And what would you be wanting for this beauty? My wife would kill me but I hafta ask...

Start high, that is a sweet thunderstick! I would not ask less than $4500 initially, you can always come down if needed. I'd be surprised if someone doesn't snatch that up.

Hopefully StrangerDanger or one of the other experts on here will reply to you. I'd make sure your shells aren't getting hung up anywhere, polish the tube inside with steel wool but don't lube it. There is a thread on this forum on how to do that. Get some good, heavy dummy rounds to cycle through and see if you can figure out the problem. My GUESS is that the 7 round tube isn't quite flush and the shells are getting hung up there or your spring isn't pushing them out with enough force or both. Your problem isn't normal and you can fix it, you'll learn a lot doing it as well.

The Panzer M4 is a knock-off of the Benelli M4. I have 2 Benelli's, both run just fine as fast as I can pull the trigger so I'm not sure what is the problem with yours but that isn't normal.

I mount my flashlight under the mag tube for a couple of reasons. 1) because it does stick out and could be a snag hazard and 2) it avoids shadow casts from the barrel.

No, not without modification if at all.

Do you mean compareable or compatable? I believe the Urbino stock will fit the M2 & M3 but others will not fit both.

A mil surp M-240 sling is what I use. Meant for a much heavier gun so it's well padded, around $20 and works great with a pair of QD sling mounts. Available in any color you want, as long as it's black.

It is a critical part that could easily be lost under stress. Best to have a spare or two was my thinking and I, personally, like a larger knob than the OEM.

I would contact whoever did the work and let them know of the problem; it doesn't sound normal.

The 7 card interferes with my hands on a 500, maybe I just have big hands.

They wanted $25 for a wrench for the front sight, it was $6 on Amazon.

Robb, you have absolutely outdone yourself with this, it is beautiful! I cannot wait to install and try it out. The price point is fantastic as well, thank you!

I'm with Ben, I have both though the "black" one I had Cerakoted bazooka green.

I find benefit from the c-stocks ability to shorten the gun for storage, the M-4 is not a small gun and would not fit in the case I use without it. I am eagerly awaiting the rx-arms 6 position recoil tube. I can shoot mine presently from either the middle or third notch but neither feel quite right. I'm confident the extra positions will rectify that.

Welcome from Texas! 🖐🤠 Looks like you got a nice piece there pard!

It hasn't damaged any shotgun barrel I've ever used that in. Barrels are tough and they're smooth bore, it would jack up rifling though. It's the same method you use to polish the inside of the mag tube and they're not barrel steel. I've had buildup that, no matter what I did, would not come out and that got it out. The brush is bronze, much softer than steel. That little bit of buildup isn't going to affect the shot anyway though.

Get a cleaning rod that you can mount to a power hand drill. Here is one from Brownells although others make them or you can make your own. https://www.brownells.com/gun-cleaning-chemicals/cleaning-rods-amp-accessories/cleaning-rods/drill-chuckable-shotgun-cleaning-rod-prod20413.aspx

We're all human Dave. Glad you found your problem and happy to help; load 'em up my friend!

Sounds like you have a limiter in your tube.

Looks totally legit. 🙄

Same problem as last time, error message when trying to read posts.

I have 2 of these GG&G bolt releases and have never had a problem so I am with SD in guessing the spring wasn't seated properly on installation. I used a pair of hemostats to hold it in place as it was difficult with normal size fingers; worked like a charm.

There was a thread on this last year, Fetter will fit 7 but they're from Russia and I have not seen any for sale in quite a while. Fortunately, for me, I bought a boatload at the time. Even with 6 in the tube, 1 ghost load, 1 chambered and 5-7 on a side saddle that's a pretty hefty load out on board. I suggest a "match saver" as well. https://forums.benelliusa.com/topic/24945-fetter-00-buck/#comment-164436

I've been following your thread, you replaced the OEM trigger to make it 922r compliant. Was there something else replaced that took it out of compliance? Maybe I missed it; I have 2 M4's and have never felt the need to replace the triggers as they work fine.
