Navgunner Posted April 24 Report Share Posted April 24 Would a few MK760 owners please measure the outside diameter of their bolts and the inner diameter diameter of their receiver tubes? If multiple people could respond, even better. Thank you! Quote Link to comment Share on other sites More sharing options...

I’m trying to get as many data points as possible to see if there’s variances. Quote Link to comment Share on other sites More sharing options...

MPFiveO Posted April 28 Report Share Posted April 28 Was finally able to get mine out of the safe today. From my Fruithurst, AL MK 760 Bolt 1.125 dia Receiver 1.149 land Receiver 1.175 groove From my Panama City, FL 76A1 Bolt 1.115 dia Receiver 1.150 land Receiver 1.172 groove Measurements were taken several times with my Brown & Sharpe calipers so they're pretty accurate. It just occurred to me that I've never tried swapping parts between the two guns. Might be interesting to see if the bolts will function in the other gun. 1 Quote Link to comment Share on other sites More sharing options...

MarsOrBust Posted May 2 Report Share Posted May 2 I'm coming up with 1.126 on what looks to be a fairly low mileage factory Smith and Wesson bolt. Also wanted to say thanks for everything else you've produced for the 76, I think I have them all! Quote Link to comment Share on other sites More sharing options...
