Yeah, it makes sense for it not to go all the way in, given that the bolt needs to be able to compress the inertia spring during cycling.yet anther update from SDS
I apologize for all of the inconvenience, when our gunsmith was pulling parts for you, he had mistaken your picture for the S4 shotgun since they are almost identical, not the Duo-Sys that you have. The bolt does not go all the way into the cutout. He said it is completely normal for yours to stop where it does.
Which shells are you running?I just took mine out again. Failure to eject Federal Buckshot in semi auto. In pump action I got failure to feed where rounds were getting caught up at the mouth of the chamber. Guessing lifter isn’t perfectly aligned but it did feed alight in semi auto? Also had a couple light strikes as well.
Going to call SDS next week. Frankly I’d be happy to get my money back if I can. Glad I waited to upgrade it.
If I can get it to run high brass buckshot in semi and birdshot in pump I’ll be happy.

Since the transition ate my post...
Test-fired my returned Duo-Sys on Sunday. Had some initial cycling problems like Eric described, but some lube in the action appeared to fix them completely. Only ran about half a box, but the light strikes have disappeared. Assume a stronger hammer spring was responsible for both items.
Step two will be to put the Magpul stock back on and see if the issue is still fixed with that. Once I feel comfortable with reliability at that point, I will do the mag tube cut and put on an extension and new follower... I have a Wolff tube spring coming this week.
They emailed me with tracking for the gun on the return. No other communication. There was a note in the box about what they did. It took about a week to send it back from the time they received it, which is reasonably fast turnaround.How long did SDS have your gun? Did they email you before they return ship. they have had very little communication with me since I shipped it.
Even legit Benelli M3s have cycling issues with weaker birdshot. Just how the platform is...Battlehawk has these back in stock for $275. This thread has made me question if I really want one, but $275 is less than I’d pay for a 10/22 these days . . .
Benelli Nova, but you will need to cut the tube back to make it work. The Duo-Sys uses the original M3 style spring+follower retention, which is a crimp. Dumb decision, but I bet it was cheap...Any word on what magazine extension works for the Duo-Sys?
Can't say I've ever had that one happen to me. Sounds almost like a timing issue with the lifter, or you somehow dumped a shell out with the button while it was up (I don't know if that even works, I've never tried).Also, in working the action with dummy rounds, I had one fly out of the tube onto the floor. I don't know if it was a user error with working the action without "firing" the rounds. Any info on personal usage would be appreciated.
The Tac 12 is the M4 clone, right? I think that seems fair, unless you already have one.Well they called and told me that they couldn’t fix my Duo and they have had so many problems they would rather replace with Tac-12.
Figure I’ll be able to at least get my money back.
