Please help a newb in reference to my factory gas settings - pic attac


Recommended Posts

Just picked up my new DDI 12 and I have zero clue how the adjustable gas system works. This one comes with a 4 position adjustable gas system which is apparently identified by little circles that get slightly larger in size. How do I know which setting im currently on? Is it whatever setting is to the top right of the plunger, so in this case setting 2?

Also.........if i push in the plunger and turn the cap counter clockwise, it fully unscrews out of the gun. If when it is fully screwed in, I push in the plunger and turn it clock wise, it goes to the next setting and makes a click sound as the plunger pops out to lock it in place.........is that basically how this works as far as adjusting it?

Did you RTFM?

 

On a Saiga, the detent plunger is your index mark. So if #1 is next to the plunger, you're on setting #1, which is the least amount of gas, appropriate for 3" magnums and high-brass 2.75".

 

But that may or may not apply here.

 

My guess would be that the largest circle indicates the most gas. Unscrew the gas plug completely, and find the biggest notch or hole in the back. Orient the plug with that largest notch or hole facing downward, and see where the big circle on the front lines up. It will probably be in the 8:00 position, matching the detent plunger.

Wow, good question.  There is nothing in the owners manual?  Unscrew the plug completely until it falls out.  Then easily turn counter clock wise until you feel the "Higg Bee Cut" when the threads engage.  A gentle click and feel.  Then slowly tighten up while counting the number of turns it takes to do so. Run it up with finger strength.

 

Is there included with the shotgun a gas regulator nut wrench?  If not use your fingers.  Might be tight.

 

Continue tightening until it gently stops.  Then shoot.  THEN start loosening?  My dumb guess is the tiny dots that get bigger line up with the barrel.  Guess only.  But ... it might take more than just one complete turn to let gas in from the barrel.  About the only way you can be sure is to run the regulator all the way up finger tight. 

 

Then shoot the shotgun and see what happens.  If it does not cycle, start unscrewing the regulator one dot at a time.  Open up the gas. Keep unscrewing until the gun cycles using 3 dram Wally World low base bird shot.  No need to bruise your shoulder and waste spendy high powered high base buckshot or heavy slug loads.

 

When brand new, the shotgun may not cycle the weak 3 dram or equal low base bird shot even with the gas turned up all the way.   It MIGHT take a couple hundred rounds for the gun to lap and break in.  The shotgun will probably run with full/high power loads right out of the box.  It is a matter of the gas setting.

 

Edited by HB.  Put on my glasses and studied the picture.  I think what I meant to say the dots on the regulator line up with that big dimple OPPOSITE from the barrel?  The dots do NOT line up close to the barrel?  My mistake.  Sorry.

 

But .... being brand new and tight, it might not cycle with the weak stuff until the shotgun gets some mileage.  Be sure to do a take down and inspection before shooting.  Crazy things happen at the factory.  Especially check the bolt group and bore.  Oil her up heavy and shoot the shit out of it.  Tell it right off who is the boss.  smile.png

Now that you have determined settings, you should screw it all the way in, then back out until it lines up with your desired setting.

 

When you try new types of ammo, run them on a more restrictive setting. If they don't cycle, bump up to the next most open until they do.
