Smart-fit is a very nifty lower vise block with a cool looking grey and red design. It has an expanding design thanks to which it fits well and securely in any AR-15 magazine well. The Smart-fit vise block is made to eliminate any rattle and movement that is typical among one-size-fits-all blocks.

This vise block is made from a sturdy and durable polymer. To ensure a solid, immovable fit, simply insert the block into your gun’s magazine well and rotate the adjustment handle until it is tight. This provides for a secure mounting point that holds your AR-15 in place while you work on it.

You can use this block in a vise from the top or bottom of your AR-15. You can also use it with two hands without a vise when working on inverted lower receivers, pistol grips, trigger guards, and other components on the bottom of the receiver with ease. This vise block also includes the company’s Pivot Lock, allowing users to access the barrel and chamber of their guns hands-free.

Magpul Bev Block – AR15/M4 Mag536

Magpul Industries is a US designer and manufacturer of high-tech polymer and composite firearms accessories. The company is based in Austin, Texas. Magpul does not have a written warranty but their customer center will help you out anytime you have a problem with any of their products.

Recently, Magpul has ventured out into quality gunsmithing tools and the Magpul Bev Block is part of it. Bev stands for barrel extension vise. This vise block can replace multiple tools as it can hold a lower as well as your favorite upper receiver. Its body is made from nylon polymer. There is a steel insert inside the body and an o-ring on the side that interfaces with the carrier for added rigidity when you use it with an upper.

Place the Bev block into the vise with the narrower part down and you can use it as a vise block for your AR-15 lower receiver. It fits great from the top as well as from the bottom. When you flip the Bev block in the vise, you can use the narrower part to engage the barrel extension in the upper receiver. You can tighten the barrel extension on the Bev block with a pin.

The only complaint we have is that there is a little wobble when working on your lower but you can get used to it.

This lower vise block is made from heavy-duty urethane plastic. That makes it sturdy and durable, keeping your AR-15 rifle secure for safe, effective cleaning, assembly, and repair. The block won’t be destroyed even when applying strong vise pressure or torquing the barrel nut heavily. You can insert the block into the magazine well from the top or bottom and clamp the other end of the vise block in your bench vise jaws. The magazine catcher keeps the vise block safely and securely in place. The vise block does not leave any marks or scratches.

The only downside of this product is the fact that it cannot be used “out of the box.” It requires some filing to fit. The material is a solid, milled urethane that is very tough to file and you will need a heavy-duty file to get this to the size you need. Also, when you file it to fit on one lower receiver it might not fit another one.

This lower vise block has a simple design which does the job. Budget shoppers will appreciate that the price is affordable. It does not require any fitting and it is easy to use. You will need to have your own vise to use this lower vise block though.

This lower vise block is also suitable for two-handed manipulation and adjustments to your rifle or AR pistol without having to hold it in a vise. There is, however, a downside to this vise block. When you are torquing the buffer tube onto your lower you have to be careful not to use too much force or the vise block might break in half. It is a little bit more brittle than expected.

This vise block has a simple design that makes it easy to use. It is affordable but not the cheapest for what it has to offer. However, it has only one size and the magazine wells on AR-15s might not always be the same. That means you can experience a slight wobble when working on your AR-15.
