[ARCHIVED THREAD] - Problem with SAR-2 extracting

Posted: 5/10/2004 10:31:23 AM EDT

My SAR-2 left an empty in the chamber and the extractor slipped over the rim. I had to knock it out with a cleaning rod. I replaced the extractor spring and slightly shortened the hole in the extractor to increase extractor tension. While my quick rapid rife followed by letting a round set in a hot chamber for a couple of minuites followed by another rapid fire mag shows the problem did not reoccur, I am wondering:

The chamber has some rings in it, it is not baby-ass smooth like my Inrange Bulgy or my other SAR-2, should and how should I polish the chamber to help things a bit and should I even polish it at all?

felt bob and a dremel using and in and out motion.

use very fine cutting paste.

a bud had a friend with a pos oly m4 with a chamber cut with a dull reamer...lots of rings and failures to extract as the result. and hour later, it looked as good as gold.
