with the details of their return policy. There’s no reason for you to have any issues that cost you money you’ve worked hard to earn. Each 80% jig offered by AR-15 Lower Receivers comes with a 100% satisfaction guarantee. (Yes, you read it right!) If for any reason you are not 100% satisfied with the product, you can return it to us within thirty days for a full refund. How’s that for service?

  1. Does It Include Step-By-Step Instructions?

  1. Does It Come With Customer Service? (In English)

If a company sells you something, they should also service it! Maybe we’re old fashioned but we still believe if you have an issue you should be able to talk to someone from the company. Before you buy a jig, find out if you receive any type of Customer Support with your purchase. We still believe the customer is #1 and we promise to take the time to answer any questions you might have. This means we offer live phone support if you decide to purchase one of our 80% jigs.
