Jason Klein Posted May 8, 2016 Share Posted May 8, 2016 I have an older (8 or 9 year old) Benelli M2 with Ghost Ring sights, shorter barrel (whatever length they were), and a +9 Nordic Components extension with follower. I have opened up the loading port, I welded the carrier up, TTI Bolt and spring kit (hammer, trigger, and recoil). I have pretty much had the same issue since new, and I am little passed frustrated. Here is what is happening: shotshells will hang up on the carrier while the bolt is back. SOmetimes the first, sometimes the last, but hangs up 1 in 10 rounds or so. Never the same # in the tube, just randomly. I thought it was me for a long time, but others have the same problem with my gun. I have tried numerous loads (heavy, medium, light), slugs (light and heavy recoil) and buckshot, all presenting the same problem. Watch the videos. Let me know what you think. I will provide more info if needed. Link to comment Share on other sites More sharing options...

CJW Posted May 8, 2016 Share Posted May 8, 2016 You probably need to replace the carrier spring, part #9 on the Brownells schematic: http://www.brownells.com/schematics/Benelli-U-S-A-/M2-Trigger-Assembly-sid913.aspx#s15319sid913 Link to comment Share on other sites More sharing options...

roxymajor Posted May 8, 2016 Share Posted May 8, 2016 The red, white, and blue ammo makes me think think your shooting the 1 1/8 oz 1145fps. The standard spec ammo for most hunting semi-auto shotgunis including Benelli is 1 1/8 oz at 1200fps. Using the 1 1/8oz 1200fps + could cut down on the guesswork and fix some of the issues. In the 1st video I'm guessing ammo, carrier spring, or some binding where the carrier (lifter) interacts with the rest of the trigger group (bad install of the extended lifter?)... Take trigger group apart and make sure the lifter is easily gliding before installing the spring. The second video problem looks like a usually Benelli M1/2 problem of shell alignment with an extended lifter (shell catches on the razor sharp extractor groove). Hotter ammo and/or Taran light recoil spring, and filing the razor sharp extractor edge down to a dull edge. Good luck. Greg Link to comment Share on other sites More sharing options...
Jason Klein Posted May 9, 2016 Author Share Posted May 9, 2016 All good ideas. This is a factory lifter that was modified. I removed the spring and it easily glides through its range of motion. Sharp edge on the extractor? I am not following there. TTI modified my bolt and cleaned up the extractor. (That is what they said that they do. I am calling them tomorrow, but would rather learn what is happening.) Is it possible that my lifter is the problem? I will get a photo of it and upload it later tonight.

StealthyBlagga Posted May 9, 2016 Share Posted May 9, 2016 VIDEOS 1 & 3: Install a new Action Spring (or even better, a Wolff XP Action Spring). Completely solves the same phenomenon in my two VM Tacticals. VIDEO 2: Looks like the nose of the shell hung up on the extractor cut (on the right side of the chamber). Check it with your finger - if razor sharp, try gently breaking that edge with a stone. Alternatively, try a different brand of shell (AA have a better crimp than some budget shells).

Jason Klein Posted May 9, 2016 Author Share Posted May 9, 2016 I already have installed the TTI recoil spring, trigger spring, and hammer spring. Or do you mean a new carrier spring? Link to comment Share on other sites More sharing options...
AustinWolv Posted May 9, 2016 Share Posted May 9, 2016 Did you use the original mag tube spring or a Nordic longer one? Link to comment Share on other sites More sharing options...
rboyes Posted May 9, 2016 Share Posted May 9, 2016 (edited) I have a fix I posted in another thread, let me take a look for it. Edit: Please see this thread. Reducing the angle of the step I point out on the bolt catch resolved the bolt hanging back problem in my M2. http://www.brianenos.com/forums/index.php?showtopic=208201&hl%2Brboyes#entry2338094 Edited May 9, 2016 by rboyes Link to comment Share on other sites More sharing options...
Jason Klein Posted May 9, 2016 Author Share Posted May 9, 2016 Austin, used the Nordic spring, but since it hangs up at different intervals, I do not suspect it. Rboyes, I'll be checking that out first thing this morning. Link to comment Share on other sites More sharing options...
Vespid_Wasp Posted May 9, 2016 Share Posted May 9, 2016 I already have installed the TTI recoil spring, trigger spring, and hammer spring. Or do you mean a new carrier spring? I think that is what he means. I just recently upgraded to a Benelli but my FN SLP started exhibiting these kind of malfunctions when the carrier spring became worn/tired.

Jason Klein Posted May 9, 2016 Author Share Posted May 9, 2016 Ordered the shoeing, and I'll be polishing that spot on the bolt stop. Kind of hoping that cures it. Link to comment Share on other sites More sharing options...
StealthyBlagga Posted May 10, 2016 Share Posted May 10, 2016 (edited) I already have installed the TTI recoil spring, trigger spring, and hammer spring. Or do you mean a new carrier spring? I meant the Recoil Spring... the spring that goes in the buttstock. The TTI is a reduced-power spring, and could be struggling to push the bolt forwards. It is a pretty cheap part to replace, and no filing/grinding/polishing required. if you still have the original spring, drop it in there and see if it helps.

Jason Klein Posted May 10, 2016 Author Share Posted May 10, 2016 I replaced the original spring with the TTI. I still have it. Link to comment Share on other sites More sharing options...
Jason Klein Posted May 10, 2016 Author Share Posted May 10, 2016 It should be noted that the exact same problem existed before I replaced the recoil spring. Link to comment Share on other sites More sharing options...
Jason Klein Posted May 10, 2016 Author Share Posted May 10, 2016 While waiting for my new carrier spring, I removed the bolt release and cleaned up the razor sharp edge that was in there. Polished it, and put it back together. Did another couple mag dumps just to check 95% better, and I may pull it back out and see if it needs more tuning. I am trying to be gentle and not remove too much material. (Sorry, I swore on this one...) Link to comment Share on other sites More sharing options...
Jason Klein Posted May 15, 2016 Author Share Posted May 15, 2016 So, after what feels like forever, my beloved Benelli M2 runs like a raped ape! Took my carrier out and polished the back edge a bit more and cleaned a rough patch on it and no more jams! Shot a 3gun match yesterday and it ran flawlessly! Thank you to everyone for the help.

Snopczynski Posted May 16, 2016 Share Posted May 16, 2016 In video #2 was the shell hung up on the side of the chamber in the front? I know on the vinci you have to dull the edge of the chamber where the extractor cut out is. Shells tend to hit that sharp edge and get stuck there. Did the gun run well before the Lifter was welded?

cas Posted July 17, 2016 Share Posted July 17, 2016 Did you "roll the nose" of your carrier slightly after it was lengthened? I had similar hang ups till I did. Link to comment Share on other sites More sharing options...

Tommy T Posted July 27, 2016 Share Posted July 27, 2016 Jason, I am having the exact same problem with my M2 that I think I see in videos #1 & #3, with the bolt satying back while the next round lies on the elevator. There were a lot of suggestions flying around in the thread, to the point that I'm not sure which action actually fixed the issue. I'd very much like to hear exactly, in your opinion, what you did to make that particular problem go away. Because I need to try it. I'm following the thread, and I hope you can find time to lay it out for us. TIA,Tommy Teas Link to comment Share on other sites More sharing options...
