My suggestion would be to go ahead and drill out the holes to 5/64, and then go bigger if you still have cycling issues. Like RamLake has already mentioned, the bigger you go with the ports the higher your chances are for fouling issues. Some guns will require bigger than 5/64 ports though, so just go up in small steps and you should be fine.

In my case yes, shortening the gas block is required. This is only becuase I like to shoot low velocity(1100-1140 fps) ammo through my gun. I have already done all the mods a person could possibly do except for moving the gas block in reguards to cylcing issues. Drilled all 4 gas ports to .101, reduced recoil spring, polished all moving parts, etc. At this point, I cycle successfully 80%-90% of the time with low velocity ammo. Just trying to get that 100% cycle rate. Just remember, every Saiga is different! I am glad you posted this info. I was wondering about turning down the

Tony, my plan was to find a piece of snug fitting copper tubing to go inside the barrel to weld against for the old gas ports. Is this similar to how you do them or do you recommend another technique?

I cut the barrel to approx. 15.5" and permenantly attached a muzzle brake which makes it a little over 18". I am VERY meticulous! It's almost scary......... Lol. I guess those parts consist of a shorter piston and gas tube?

Hey guys, I have searched all over this forum and cannot seem to find a detailed thread discussing moving the gas block rearward on the S12. I know that several companies out there move the gas block back 2-4 inches to help cycling ammo on shorter guns, but can't find a DIY thread. I have acces to a metal lathe for turning down the barrel so the gas block can slide farther to the rear, but have multiple other questions reguarding this mod. Do I have to replace gas tube or can I shorten the stock one? How do I address the bolt carrier being too long? How do I successfully weld old gas

Hello, I was just wondering if anyone in or near the Tulsa, OK area would be interested in letting me borrow/rent their Saiga 12 threading kit? I wiill pay for shipping to and from of course. I am ready to cut a few inches off of my barrel and re-thread for my newly acquired tromix Monster brake. I will need the die, die wrench, and alignment tool. Any help is greatly appreciated!

Evlblkwpnz, maybe I do not fully underdstand what you are saying, but when I was making adjustments to my S12 the shell velocity iin which I was shooting had everything to do with reliability. My saiga would not cycle anything under 1300 fps prior to the gas system mods. It currently cycles anything 1100+ fps no problem. Maybe we are saying the same things in different words though....... I was under the impression that the lower velocity loads did not allow enough gas to enter the block which subsequently caused FTEs. So i guess my main concern is that the muzzle might release too much

Gentlemen, I have just finished a full conversion on my S12 which includes: pistol grip, AR stock, tromix trigger group, recoil spring, gas port mods, ect., but now I am interested in adding a Tromix monster brake for the sole purpose of a little additional recoil reduction. I have spent numerous hours adjusting/modifying the gas system to successfully cycle 1100-1150 fps target/buckshot shells 100% of the time without FTEs with the stock 19" barrel. I would like to cut the barrel to 13" and add the Tromix 5.8" brake to keep me within the legal limit of 18" for a non sbs. Here are the quest
