Dont leave us on tender hooks! '-)
Did you take the bolts completely apart and clean out the extractor spring and the tiny "extractor spring seat" under it? Caution!!! It's SOOOOO small and easy to lose!! But Brownell's has em for $6.99. 8-)
I've had 3 552's since 1971. None had any issues. First one bought brand new in '71 and the other 2 i bought
used. Various conditions of accumalated crud in the actions, trigger plates and barrels. Reliable nonetheless.
Let us know Rex. Thanks, Nick
