Questions people ask

How hard is the build? Comparable to a large Technic-style set. Clear printed manual and numbered bags; set aside an evening or two.

Is it LEGO? No. It is a compatible building-block kit that fits standard brick dimensions, so it sits next to your other sets.

Does the mechanism actually work? Yes — you cock it by hand, the magazine comes out and goes back in, and one button releases the soft round. It is a display model, so handle it like one.

Is it a gift? Often. Birthdays, Christmas, a reward for a job well done — or simply for yourself.
