I just want to give my endorsement to Murray's for a fine job replacing the original firing pin in my SKS with a new stainless pin and spring. I'm very happy with the work and feel much safer loading up my SKS. Turns out the old pin was a rusty, crusty mess and it was probably just a matter of time before it slam-fired a 30 round clip on me. The shipping was dog gone quick too. I wasn't expecting it back so fast. Thanks.
