Theres a bunch of videos on the JP. Theres like 2 vids on the MBX and theyre both by Adrian Cobb, MBX owner. I did an unboxing, tabletop, and shooting review. I put 500 rounds, only 1 failure to feed and it wasnt the rifles fault. I was testing its reliability with my problem glock mags and it did pretty good!
Ill be posting the vid soon. It definitely can run faster than my finger can. Im no pro but I felt like it when shooting this thing. I hate optics because red dots like to play hide and seek with me. I ran bill drill a few times with it. Not only did that dot just nod calmly at me, i was able to push the splits to what a c class shooter shouldnt be seeing.
All in all, it works. Its a handsome rifle, and its cheaper than the jp.
