This is the first time I have bought an unassembled kit, and wow, what an amazing first time build. The kit is exceptionally well thought out (such as the inbuilt hex slots for turning the nuts) and the much smaller size while still retaining significant power. It feels great to hold, to reload and it just looks great. It is very beginner friendly, and I can already unassemble and reassemble the blaster with confidence and without watching the assembly video again.
If you are a first time builder and want to get into building, I can see no greater option than this. Some notes however! Make sure you check you have all the parts (refer to the assembly video, there is a section where it has all the parts laid on the table) as it turns out I was missing a few. Out Of Darts promptly sent me the missing parts free of charge and with good communication. Also make sure you have the tools listed in the assembly video (especially the drill and drill bits), as I did have to widen some of the holes. If you are having trouble with the prime being a bit stiff, be sure to check your airseals, as I initially thought I had built it wrong but it turns out I had the airseal way too tight. I loosened the airseal and used a fair bit of lube on the o-rings and now it's great.
Highly recommend!
