Multiple magazines, including those from 300 Blackout Sim CGS Lancer, TM MWS, and GMP, experienced failures. However, performance improved significantly with .4g BBs and the original magazine, showcasing the rifle's strong kick and loud sound. He concludes the initial issues were likely due to the .25g BBs, whilst being positive about the rifle's look and performance with the correct ammunition.
