The Buying Considerations for The Best Armorer’s Wrench

Price

If you opt for some of the cheaper AR-15 armorer’s wrench out there, it might last you for only 1 AR-15 build. However, getting a great wrench will not break the bank, therefore you shouldn’t have any problems finding a great AR-15 armorer’s wrench with a $50-$80 budget.

Brand

Both the price and brand of an AR-15 armorer’s wrench is crucial. You should always stick to buying products that are manufactured from companies that don’t compromise on the wrench’s construction. Also, you should also make sure the price is justifiable as some well-known brands have come out with mediocre wrenches with a premium price tag.

Ease of use

As with any other product, you should always ensure that the AR-15 armorer’s wrench that you’re looking at is easy to use, handle, and store. You wouldn’t want your AR-15 building experience to be a total nightmare. The more frequent you work with guns, the easier to use your armorer’s wrench needs to be.

Safety

There are plenty of manufacturers that don’t really pay much attention to upgrading their AR-15 armorer’s wrench with having an ergonomic design. The preliminary design would ultimately lead you to more discomfort as you work on your AR-15. In some cases, you might even end up injuring yourself.

The rule of thumb is, whether on or off the range, safety is always first. A poorly designed AR-15 armorer’s wrench will not hesitate to hurt you and leave marks or scuffs on the surface of powder-coating of your AR-15.
