Aero Precision M4E1 Freedom Special Edition lower has the patriotic engraving on the magwell. Otherwise its the standard M4E1 with reinforced trigger guard area and tighter tolerances than a basic forging. Mate to my M4E1 upper has zero play.
the freedom edition cerakote is well applied, no light spots i could find. integrated trigger guard saves a roll pin step. takedown pin holes were tight to a standard pin set, slipped in with thumb pressure
good fit. cerakote was thicker than expected but worked out
Aero M4E1 Freedom Special Edition lower feels more expensive than the price. Patriotic engraving on the magwell is laser etched cleanly. Anodize is dark and even. Mate to a quality upper has zero rattle. Worth picking up if you find one in stock.
Aero Precision M4E1 Freedom Special Edition lower mates perfectly with my Aero upper. Zero detectable play at the takedown pin lugs. Patriotic engraving on the magwell is crisp. Anodize matches between receivers. Recommended Aero variant.
