I just ordered 3.
1 FDE with custom engraving
1 Black with custom engraving and NFA engraving
Dang cheap. $45 for an engraved lower, $31 for a standard lower.
Free shipping over $70
Code: Spring15 for 15% off entire order
Code: FB2015 for the $31 standard lower deal (choice of colors except clear/smoke)
Same technology as the ATI Hybrid (brass buffer tube threads)and the polymer makes the custom engraving almost look 3D.
