On my behalf a friend recently acquired a Sendra preban stripped AR15 lower. Not much information available on the Sendra hardware other than comments of the anodizing appearing to be purple. True to the comments mine started off purple. My friend who also happens to work in the industry and is an AR15 guy himself would not ship the Sendra as it sat. In a very generous gesture my friend decided to dress up the Sendra.
First off he had the stripped lower coated in GunKote matte black. He then installed a Geissele G2S Trigger, BAD ASS CASS, KNS Anti Rotation Pins, Magpul Enhanced Trigger Guard, Magpul MOE+ Grip, Milspec Buffer Tube, H Buffer, Noveske End Plate and a VLTOR IMOD.
This lowered turned out so well I have not yet decided what project to apply it to. Once I have the lower in hand I will post quality images.
