    Wish I knew myself. I looked at the assembly and it appears the spring and detent enter from the front of the barrel hanger. It's hard to see what actually retains the detent though. It looks like the area is swaged with some kind of punch or crimp to prevent the detent from coming out. This seems really difficult to do yourself without whatever specialized fixture they have for doing the job.

    The only way it appears it can work is the barrel is deformed around the edge which stops the detent at the shoulder shown above.

    I bet the 870 detent staking tool would do the job. I think I have one around the shop....somewhere https://www.brownells.com/gunsmith-tools-supplies/shotgun-tools/staking-tools/870-detent-staking-punch-prod25277.aspx

    An automatic center punch would work in a pinch. A third hand to hold the detest and spring in place while upsetting the metal would help.

    The olders ones aren't made like the riveted ones. you can interchange them.

    True, the older guns came out with a cast link that would occasionally break, same with the original Super Black Eagle (I've seen 4-5 broken parts over the years). Probably why the part was redesigned to use 3 sandwiched/rivets steel flat sections.

  3. The standard Nordic +5 tube(see below)  is just a bit longer than the 21” barrel. Nordic also lists a +5B that is advertised as being a match to the 21” Benelli M2 barrel length. The standard 5 tune is 11.60” long, the +5B is 10.83” long.  Nordic tube lenght info

    Some barrel clamps can impart pressure on the barrel and affect POI. There are methods for installing in the Nordic clap that can negate the clamp's affect or MOA Precision makes a “free floating” clamp that does not affect the POI. MOA Precision clamp

  4. If you dry fire the gun (empty chamber) will the action open easily? If it does open, try a dry fire with a little backwards pressure on the forearm to see the action still opens. We are checking to see if the Bolt Latch is disengaging when the hammer falls.

     

    Does the interior of the chamber feels smooth with no rust or plastic buildup?

  5. What brand and type of ammo are you using when the problem occurs?  If it is the Winchester "Universal" or their similar promo ammo (silver metal rims, ribbed red plastic hull) its an ammo problem.

  6. Has it always had this problem, or did it start after some period of working well?

     

    Which brand and type of shells are you using ? What is the shell's velocity and shot weight?

     

    Have you ever removed and checked the inertia spring inside the bolt carrier? (There was a run of Stoeger inertia springs a few years ago that would break)

    And you'll create a SBS (short barrel shotgun) in the process.  Tax stamp needed and IF you can get a CLEO signature....

    The NFA/ATF no longer requires a CLEO sign off (as of July 2016) ...but it does not matter in this case. As far as I know New York does not allow Short Barrel Shotguns (less than 18" barrel) https://www.nationalguntrusts.com/blogs/nfa-gun-trust-atf-information-database-blog/new-york-state-nfa-rules-and-allowable-nfa-items

  8. On the 1301 the lifter drops when the hammer falls. What makes the lifter drop on your Benelli mod?...or just go shoot it,  I want to see it work! ?

    Figured out an issue with installing the 20 gauge shell stop latch. You can not use the M1014/M4 follower; a M2 follower or similar must be used. Works 100% now.

    Yep, the hinged 20ga latch holds the shell just a bit father forward than a 12 ga latch (and can contact some followers)...and don't try to drill & tap the 20ga latch for an oversize release button.

    One of my lil side projects finally arrived. Pretty much a drop in ball detent to hold up the lifter while loading. To reset the, the bolt body will push the carrier down.

    Can you go directly from loading the mag tube to shooting, or do you have to pull the bolt back to get the lifter to drop first?

    @Steve Rose  Was that for the M4 or M1 barrel?  I have a M1 and I believe you told me it would not work for the M1 factory barrel.  Maybe I misunderstood, I hope so.   Thanks 

    M4 factory barrel.

    (The short M1 barrels are quite a bit thinner)

  12. Are you sure the width of the hammer is the issue? A hammer disconnector hook that is too tall can hold the hammer back like the picture you posted – but you will NOT be able to pull the hammer back up the correct position after cocking the hammer.

    If you CAN pull the hammer up into the correct “cocked” position then the “too wide” diagnosis is probably the right one. Coat the hammer with a black or blue Sharpie marker then install it. Functioning the hammer a few cycles will wear the marker color and show you where any contact is occurring.

  13. It is really just an extended and ported choke tube with wicked looking teeth on the end. The “no slugs” comes from it being an “Extra Full” constriction. Carlson also marketed a Cylinder constriction tube in the same style that was OK with any shell type. Both are showing "out of stock" at Brownells and Carlsons

    It seems that the Federals are the culprit in that an inner plastic cup is used to cap the powder and little shards of that seem to follow but don''t get out the barrel but fall down into the gun fouling the trigger/hammer assemblies and stop the firing pin?  When we take it apart, there were a bunch of them in there and we figure they are stopping it from shooting.  Last night was really the worst, shooting better ammo is probably the answer.  Cheap ammo works in most guns but not this one.  I am buying Winchester AA's for Preston for the rest of the season.  His entry fee covers the cost of ammo but maybe we can use that for practice in other guns.  Thanks so much for the quick responses.  Great forum.

    Thanks again, have a great day,  Jake.

     

    In my experience the Remington "Gun Club" ammo is the best of the lower priced stuff.

  15. One other thing....I have seen some of that cheaper Federal ammo that has slivers of the plastic hull protruding around the metal rim. That can cause the shell to not seat fully into the chamber and stop the bolt from closing. Inspect a few boxes of shell to see if your ammo exhibits that problem. I used to use the WalMart Federal ammo too but started having issues with its quality. I now use only Winchester AA ammo in my M2 and SBE. Yes, the ammo is $2 a box more expensive, but ammo related issues just don't happen now.

    My grandson worked on the farm picking rocks and more to purchase this for shooting Trap in the Minnesota High School League.  Tonight I watched as his 12 ga Benelli Montefeltro mis-fired 5 or 6 times within 50 shots.  They are shooting some cheaper federal ammo but come on, that seems ridiculous for a shotgun in this price range.  Another on the team has the same problem.  Might be the ammo, but nobody else has problems.  The worst part is that he seems to loose confidence or rhythm and misses quite a few after this happens.  3 misses for sure that one time.  He is chasing that elusive 25 hits and this gun is really hurting him.  Is there a cure or should I just buy some more expensive ammo?  He likes the gun to the point when I offered him my Browning over and under, he wouldn't try it.  Pride of ownership I guess and I like that.  He has another shoot on Monday, HELP!!!!

    When on the line and loading his gun is your Grandson placing a shell into the receiver then pushing the bolt release button to let the bolt slam shut? (That is the way to do it).

    If he is holding the bolt handle to let the gun close slowly, or in any way hampering the gun's bolt from closing, that may be the cause of his misfire problem.

  17. I looked at a couple of Benelli bolts today and did not see any with that mark. Given the location I suspect that the assembler missed the mark and hit the edge the bolt when driving the bolt handle retainer pin into place, or the bolt fell off a table somewhere along the way.

    From the picture it appears to be a cosmetic issue. Unless your bolt shows evidence of a crack going into the body of the bolt I would not worry about it.
