What is a Lower Vise Block and What Are They Used For?

A lower vise block is used when you are looking to make necessary repairs or installations on your AR-15 rifle. It is a heavy-duty block designed to firmly hold your rifle in place while preventing the rifle from getting crushed, twisted, or damaged in some other way. It is also guaranteed not to leave any scratches on your rifle in the areas where it’s held in place.

How to Choose a Lower Vise Block

As you’re choosing a lower vise block, you should consider a few aspects that will determine your final purchasing decision. These are the same aspects we’ve considered while finding a vise block to add to our list of reviews. The only difference is, you’ll need to choose one. With that said, here’s what we recommend you look for as your search progresses:

Price

If you’re a budget shopper, you’ll probably hold the price tag to higher importance. The cost should not be the only reason you choose a lower vise block, though. You should pay attention to the overall quality and function of the lower vise block. This way, you can determine if it’s excellent in quality or if it’s a cheap, low-quality model.

Material

The overall quality will depend on the kind of materials being used. Most materials that manufacturers use for these lower vise grips will be either aluminum, steel, or polymer. While they’re best known for being durable and impervious to damage, they also are the best materials to use when you want to protect your lower receiver from any scratches, scuffs, abrasions, or other types of damage.

Adjustments

Lefty loosey and righty tighty. Those are the words that are stuck in our heads when adjusting our vises. The question you need to ask is: how easy can it be to achieve a secure grip? Find a vise block that will allow for smooth and easy adjustments. At the same time, you’ll need to make sure that while the vise is tight enough, it won’t be able to crush or seriously damage your AR-15 rifle.

How to Use a Lower Vise Block

Using a vise block can be a challenge if you have no clue on how to use it. But if you follow the simple instructions below, you’ll be able to use one like a pro in no time. Here’s what you need to do:

As always, safety first. Check to see if you are free and clear from any live rounds. The magazine well should be empty, as well as the chamber. Once you’re clear, disassemble.

Take the lower receiver and using the mag well, slide it through the lower vise block. You have the option of sliding it in either the inverted or upright position.

Disassemble any parts that may be still assembled in the lower receiver itself. Or if you’re using it to clean the lower receiver, use any cloths, oils, or solvents that you use and clean thoroughly.

Once finished, reassemble everything and double check that all parts are secure.
