Is the kel-tec plr-16 a legitimate defensive weapon (mainly for HD) or just a mediocre conversation piece? they seem to have no real use and the current price for one seems ridiculous. it would be okay with a vertical fore grip but that classifies it in AOW and you have to go through paperwork and tax stamp. the only thing I could think of is it would make a decent SBR platform. can anyone give any input if they are worth it?
