Hey folks. Looking to pick this up just as a cool looking range toy, maybe even as a home defense scenario, but its really just a toy for under $500 all in plus an optic. Start with Hipoint Carbine and drop it into a High Tower MBS chassis. They just look badass! I just really am not sure if I want to keep it the same in 9mm as my pistols to keep ammo uniform or try something new like 10mm or 45ACP. Im sort of a novice in the caliber area and just buy things that are fun. Many have 9mm/22cal pistols and hand full of shot guns so far. Thoughts?
