This barrel material comes in handy for more than what it was intended. I have used this stuff in multiple different builds. FYI it fits perfectly in the end of an Aeon pro / nexus pro with no modification to either the blaster or barrel material. It is also great at shrouding DIY brass barrels for added protection and a cleaner look for mods. Use a section to shroud the brass barrel on my DIY mag fed “ProKrono” 280+FPS. Almost all the parts and supplies needed for this build can be found in this one stop shop. Out of darts should be your first stop when you need parts to complete the build your working on. Price is right and shipping is fast.
