The hole is supposed to be there. Nothing covering or blocking it. The system basically uses the initial gas burst to push the piston rearward and cycle the action, then vents off excess gas.

What's your thoughts in reducing the size of said hole in order to get a little more gas to the action??

It vents at the end of the piston stroke, so not the best place to start.

I would start by slightly polishing the fire control parts to take out some of the snagglyness, then maybe slightly increase the barrel ports.

Both of those are done...guess it just needs some more shooting to get it going.

Here is my long boring ass read on my sas-12. I picked one of these up from centerfire a few weeks back. Its a DDI import and not one of the older Brolin or century sas-12's. Looks Identical though. Brown furniture and all. I picked it up from the ffl and stripped it. I took the plastic off and set it aside and stripped it completely. I heated it up with the heat gun and then hosed it down hot with engine Autozone store brand de-greaser. I used a full can of it. I didn't do any of the fluff and buff like most have or anything else top it but clean off all the sloppy grease. I will probably though. That can only help as its been noted.

I had two boxes of Federal Hi Power 12 Gauge #6 I think it's like 1350 or 1330fps. I have two 3 rounders and a two 5 rounders. The 3 round mags ran great but the 5 rounders always had issues with the second round . Seemed to chip the edge of the crimp off on a few on the second round of the 5 round magazines.

I stopped using the 5 round mags. On a side note the 5 round mags hold the bolt open on mine at least on the last round. The 3 round mags do not hold open the bolt on my shotgun. After I started using the 3 round mags solely the gun functioned fine. I didn't have any bird shot with me but I did have some wax slugs i made from target loads over Christmas. These shot accurately in the gun. Well for me at least. I was able to hit steel at maybe 75 yards with them after I learned where to hold it. They didn't cycle the gun and I didn't try loading the mags with them. I was just messing around with them anyway. They were made from walmart clay 100rd bulk pack junk. Quite a friggen thump on the steel. Lots of fun I felt.

After 50 rounds of the able federal ran dry I zipped up to the nearest fun store and bought a few boxes of estate shells that had the same specs as the above federal. I think they were like $13 for 25. I came back and ran though's. It ran all those with no issues and seemed to a be a tad hotter than the federal but who knows. After that I ran a few $5 walmart brown box military buckshot boxes through it. It ran those alright with no issues but a little slow for the action but no jams.. Might just try either just loading 4 in the 5 rounders and maybe leave them loaded for a bit and see if that works.

So all in all it seems to function just fine with the above high brass and is accurate with wax slugs with them being loaded on at a time. It needs a Butt pad bad. after I guess 185 rounds and most of them being high brass my shoulder is beat. Im going to take the plastic butt pad off and see if i cannot find something for it. I have spent a ton more on firearms before and had much worse luck so there is that...

It a Pretty big shotgun for me. Im only 5' 7" or so and have short ass arms. It isn't overly heavy. Mine has a Aluminum receiver. I thought I heard they were steel but that may have been the hawk pumps I remember reading about. Mag dumps with the 3 round mags all ran fine.

I like shooting wax slugs in it. The long ass barrel lends to pretty good accuracy with them.

I only have 1 other Semi auto shot gun to compare it to. I have a tristar atac 12 gauge and it took a long time for it to begin to cycle bird shot and sometimes it doesn't with that shotgun.

Fit and finish looks ok. Vent rib is a little wavy gravy when looking down it but it doesn't hurt accuracy. Plastic is cheopo on it so I may just check into looking for wood for it.
Im happy with it so far. The $13 estate stuff is cheap enough to have a decent time with it I may want to take my 1oz slug mold out of moth balls and make a few of those.

I already had a Hawk 982 on Layaway with Robinison trading post so I'm anxious to get it shipped so I can jack my shoulder up more.

I picked up one of these. For $139, I can deal with having to work it. Hell I spent a crap ton on parts restoring a Rem Model 11, so we'll see how this goes..

For $139, for a semi auto shotgun, even if you have to teak it a bit, that is great.

I have been looking at a replacement barrel for my Remington 870 and the cost for just the barrel is higher than the whole SAS12.

With that said, if my skin depended on it, I would trust the 870 to work as needed, I would not trust it to the SAS12.

Does anyone have some shots of their gas ports? Mine are pretty close to each other, and I can't see how that thin of a wall would hold up over time. Also their idea of a 26" barrel = 27.5".

Rib is metal, and a little wavy.

Probably going to contact centerfire. I cleaned the cosmoline off the barel and it looks like there's no finish on the barrel at all.

I'm going to clean it again tomorrow with degreaser, but it sure doesn't look pretty. Also Rio Buckshot will not fit in the mags.

Rio are like S&B shells. They measure almost 2-3/4 before being fired and will not work with these shotgun mags. It is my understanding (SAAMI specs) that 2-3/4 shells measure 2-1/2 before being fired and 2-3/4 after. FWIW

Shells like this work good for everyone I know with SAS12's.

Looks like standard finish. Just looks like it's been banged around and scratched up.

I'm about done converting one of my 3 SAS-12's to pump. Will be able to switch back and forth between pump and semi auto, by easily hand-adjusting / blocking the gas port without disassembling the gun. I think I would trust these way more as pumps anyway, when it comes down to self-defense. Great project guns. Once people see everything that you can do to them, some will regret not buying them while they can, for the cheap price. Also have a high capacity mag prototype I'm going to test sometime this week. Still no regrets spending $139 on these beasts.

KC that sounds awesome. You should post a thread on how you did it. Also if you decide to move ahead w a prototype let us know. It would get me off the fence right quick to get one or two

I will get some photos up when its exactly how I want it. Basically, I milled a notch along the bottom of the factory handguard, attached a vertical grip to the action arm under the handguard with a steel rod, with a metal liner inside the handguard to work as a sort of track and reinforcement so it doesn't end up wearing the polymer handguard out. You can pull the vertical grip back and it moves the action back, and it is still spring-loaded, so it pulls itself forward without any effort on my part. I also cut a notch into the gas block and fabricated a little plate and switch that moves over the gas port hole in the barrel to block it. You can move the switch down and it opens it up to semi auto, move the switch up and it blocks the gas and turns it into a single shot, and then you can pump it to cycle. I really like how it's going. I think you can picture how it works, if you've disassembled your SAS-12 and know what's under the handguard. Hope I explained it in a way you understand. I love these cheap bastards.

Next step is to make it ratcheting, so the grip doesn't move during semi-auto fire. I kind of like it as a pump-only shotgun, though, to be honest. But I want it to function 100% both ways. I may attach it slightly different, so it is attached to the factory handguard, and only engages the action when you pull it rearward. Easy way to make it ratcheting. Also add some kind of locking mechanism so it can't move on accident when im semi-mode.

Cool. Sounds deceptively simple.

Except for "I also cut a notch into the gas block and fabricated a little plate and switch that moves over the gas port hole in the barrel to block it."

Let's just say HS shop class was not my forte. And I had to choose the frickin skeleton key in wood shop!

Rem buckshot good.

Seems like these are a mixed bag on what ammo they like. Mine is still running good a few hundred rounds later. I never got around to any more mods I've been enjoying running the federal bulk loads through it as it is. Just a smooth shooting gun.

For anyone interested in easily running a red dot or other optic on the SAS-12, a Ruger 10/22 rail matches the profile nearly perfectly. I'm about to drill and tap one of my SAS-12's to use the cheap $9.00 NCStar 10/22 rail that lets you see through and use iron sights. Same rail I use on my 10/22's.

Rio/S&B are Euro roll-crimped 70mm-ish shells, not true 2-3/4" shells. Try the star-crimped, high-brass PMC #4 Buck from SGAmmo. That will fit in the SAS12 mags.

So finally got to play with the pair of 5 round magazines yesterday.. Spring pressure is not right, kept getting ride over jams.
The magazine spring is basically a AK magazine spring, so that is an easy fix.

Good to know. Spring tension sucked on the 5rd I have.
