its pretty good

the screws were a little karge but over all a pretty good blaster

Amazing, Needs better screws

I love the blaster but definitely think it needs threaded inserts. I have taken apart the gun 5-6 times and the screws have begun to strip the plastic. For a hobbyist blaster, it would be nice to see a better design with the idea of the customer in mind.

Great blaster, bad screws

The Jupiter once assembled is an amazing product, 10/10 I would recommend everyone that attends nerf wars of any type have a jupiter+proton pack.

The build guide is great, 10/10 clear and easy to follow.

The screws provided in the kit really stink. 0/10 They fit way too tight most of the time and they are extremely easy to strip out. I ended up exclusively using screws leftover from old nerf projects to avoid having poorly fitting stripped screws throughout my blaster.

Just difficult

It took a very long time to get here and when it came it didn't have instructions so I watched a confusing youtube video and asked a question answered a about a month from then and then realised the screws where to short. I don't even now what other parts I'm missing cause I only made it to step 4!

Amazing Little Blaster

Easy to assemble, great video guide to go along with it. Definitely want to get another with a proton pack!
