These guys are a small company out in the states who do specialised 3D printed parts for quite a few GBBRs. I ordered 4 feed lips and 2 base plates for my vector mags and they arrived within the week with a hand written note saying that he had included a few extras, I now have 6 feed lips and 4 base plates along with some slightly strange American sweets. The parts work and I actually prefer the printed base plate to the original. Overall 10/10 absolutely perfect
