OK. First off let me say thank you for any information I receive from this thread. Now to business. My wife owns a PLR 16. Neat little pistol. The problem is that when shooting, it becomes REAL easy to get your hand close to the working end of the muzzle. I know that if one puts a vertical fore grip on the PLR it becomes an AOW. My question is, if one puts the new Mag Pul HFG (Horizontal Fore Grip) on a PLR, does it become an AOW? Now the next question, What would the process be to make sure the PLR would be legal if I purchased the "AR stock/pistol grip" kit from Kel Tec and wanted to create a light weight SBR? Thank you!
