Posted 20 Apr 2018 If you have a M37 you know what this is. Main spring rod unique to the m37 only. These do wear out and are extremely hard to find I had a M37 premay and sold a few years back just found this in the parts drawer. This one is NOS stock and unused $125 plus shipping John Ciszek 07SOT +1.510.406.4193 jecayc@hotmail.com Columbus, Ohio, United States Share this post Link to post Share on other sites
