Great Customer Service
When one elastic (rubber band) broke, i contacted Mould King directly and they told me to go through Amazon (where I bought it from, obviously) to save me shipping costs. I did and they gave me about ten elastics. Thank you, Mould King!!!!

Fun Build
This is a really fun build because when you're done you have a little rubber band toy. The instructions for building the model are really good and easy to follow. The bricks are well made with good colors and they stick together easily while also staying together unless you want to pull them apart. It's a fun model and at just 563 pieces this is an easy build that's also a lot of fun.

Doesn’t Shoot
Instructions were weird at one point, wrong about how to assemble it. Gun didn’t shoot so we took it apart and rebuilt is several times and it still didn’t work. Wouldn’t recommend.

Great but…..not lasting
This was easy putting together but unfortunately the mechanism that makes it shoot keeps having issues. My child has become so frustrated he doesn’t use it now. Now he has it displayed in his room but can’t use it.

More for display
Done of the rubber bands snapped. It jams every time you go to shoot, having to be taken apart/readjusted.

It could be better
I've been looking at this gun for a while, and finally decided that I would go ahead and buy it. I've had it for a few days now, and wanted to state some small issues that I had that could possibly be big issues for you. The instructions are great! Easy to follow and they specify what size rubber band to use in each step. But... if you've ever had a Lego set, you know that Lego numbers their bags so that it's easy to build (as for instance, steps 1-27 are bag 1, 28-43 are bag 2, etc.). But this set is not like that. I ended up opening 8 large bags of tiny pins and beams and quickly ran out of room on the table I was using to build. So just keep in mind that you WILL need a large space to build. As said above, instructions are great and once I got the no-room situation figured out, I was able to build. Just so you know, when making the shooting mechanism, it seemed as if they hired a pro knot-maker to make the knot that holds the string to the back of the gun. I ended using an old Lego builders trick where you put the string into the cut out of a pin, and pinch it with another technic piece to hold it in place. This is also better because you don't have to untie your knot, adjust the striker, and then tie the knot back. Just take off the piece pinching the string, adjust it, and put it back. Simple. Easy. Awesome. Here's an issue you can't really blame the company for since they don't make it, but the rubber bands are HORRIBLE!!! They snap under little pressure and the main band broke after six shots of the gun. I ordered some more rubber bands off of Amazon that are much more durable. They work way better (this is them: boolavard 200 pcs 1.5" 38mm) mind you, this is only for the shooting mechanism, not the trigger, or the mag lock. Besides all of this, I like this gun alot. The sight on top works great and is super accurate, and the the slide and mag are cool too. I like guns 🙂↕️🤌

Fun!
My 12 year old enjoyed it. It didn't really 'work' after assembly, but that could've been our fault, to be fair.

The instructions on how to build the firing mechanism are incomplete and not easy to understand/ follow, I ended up building the gun without the firing or loading mechanism working….

Beware instructions are not clear on crucial details. Youtube helped to figure out the firing mechanism only it was an older version? with instructions 77 and 78 reversed. Still very hard to figure out where exactly to loop the string through. It took us 8 hours to build with having to take apart / re-assemble the firing/loading mechanism many times, but we finally got it to shoot (without jamming or coming apart) Other problems are the magazine, not a sturdy build, hard to put together and prone to launch out all the bullets while trying to fill the magazine. (Also the elastic string broke, had a defect weak point, but we found an alternative) Loading a bullet in the chamber is very finicky, things are prone to come apart while pulling the slide back. I don't think it will have much longevity but it's still nice as a display model.

Gun is easy to put together, rubber bands and string not so much. Rubber band snapped and had to find a replacement. Also not very clear on where and how tight the string needed yo be. Won't buy another.

Very good quality Lego-compatible set. Works very well, impressed with the action.
