I had a lot of fun building it. Although looking for pieces has a bit annoying at the beginning as the bags aren’t organized but building steps, it gets more fun once you realize the bags are organized but pieces types. For instance, all the length 3 pieces will be in the same bag that contains all of the one type of specific recurrent piece and then all of another type of recurrent pieces, etc. I was surprised of how much power it has, so much that hitting a solid surface will disassemble the bullet once it absorbs all the energy. I would suggest superglueing each individual piece of the bullet. The elastic bit was easy enough to understand from the video and they seem strong enough to last quite a bit. He does give is two extra set of elastics tho. I hoped it came with the scope he shows in some of his videos. Overall, lots of fun.

Great product, especially great design and ingenuity. Thank you for transparency on your work and for fast shipping. One of the bands didn't last long, but otherwise it's exactly as described and shown in videos!

List of lego little confusing but manageable. One important thing is missing in manual. Where to put rubber for loading a gun. The long one . I found it on videos.

Although the outlook is pretty decent, the semi-auto shooting performance is not as smooth as in your video. I have checked the tutorial several times, and I think the issue is that the rubber bands are not very effective during shooting. Even after making several adjustments, it still doesn’t work as a semi-auto pistol.

This thing looks amazing and the mechanism works way better than expected. The only caveat to this is that I found it to be rather fragile. Some super glue is recommended in the instructions, but I had to use a lot more just to keep it from falling apart from slight movements or using the bolt. Other than that, it is an amazing display piece and, with careful handling, really fun to try and shoot targets with. Genuinely impressive work of Lego engineering
