Be careful the gun grabbers are watching us!
It is illegal to transform your rifle into a pistol without prior BATF approval.
Maybe not a good idea to let everyone know what you are doing.
I personally have no problem with it, but it was brought to my attention when I was speaking of doing the same thing.
Then I went home to read the warning label on the original box and it states that you may only use barrels with a length of 16" or greater on my reciever. My original purchace was the 209x50ML.
Just thought I' d mention it.
