Greeny ... most any of the replacement firing pin assy's you'll find thru Midway, Brownell's, etc. will be fine ... Callahan, Tubb, Gre-Tan, etc... I think Callahan's "run of the mill" replacement is only like $40-$45, and is well worth it ...

I've never tried one of the "speed lock" versions, which are supposed to have an even faster lock time, but Remington's rifles already have one of, if not the fastest lock time, so it's really no sweat to stay with a 'standard' model ...

either way, get rid of the cock-block assy, as it's nothing but a mess - so much of a mess, Remmy doesn't even make them anymore ...
