We are unable to at the moment endorse anodized lowers or frames, but For added info on anodized lowers or frames be sure to email us at [email guarded]. I’ve engraved BRN-four 416 lowers to mimic the HK 416 logos. With ample passes, a fiber laser can perform deep engraving https://ghostgunsofficial.com/product/ghost-gunner-3-s/
