1960's made Belgian Auto 5 NFA Form 1, 5+1, with the friction ring in the rear position it runs everything, even low recoil Federal flite control....never a single malfunction since the barrel was shortened. 12.5" LOP, 14" BBL XS Tritium front, and before anybody gets on me about defiling a real Belgian Auto5, it was a sub $300 pawnshop pick up with no finish at all, practically in the white and pitted, with a cracked stock almost in splinters. And yes that is a copy of the Form 1 taped to the stock.
