I recent purchased an Encore frame w/ a Pro Hunter stock and a forearm. (They had some unbelievable prices on frames!!!) I asked the person at the store - the sportsman place that has a warehouse - anyway - I specifically asked some of the questions that were brought up on this thread. I.E. - buy a pistol, can make it a rifle - OK?, but buy a rifle frame, make it into a pistol - Not OK? Initially, as per the letter of the law, technically, you can't change the one purchased w/ rifle stock to a pistol. As a result - I was waffling between the pistol or rifle version.
I decided on the PH setup, due to me not caring to shoot a pistol version of a rifle caliber. Upon his return from the rear w/ the box, he stated that they had an email out, reference the very question that I had asked. As per TC,
ALL FRAMES leaving the factory, are classified as
pistol frames. Pertaining to the fed form (4473?), the only information that was recorded, was the Ser #, the word "Receiver" and N/A in the last three boxes (29, 30, 31?).
It's been a few days, so I may not have quoted it verbatim, but someone might be able to look into it further. Also - if anyone is in AK, this place has some killer deals on pistol and rifle frame packages!!!
Hope this helps, reference purchasing a frame. Now - pertaining to the older ones - who knows!?!?!
Maybe someone should consult the Ouiji board or the Magic * Ball.
