    Great kit, went together easily with the assembly instructions. Took a little while to ship it to me but I am in Canada so I expected that.

  2. Dylan Crider (verified owner)

    One thing I can note on the C4 kit is both kits I purchased seemed to have the holes slightly offset from where my prints were, I checked my prints dimensions and they seemed correct but the holes just barely lined up between the print and metal peices. Didn’t make it unusable though, and FLF has since fixed the issue.

    You guys really went above and beyond to get it to me too.
    Kit performs great! It’s nice and over-complete,
    Extremely happy with the cnc’ed plunger and trigger, they’re properly finished too, no sharp edges or nothing.
    Would definitely buy from you guys again.

    The kit was of good quality. I would have appreciated a build guide video as my kit didn’t go together as well as my previous purchase

    Frankly, I’ve ordered kits from a few different companies, and yours was the most smooth, no nonsense experience. When I reached out for questions on the engineering, you were able to answer intelligently. I’ve since reached out directly to Slug with some feedback and questions, and will be designing some blasters based on his designs. My experience with your company is reflective of how I want to treat my customers, so when the time comes for someone to make my kits, I’ll most likely be reaching out to you.

    The kit works exactly like it should and I have had no issues with functionality.

    The Caliburn 4 hardware kit worked great with my build. Would highly recommend for those who are looking to build their own caliburn. All the parts fit together great, with several spare pieces.
    Build video on YouTube was very helpful for reference during assembly.
