Hey guys,
Getting the budget put together to build my pig gun. My question is are all lower receivers created equal? Is it best to stick with a BM lower to mate properly to the BM upper? I'm in the Air Force and our training rifles always have a ton of jiggle between receivers and i want to minimize that. Plus some cost savings will help when I present my proposal to the board(you know who i speak of).
Thanks
Mr. Wibble
