Some serious work were done in these custom Tippmann M4A1 HPA Blowbacks by the Powair6 in France. If you've got some cash to spare for these premium custom work, then prepare to shell out €1,070.00 for the DMR version. If that's too much for you, then you can settle for the more affordable €999.00 Tippmann MK5 Custom Blowback HPA.
