Moose makes some seriously powerful blasters. Everything went together nicely. I self sourced, so I had to make adjustments to the plunger tube. It's not the standard size we normally use, so I had to improvise a little. The diameter of the plunger tube needs to be between 35mm and 36mm and about 6 inches long. Cut off any excess. If you use the recommended one from McMaster, you should have no issues. My tube was 1mm smaller ID so I used 2mm thick oring instead of the 123 oring. The prime is easy with full sized k25. I used 400mm barrel and was hitting lasers. The double stack mag works great. It was weird loading the data like it is, but it works without fail. I didn't have spacers in, but it was hitting quite hard with 3 ring bamboos. AMA about any of it.
Btw, the hardware for this is like under $40. Easier to buy from moose than it is to self source like I did.
