cerakoted FDE finish on this lower is well applied, no thin spots or runs. tolerances are tight against an aero upper. integrated trigger guard saves a build step. FDE shade is darker than magpul FDE, leans brown
Aero Precision M4E1 stripped lower in FDE cerakote has excellent fit and finish. Cerakote is consistent and durable. Mate to my Aero upper has zero play at the takedown pin lugs. FDE shade matches Magpul tan close enough.
Aero M4E1 stripped lower in FDE cerakote is a good base but the FDE shade on mine ran slightly darker than my Magpul FDE parts. Cerakote is consistent and durable. Mechanically standard mil spec.
Aero Precision M4E1 stripped lower in FDE cerakote works as expected. Cerakote is consistent. Mate to my Aero upper has zero play. The price is a touch steep for a stripped lower at this tier, but the cerakote shade is the differentiator.
