garandman 11 Posted September 15, 2012 Report Share Posted September 15, 2012 Getting ready to SBS my Siaga 20, but since there's more Saiga 12's out there figgered I'd ask here... MY 20 runs flawlessly (19" bbl) . But cutting the barrel down to 12" will necessitate opening up the gas ports. So here's my questions - Do the larger ports gunk up the gas system faster? Also, do you know what size / how many gas ports ya got? My vodka special has 4 ports. Any help appreciated. Thx. Quote Link to post Share on other sites
sunnybean 939 Posted September 15, 2012 Report Share Posted September 15, 2012 Yes, bigger holes mean more fouling. The S20 is a different beast than the S12. I know you can cut a S12 down to 12.5" without moving the gasblock. I doubt you can go that short on a 20 without redoing the entire gas system. Best to send it to Tony.

But already planned to send it to Cadiz. I'm 90% sure I could do it myself, but that 10% is a nagging doubt. Best let the experts handle it. Quote Link to post Share on other sites
TonyRumore 1,332 Posted September 15, 2012 Report Share Posted September 15, 2012 I have never done an SBS without shortening the gas system. I am not sure if you can get a 12.5" 20ga to run low base with the standard gas system......and not have crazy ass huge gas ports. In my limited experience with the 20ga SBS, I actually moved the gas block clear back (3.81") to the 8" bbl position, when coupled with a 12" barrel. Tony Quote Link to post Share on other sites

I do intend to shorten the gas system - its seems essentail to do so. The standard length gas system has about (I'm guessing) 8-10" of barrel beyond the ports. Shortening a bbl to 12" would seemingly require shortening the gas system, as I don't want one whomping big gas port. Sometimes it costs more to do it right. But then, its done right.
