| Can you remove the firing pin spring on the SLR107 and use the rifle normally? |

Quoted:
I haven't seen a need to on my SLR107UR. Works fine with it. I just don't understand the need for it. I know people will say it's for soft primers, but I haven't heard of anyone that's using an inertia firing pin having problems. My issue is that it's a 10 cent part that could fail and really make for a bad day. So why have it? I figured somebody else had already felt this way and removed it. |

From my understanding, the SLR has a mushroom-shaped end on the firing pin, which is supposed to prevent debris from entering the channel. I don't know if this helps of not.
I have heard of the firing pin spring breaking and causing full-auto or getting bent and preventing the pin from moving, but this seems uncommon. Just wondering if anyone had removed the spring and used their gun. The Russians seem to be happy, so I can't figure out why the Bulgarians changed things. |

I'm not sure if military Bulgarian rifles even have a spring loaded firing pin. It seems like it's a feature on the stamped, export rifles. Bulgaria has moved away from stamped in favor of milled rifles, possibly due to Russia giving them crap for "stealing" the design. |

Weather the Bulgarian military rifles have a spring loaded firing pin or not, I'm not sure. I do know that the bolt and firing pin design that we see here with the SLRs, is the older AK/AKM design. The free floating firing pins and more slender stem on the bolt came about with the AK-74, and the Russians continued with that design with the AK-100 series. |
I pulled the firing pin for an 7.62 SLR rifle. Here is a pic comparing to a flat Romanian (top) , fluted East German? (middle) and Bulgarian spring loaded FP (bottom)
They are all the same length. All the bolts fit the Bulgarian bolt but I think in an emergency the EG bolt fits better as it has a round end and is not flat and thin like the Romanian FP. I would be worried about slamfires using the Bulgarian FP without the spring as it has more mass than the other FPs. |

For some reason, I was imagining a completely different spring setup. Still, it seems the Bulgarians were trying to solve a non-existent problem, especially in 7.62. Also, this seems to create a logistical nightmare. |
