My first experience with a KelTec pistol was also the first firearm I immediately traded in on something better. That said, KelTec acquired Magnum Research. My wife had a special build similar to a Ruger 10/22 in 17M2 with a fine picatinny rail integral to the receiver and carbon fiber tension barrel. 17M2 was getting hard to find and KelTec didn't want to continue that caliber. At their expense, I sent the rifle to their facility and they converted it to the 22LR carbon fiber tension barrel and correct weight bolt assembly for 22LR vs 17M2. It was even wrapped in a good quality shipping case on return. Ruger level customer service.
The lower image matches our rifles including the one converted to 22LR. Mine was already 22LR.
