S&W M76 & MK 760 TECH
While measuring 76/760 bolts I have come to find out that the dimensions on S&W 76 bolts are not the same as MK 760 bolts. The bolt face on S&W bolts is further forward. This means that the S&W bolts do not use the same extractor as the MK Arms bolts. All the bolts measured so far have the straight transition.
If anyone has an MK760 bolt with the radiused transition I need to measure it to see if there is two different versions of extractors for the MK 760s.
