Kel-Tec PRM 30 SMG Prototype
Kel-Tec has recently produced a developmental prototype based off of the PRM 30 pistol. They claim that this new fully auto pistol can feed 30 rounds of rimmed 22 WMR 100% reliably.
It features a conical flash hider and the ability to hold 3 magazines in the stock. This is a very nice feature giving you the ability to carry 90 rounds plus the 30 in the gun. The PRM 30 SMG prototype would need a 16″ barrel and be produced in semi auto to go on sale to a decent sized market.
In my opinion the conical flash hider looks a bit wimpy and attachment area that holds the stock onto the pistol could use some beefing up.
The PMR-30 SMG is a full-auto only developmental prototype. It is not available for purchase, and was specifically created to prove that 30 rounds of rimmed 22 WMR can feed 100% reliably.
