BLOCK THAT RECEIVER

Just don’t get flagged for holding.

- PATRICK SWEENEY

Handling an AR-15 lower— while also assembling it, tightening something or just making it behave—can be a hassle. Midwest Industries (MI) has a solution, and their lower receiver block serves you in two ways.

First, you can simply slap the block down on your workbench and fit the receiver into it, nestled in place. It’ll stay put while you install the hammer and trigger pins and the trigger guard, even making it stay put while you hand-screw the buffer tube in place. (You’ll need more than the MI block to do the torquing and staking.)
