I thought that I should get a review out because I had problems that no one had mentioned with this kit. After installing, I found that the metal dart gate and pusher were set far too high for both stock nexus 12 round mag and the worker 18 round mag. Dart feeding would consistently rub a lot on the next dart under the one being loaded, causing for very easy jams. In addition, I would not recommend this product as I did not notice and significant increase in accuracy either, rather I just faces several issues that I tried to fix myself. I know others may not have had the same issues, however I feel that it is worth mentioning. I would love to return it but my stubborn self instead resorted to drilling and sanding the metal to try and fix my loading issue and ended up making no progress. The nexus pro with a spacer and some plumber's tape to airtight the original blaster was great as is and should have been left that way. Who knows. , maybe it was user error but ill leave that up to your own research and discretion. I do want to recognize that this website seems very well put together as well as many of its other products, and that I have no really negative review towards Out of Darts.
