Ronin38 2,117 Posted January 29, 2012 Report Share Posted January 29, 2012 Just bought mine today from Tom @ Cadiz. He said it's a 2011 with 4 ports. I don't know what size they are. I'm going to check them now to make sure they're clear! Quote Link to post Share on other sites
G O B 3,516 Posted January 31, 2012 Report Share Posted January 31, 2012 (edited) 2001 model, long barrel, full integral choke. 3 ports at .078. Runs anything i have fed it. Edit to add: the mfg date and barrel length should be posted here for comparison. Edited January 31, 2012 by G O B Quote Link to post Share on other sites
macaholic 5 Posted February 4, 2012 Report Share Posted February 4, 2012 I have three Saiga-12's. My 2008 model has a 2011 16" four port barrel that started out at .063 but I opened them up to .076. I also have a 2009 S-12 with a 19" three port barrel that I believe to be .080, because I can fit a 5/64 bit with some play in between. Lastly, My newest S-12 is a 2011 19" with four ports at .063.

macaholic 5 Posted February 4, 2012 Report Share Posted February 4, 2012 (edited) Guys I have a Factory 4 port(Diamond Pattern, no clue what size) unconverted Saiga-12 that cycles cheap bulk ammo absolutely perfectly on gas setting 1. No jams or stovepipes or FTF ever. Bought it from a friend for $400. Is this normal??? I've read several posts on factory S-12's that will run bird shot on the #1 setting. So I would conclude that it depends on the size gas ports the gun came with when it left the factory. From what I've gathered, the factory doesn't seem to follow any guide lines on the size port holes they install in these guns. It's possible that you have one of the guns with four holes at .076 and/or the gun is simply well broken in. Edited February 4, 2012 by macaholic Quote Link to post Share on other sites
vicdoc 38 Posted February 4, 2012 Report Share Posted February 4, 2012 I thought there were 3 ports, because that's all I could see, but in looking closely and using a paper clip, there are actually 4, the one closest to the muzzle is partly covered by the block. They are small, maybe about 2 mm. I just got this yesterday and don't know how it works. Quote Link to post Share on other sites
arlan in arizona 1 Posted February 5, 2012 Report Share Posted February 5, 2012 I have two S-12's. One is a 3 port the other is a 4 port. I just today stated converting the 3 port so I thought I might as well take it down a little further and check the size. All three of the ports are .0795. All were exposed. Will check the 4 port gun sometime down the road. Both guns run well with no FTE so far. Quote Link to post Share on other sites

The other two are four ports and they both needed to be fiddle fu%ked. Edited February 5, 2012 by macaholic Quote Link to post Share on other sites

They are small, maybe about 2 mm. I just got this yesterday and don't know how it works. Fourth hole partially obscured by the gas block? Sounds familiar. As a matter of fact, I've been down that road twice already. Take the gun out and see if it runs. If it does good. If not, well that's where all the fun begins. If your gun is a 2011 four port gun, the gas ports should be about .063 or one 16th of an inch. The gun will run with these gas ports, but I had to open up the gas block hole with a slightly larger drill bit to expose the one gas port on both of my four port barrels. You can also use a rat-tail file to perform this operation as well. Also, you may want to check the gas ports for crud because I found some in two of my ports on one of my four port guns. It's not a real hard fix, it's simply knowing what to do to make it right. Edited February 5, 2012 by macaholic Quote Link to post Share on other sites

siminov 164 Posted February 5, 2012 Report Share Posted February 5, 2012 I have a 2011 with four ports, the ports measured .063 of an inch. I have the same. One hole is partially covered. It shoots buck and slug fine. I don't use it for birdshot and only tried a few rounds through it on setting 2, it worked. Quote Link to post Share on other sites
arlan in arizona 1 Posted February 5, 2012 Report Share Posted February 5, 2012 I just check my four port s12. All four ports are .063. As I mention earlier my three port gun has .0795 ports. The total size of the ports for comparison are 4 ports times .063=0.252 3 ports times .079=0.237 Quote Link to post Share on other sites
