What is the PRO MAG - AR .308 Lower Receiver Magazine Well Vise Block?

Whether you're building an AR-style .308 rifle for the first time or performing cleaning and maintenance on your extensive collection, having a vise block for your workbench is a must-have. This simple tool provides a dedicated mounting point for your short-action rifle, allowing you to use both hands for parts installation and detailed cleaning. Each AR .308 Magazine Well Vise Block can be clamped into a user's workbench vise, allowing users to insert their lower receiver onto the exposed section of the block for a solid, secure working point. The block itself is made from injection-molded polymer and is made in the USA. The unit is designed for use with Armalite, DPMS, Remington, SR-25 and other popular lower receivers.

A solid buy
I bought this vice block to make it easier for me to clean my gun however, I found so many more uses for it. I use it to dry my gun after I’m out hunting with it, I’ve used it to mount my optics, and I’ve used it to mount other accessories as well. It’s a must have for a 308 or AR 10 gun Cleaning.

Versatile and great value
Plastic seems rugged, price is great, fit is fine. Stop prevents lower from dropping onto vise and mag catch engaged well. The 2 ends of this block are NOT the same. One is for DPMS pattern and the other for Armalite. The reviewer who couldnt get the mag catch engaged was using the wrong end. My Aero Precision M5E1 lower fit very nicely and the mag catch engaged. (Brownells description doesnt explain this and the lettering for the different ends is hard to see.)

Very versatile tool
This block seems very handy to me. I handle a lot of guns everyday and I shoot almost every day and for the money, the 308 jig has fit everything I have put on it.
