What is the BROWNELLS - BRN AR-308/AR-15 Lower Vise Block, Black?
AR-15 LOWER RECEIVER VISE BLOCK


Working on your lower receiver just got easier.


Brownells is dedicated to providing gunsmiths, armorers and gun owners with the right tools for the job, our AR-10/15 Lower Receiver Vise Block is no exception. Made from non-marring polymer, our vise block will hold a lower receiver securely featuring an anti-wobble feature in a bench vise, like the Brownells Bench Vise. Our Lower Receiver Vise Block uses a magazine catch groove and is compatible with most AR-10 and AR-15 lower receiver magazine wells. Changing lower platforms is as easy as flipping the vise block over. This is a must have for anyone serious about working on AR platforms.

Great idea
Don't know why this wasn't created long ago, 1 Vice Block for AR10's and AR15's - what a great idea. And the internal clamp (anti-wobble lever) is a plus.

I have several other types of receiver blocks but this one is solid. Read the review for a tip.
This block locks the receiver solidly in place. The only issue is you have to loosen the vise to release the receiver which is a bit of a pain because the block does not stay in place. Therefore, I install the block so that the metal squeeze plates are positioned above the vise jaws. Then, I use a clamp to apply pressure to the squeeze plate, which holds the receiver solidly in place. It works great.
