The Easy Jig Gen 4 can convert a compatible, previously milled lower to an M16-style pocket, providing the additional clearance needed for compatible FRT setups.

It also handles AR-15, AR-9, AR-45 and DPMS Gen 1 .308 lowers, giving you more build options from one jig.

New build or existing lower, the Gen 4 is ready to go back to work.

Just wanted to show some love for the Smith Defense S365 grip module.

One of the coolest parts about it is the modularity. Being able to swap configurations and tailor the setup to what feels best in your hands makes a huge difference.

The texture feels solid without being too aggressive, the ergonomics are clean, and overall it just makes the platform feel a lot more refined and customizable.

Cheese graters are a common household kitchen utensil.

Unrelated to grating cheese, but have y'all read up on the latest Colorado court ruling that addresses firearm frames and receivers in the broader context of "ghost guns"? It's pretty interesting. Here's more info: https://usconstitution.net/court-says-the-second-amendment-covers-firearm-parts/
