Interesting video. I bought one of these shotguns from Walmart a couple years ago and only planned to shoot light loads with it so I drilled the gas ports bigger. Now it functions reliably with standard 2.75" birdshot.
Interesting. Was it the 3-1/2 version like this one, or the standard 3" version? What piston do you use, the ringed one or the heavy one? My goal was to get away from the ringed pistons because come off and cause problems.
@@propdoctor21564 Probably came with the ringed one. But it sounds like you're on top of it and have it working. I may look into drilling out the holes someday just to see what happens. I do have an extra barrel or two I can play with.
Yes, the piston is what I have been trying to design for quit a spell and finally figured out what needed to be done. It performs flawlessly in all of my SAS models. I can even shoot 2-3/4 in the 3-1/2 inch shotgun, like I show in the video. There are primarily two reason for a failure to cycle 3" shells. One is the shell itself. If it's 3 inches after being shot, it will not cycle in the 3 inch versions because the ejector is not set up for a full 3 inches. It's set for the European 3" which is about 1/8" or more shorter. The other is oil. I cannot express how many people fail to properly oil their automatic shotguns. Whether it's a Hatfield or other brand. Even Stoeger's, Brownings, and Benelli's need to be oiled to function properly. It's a given. If all is well there, I would then look at the extractor for proper function, spring pressure, and ability to grab. I would even look at the trigger assy and see if the carrier spring is dragging against the trigger housing. You may want to buy the ringed piston and see if it works. Some shells do not have the gas power to function all types of shotguns. I have seen this even on top end shotguns.
I rigged one up. I drilled and tapped the receiver and put a Mossberg scope base on it. But you can only use the back part of the receiver and base and not drill into the front side because the metal is too thin. The base is set at 1/2" hole spacing. I then drilled another hole 1/2" away toward the center and then drilled 3 holes 1/2" apart into the receiver to match. I bought 3 new longer screws that would go all the way into the receiver for strength and ground them off flush with the inside of the receiver. I had to take them in and out until flush. I used a course thread to prevent cross threading of the screw because the receiver is aluminum. Course threads hold better in aluminum. I've had no issues. I put a scope on at first and then later changed it to a reflex sight. But you may want to check with Hatfield and see if they offer a scope base.
Try shooting only one shot in it at a time and see if it's kicking it out. If it is, then load two and check to see if it's jamming the next shell under it. Maybe bend it out a little. Remove and check the extractor and make sure it is smooth on both sides and spring is clear of debris. Check trigger assy for rub marks on the side. Also, the shell lifters are sometimes put in with the wrong piece. A left had unit instead of a right hand unit. This will rub the inside of the receiver and cause it not to work.
@@jeffclark8696 I am assuming the shell is coming all the way back, and you have an empty shell on top and a loaded one in the bottom of the receiver. If one shell is shot, it does what? Close the bolt back with the empty in it? Stay open? Or Shell part way out? If two or more shells are in it: does the next shell leave the magazine when fired? Does it go under the fired shell? Will it eject 2-3/4" shells? Does it cycle the next shell in the magazine? Any issues when shooting 2-3/4" It is cycles the 2-3/4" just fine, I see no reason for it not to cycle the 3" shells other than they are too long and you need to get another box of a different brand.

@@bgdesignandsolutions I bought the 3-in version and it only came with one piston

Mine will still will not cycle 3 inch and I have the heavy piston.
When I purchased my shotgun. It came with 2 pistons one in the gun and one in the box.
Which one is which?
I take it this is the new design. My spring is in the stock.

Can i buy one from you cant use this gun due to hatfield going out of business
Can you put some sort of sight on that gun? Red dot or something like that

@@bgdesignandsolutions sounds good. Thank you very much!
We’re can I get a rigged piston
I made 2 of them on a lathe. They are not a purchased item. I have considered finding someone to make them for market.
If you want a ringed piston, check the Hatfield website.
@@bgdesignandsolutions it doesn’t show anything on there that u can order
@@brookscline4382 Wow, you're right. I just saw that. First I heard of this. Bummer. Maybe look on ebay, I've seen used parts on there before.
@@bgdesignandsolutions yeah might have to keep a eye out on ebay
Almost a year playing around with a tokarev ttf 12 apex field shotgun not cycling gaas system looks identical to Hatfield

Also it is 3 1/2 version
MINE WILL NOT CYCLE 3 INCH AND I HAVE THE HEAVY PISTON
You may want to get a ringed piston.
@@bgdesignandsolutions I have both. It still won't cycle 3 inch even loads orr 1300fps.
@@jeffclark8696 Does it jam? Does the shell start to come out? Does it open the bolt? Is there scrapping on the top of the receiver inside?
@@bgdesignandsolutionsNot ejecting shells

It is cycles the 2-3/4" just fine, I see no reason for it not to cycle the 3" shells other than they are too long and you need to get another box of a different brand.
