http://riflestocks.com/store/page18.html http://www.aceltdusa.com/documents/AR-UL_Assembly_Instructions.pdf I have had a Form 1 in the works for a while and i really just want to go out and shoot even if its as a pistol for now. I came across this stock looking for a buffer tube just to use as a pistol. So heres a few questions 1. If i can get it minus the spring and buffer will i be able to use a carbine buffer and spring i already have or does it use a specific spring & buffer. 2. My plan is to just use the buffer tube and the soft foam overtube until i get my form 1 back and can attach the actual Butt & pad. is that possible. Is there a cap i can put on the back to make it legal to not accept the butt & pad and just give them to a friend to hold for me so i don't have possession of them? 3. What all comes with this from ace? Do i need to purchase anything else? Thanks for the help im tryin to do this so i can use it as a pistol then also have a functioning stock as well when i get the form 1.
