Frank Iannamico Posted September 18, 2022 Report Share Posted September 18, 2022 I have tried shortening Keystone's titanium firing pins to function as inertia firing pins to stop breakage HOWEVER, at least once a mag in full-auto I get a light primer hit. Perhaps the titanium pins are too light to reliably function as an inertia system pins? Has anyone had 100% success converting a titanium firing pin to the inertial system described here: http://www.machinegunboards.com/forums/index.php?showtopic=8854 Link to comment Share on other sites More sharing options...
buckeye10216 Posted September 18, 2022 Report Share Posted September 18, 2022 (edited) I have Frank, however, I do not have any secret sauce. Mine still barely sticks out when at rest, so perhaps I did not take off as much as some might? I did replace all the springs and tweak some of them. The Reising is a fickle beast to say the least! haha Edited September 18, 2022 by buckeye10216 Link to comment Share on other sites More sharing options...
jim c 351 Posted September 18, 2022 Report Share Posted September 18, 2022 Frank,After breaking a firing pin in both my model 50 and 60, I shortened 2 regular firing pins so they were flush with the end of the bolt.Then I heated the front 1/2 inch of the firings pin to cherry red and quenched it in 30 weight engine oil. Next I polished the end of the pin and heated the end to a light blue , no quench. When installed in the guns, both gave frequent failures to fire. So I bought 2 Wolf springs, which were too strong, both for me to operate, and the gun to function, so I shortened both until satisfactory. So far both are holding up.That's my story.Best of luck.Jim Link to comment Share on other sites More sharing options...
jim c 351 Posted September 18, 2022 Report Share Posted September 18, 2022 Buckeye.The firing pin that broke in my M60 just barely protruded past the face of the bolt, but it broke anyway.Hopefully you are luckier than I.Jim C Link to comment Share on other sites More sharing options...
buckeye10216 Posted September 19, 2022 Report Share Posted September 19, 2022 Jim C. Good to know. Over 3,000 rounds and no breakages, so don't jinx me! haha. I did have the ejector break already though. Link to comment Share on other sites More sharing options...

Perhaps the titanium pins are too light to reliably function as an inertia system pins?as anyone had 100% success converting a titanium firing pin to the inertial system described here: Firing pin UPDATE... Well I installed a unaltered full-length titanium firing pin. But still had an occasional light firing pin hit stoppage on full-auto. Upon the stoppage I removed the stock and checked. The round was chambered, the bolt was fully closed and the hammer was against the bolt. Extracted the round and found a light firing pin hit. All the other rounds that fired had deep primer fp hits. I have replaced the springs, action bar, bolt and hammer still have the same intermittent problem. If I rechamber the same round it fires. The gun functions okay on semi-auto. Anyone have a similar experience? Link to comment Share on other sites More sharing options...
StrangeRanger Posted September 22, 2022 Report Share Posted September 22, 2022 (edited) The Wolff FP spring eliminated all my light strike issues Maybe there's an issue with the connector not giving you a clean release in FA and the hammer drags on the sear?

UPDATE...The last time I had my Reising out was a few years ago at Tracie's TSMG shoot, and I was shooting it suppressed, which as you know gets everything behind the suppressor DIRTY, well I confess that when I came home I put the gun away without cleaning it.SO, I gave it a good cleaning and now it functions flawlessly.

fartsalot Posted September 29, 2022 Report Share Posted September 29, 2022 Suppressed Reising article http://archive.smallarmsreview.com/display.article.cfm?idarticles=4066Thank you for that article because it listed the year of Mfg by SN and now I know when mine was made and I found a source for a compensator replacement.

Glad it was useful, If you do a search there are a lot of old Reising articles there.Funny story about that year of manufacture list. I tried for years to get that from ATF via contacts and the FOIA, no luck citing it was tax information. Then a Reising owner, who was a Michigan police officer, told me he had the list. He said he called ATF and they Faxed it to him. Link to comment Share on other sites More sharing options...

Ryo Posted October 1, 2022 Report Share Posted October 1, 2022 I have a 3 digit Reising.. And I had to file the channel to have the firing pin go back a bit further so the hammer could contact it. Link to comment Share on other sites More sharing options...
