Why have your gun built or modified with us?

  • Fixed price for work

    As a guide, we estimate the price for the work to be between 2500 - 6500 CZK. We try to adapt to everyone's price budget. You will receive a price quote from us and, unlike our competitors, it does not change. And if we spend a whole day or three on the weapon due to unexpected problems, that's up to us :)

  • We build it as if it were our own

    We build guns because we enjoy it and we want others to have the joy of a well-tuned build. The same gun from the same brand will always differ in even the smallest details (even if only by hundredths of a millimeter), which is why each build is unique to us, with its own specifics and we approach everything very individually.

  • You have a guarantee with us.

    The process is long and there are countless details. Even though we have built countless querries over the years, we may miss something or the ravages of time may show. However, we believe in our work and if a problem arises, we will be happy to solve it free of charge under the warranty.

So, do you want to have your gun fine tuned by us? :) Write quickly what you are interested in and we will get back to you soon.
