2 pack CNC 3/8" End Mill Kit for Milling the Firing Pocket and Mag Well on AR15/AR10 Lower Receivers
AGT's proprietary "F23" coating for extreme wear resistance and lubricity.
These end mills deliver improved performance and have set a new benchmark for machining the firing pocket and the mag well.
The combination of our extended length 3/8" rougher and 1/4" finisher
is a GAME CHANGER.
Before now there has never been extended length end mills rigid enough
to efficiently machine the mag well from one side.
AGT's new design has overcome that obstacle.
With a simple pilot hole hole through the middle you can now
rough and finish from one side, with a perfectly smooth finish all the way down
to the bottom of mag well. No more flipping the lower on the fixture.
No more ugly mismatches and hand blending.
Just a finely machined lower receiver that you can be proud of!
