Yes, a suppressor is legal to have and to hunt with here in PA. There is a bunch of paperwork, photos, fingerprints, background check and several months of waiting for the BATF to put a $200 stamp on your paperwork before you can take one home. The best money I ever spent was for my 77/22 with integral suppressor and this 30 cal can. They are worth every penny as far as I am concerned.
