Hey I was looking at the parts for the Suomi M31 and saw that there where 2 bolts for sale "BREECH BOLT, USED (W/ STRIKER & PIN BOLT)" Product #: 490060 and "BOLT ASSEMBLY, USED" Product #: 1598640. For the "BREECH BOLT, USED (W/ STRIKER & PIN BOLT)" Product #: 490060 I was wondering if it is a modified bolt similar to the tnw semi auto mod to make it a semi auto striker fired? Also what are the differences between the bolts?
Item #1598640 and #490060 are both full auto bolts. #1598640 is an assembly with striker, pin bolt, and extractor. #490060 just has the striker and pin bolt.
