rob0126 1 Posted October 18, 2011 Report Share Posted October 18, 2011 (edited) I just received my 'sporter' Saiga 7.62x39. Imported by TGI w/ 09 serial. Also has no step in the barrel. After looking over the rifle quite a bit, I noticed how the firing pin is setup, in relation to the hammer. My question is, is the firing pin free floating? Because it looks like it is, and was wondering how, when the hammer drops, that it hits the pin consistently, with no tension on it to stick out from the rear body of the bolt? I dont understand how the pin gets hit by the hammer, thus popping the primer on the cartridge. I do see how the bolt rotates as it comes up to connect and lock with the barrel. You can see how the pin slides a bit back and forth by turning the bolt upside down, and visa versa. Can someone shed some understanding on this mechanism for me? thanks Edited October 18, 2011 by rob0126 Quote Link to post Share on other sites

Can someone shed some understanding on this mechanism for me? thanks The firing pin is prevented from moving all the way forward by a live primer. This allows for enough rear length so that the hammer can tag the pin. Quote Link to post Share on other sites

This allows for enough rear length so that the hammer can tag the pin. Still puzzled. If I turn the bolt upside down, the firing pin will protrude out from the surface of the bolt face hole, and back in by turning it back up. The manual says the .223 versions have a spring, so Im guessing the rest of them dont. My concern is slam fires, like an SKS. How is this prevented on a Saiga? thanks Quote Link to post Share on other sites
Gunfanatic 221 Posted October 18, 2011 Report Share Posted October 18, 2011 You’re over thinking it. The firing pin does not have enough mass to set off the primer. Quote Link to post Share on other sites

So even pulling the bolt fully back, then letting it fly, to strip a cartridge, and engage, won't set a primer off? Edited October 18, 2011 by rob0126 Quote Link to post Share on other sites

rob0126 1 Posted October 19, 2011 Author Report Share Posted October 19, 2011 (edited) Here's my last question about it: How exactly does the hammer strike the firing pin, when the pin is not protruding out the rear of the bolt, seeing as the hammer then, will only hit the rear of the bolt face? thanks Edited October 19, 2011 by rob0126 Quote Link to post Share on other sites

No it didn't. Im asking how this mechanism works, so I better understand it. I dont like going blind into anything. I understand a spring loaded system, not a free floating one: I guess I need someone to lay it out for me technically. I just received my 'sporter' Saiga 7.62x39. Imported by TGI w/ 09 serial.

This allows for enough rear length so that the hammer can tag the pin. So does this mean it's a 2 piece firing pin? What Im trying to figure out is, what mechanism pushes the firing pin out the rear enough, for the hammer to contact it(while the bolt is engaged with the chamber and round), when the trigger is pulled? thanks Edited October 19, 2011 by rob0126 Quote Link to post Share on other sites

Hahahaha Yes post two says it. The firing pin rest directly on the primer. With about 3/16 of an inch hanging out the rear of the bolt. The hammer goes all hammer time slamma Jamma on that protrusion.

rob0126 1 Posted October 19, 2011 Author Report Share Posted October 19, 2011 (edited) Ok, so the cartridge has to be in the chamber, for the pin to protrude out the back of the rear of the bolt face, while it's engaged with the chamber, right? I didnt want to put a cartridge in the chamber for safety reasons, being inside the house. I noticed the manual says dont dry fire the gun. But considering the firing pin doesn't protrude out the back, with no shell in the chamber, I would guess it's only harming the rear bolt face, no?

hutchsaiga 93 Posted October 23, 2011 Report Share Posted October 23, 2011 Well possibly.but If you have the rifle tilted back the then gravity will pull the firing pin rearward and the hammer will contact the pin and slam it forward in the channel smacking the tapered section of the pin into the hole in the bolt face. But damage from this is unlikely. Quote Link to post Share on other sites
G O B 3,516 Posted October 23, 2011 Report Share Posted October 23, 2011 Excessive dry firing will damage the end of the bolt. Like a couple hundred times in a row. The firing pin of the one piece type has a mass small enough that it cannot set off the primer unless struck by the hammer. The pin is also too short to touch the primer and protrude at the back of the bolt until the bolt is fully locked. Quote Link to post Share on other sites
