I am looking to SBR a 9mm SMG-style platform or possibly convert my AR-15 to an MCX-Spear 300BO "subgun" impersonator. I do not want another MP-5, though an MP-5k will show up at some point.
I was initially looking at the Beretta PMXs but, I also don't get the benefit of a career in Italy using a PM-12 so I question that option even though I can get one for ~$1,000. Then you have the B&T options, with even the GHM9 being pretty darn expensive. Sorry but, the CZ Scorpion just doesn't do anything for me. The Sig MPX might be a reasonable option but, I question the high cost and comparisons against the B&T options in a similar price range.
Then there is the MCX-Spear 300BO! I could run that one ~15 minutes after it hits my mailbox since I already have a tax stamp for its 'parent' and no NFA wait. Compared to the 9mm options, I think the smaller bearing surface of the 7.62mm bullet has merit along with the heavier payload.
Am I overthinking things? If you are not going to get an MP-5/SP-5 option, what SMG-themed pistol/SBR would you get for ~$2K? Would the additional size of the MCX Spear 300BO option rule it out of the SMG role? I am looking for something easy to transport discreetly that is effective out to 100y (or m) against someone, or their dogs, who intend to harm me or those I care about.
TIA, Sid
