offmarksman 0 Posted November 29, 2016 Report Share Posted November 29, 2016 My front trunnion is cracked. Got it secondhand with ar15 magwell already installed. Where do I get a replacement trunnion, what style/size do I need? What is required to change this out? I am new to the ak game. Thanks in advance. Quote Link to post Share on other sites
G O B 3,516 Posted November 29, 2016 Report Share Posted November 29, 2016 Where is it cracked? It may be easier to repair yours, if the crack is not in a critical area. Quote Link to post Share on other sites
offmarksman 0 Posted November 30, 2016 Author Report Share Posted November 30, 2016 Cracked up near the front, in the corner. I think it will just break again. Quote Link to post Share on other sites
essohbe 47 Posted December 5, 2016 Report Share Posted December 5, 2016 (edited) Can you weld it? If someone put the mag adapter thing on then they have ground away a portion of the trunnion and they probably fuck'd it up or bubba'd it. To get it out and put a new one in you have to get the rivets out, barrel pin, and take the shit apart out of the receiver. If you are new to this then don't even attempt it. If you have the tools and know-how go for it. Edited December 5, 2016 by ESSOHBE 1 Quote Link to post Share on other sites
G O B 3,516 Posted December 5, 2016 Report Share Posted December 5, 2016 If it is cracked at a rivet hole because of over tempering, then it is fixable. If the crack is even NEAR the chamber or locking lugs, then it should be discarded. 1 Quote Link to post Share on other sites
offmarksman 0 Posted December 6, 2016 Author Report Share Posted December 6, 2016 Does anyone know where I can source a replacement trunnion and what one fits? Quote Link to post Share on other sites
saltydecimator 482 Posted December 6, 2016 Report Share Posted December 6, 2016 russia. off a new gun. there are not really any spare parts.... sorrry champ an ak74 from some other countries gun may fit, but would be some trial and error.... and $ 1 Quote Link to post Share on other sites
Spacehog 2,218 Posted December 6, 2016 Report Share Posted December 6, 2016 (edited) Would a Bulgarian trunnion from an AK74 parts kit not fit? It would seem nearly everything else from a Bulgarian parts kit is compatible with the Saigas. Don't know about the barrel size and head spacing though.

essohbe 47 Posted December 16, 2016 Report Share Posted December 16, 2016 I was just thinking the same thing about a Bulgarian one. Quote Link to post Share on other sites

Vance665 225 Posted January 9, 2017 Report Share Posted January 9, 2017 http://forum.saiga-12.com/index.php?/topic/55393-cracked-front-trunnion-after-ar-mag-mod/ This thread has alot of good info. It appears a Bulgarian AK74 is a direct replacement but you might have an issue with the serial number. Quote Link to post Share on other sites
