"Green nickel" ?? ... I smell an environmental rat. Just a guess but ... hard chrome plating is not a particularly earth friendly process so go to something more "green" and see how it holds up. " Flakes" don't sound very good to me. Joe B

Seemed pretty heavy too at 7.4 oz but remember that I said ..."If the steel one is configured the same as the aluminum one" .So who knows ? Joe B

Since no one answered this, let me take a stab at it. I don't have a steel extension to weigh. The aluminum extension weighs about 2.5 oz. If the steel one is configured the same as the aluminum one, then it should weigh about 7.4 oz based on the relative density of Al vs steel. Joe B

Are there any markings on the 7 rd that would indicate maker/ origin? Joe B

I can answer that question as the topic comes up when prospective shoppers are looking at the options . OEM 5 rd + dummy extension - 9.8 oz 7 rd FFT Ti tube 5.6 oz One of my 7 rd thin wall 4130 steel tube 8.8 oz I don't have a weight on the OEM 7 rd steel, but likely heaver that mine after you load them all up with OO buck you will not likely notice the difference. Joe B

Good tutorial and great photos tell the story ... Thanks for sharing Joe B

If you have not seen one .... a tornado brush is not like a normal metal wire brush. It is made with stainless-steel wire that is wound around the stem in swills so there are no sharp points touching the barrel from the wire. I use a tornado on all my shotguns and see no adverse effects. Just for info, your mileage may vary.... Joe B

Welcome ... "stay tuned" lots of great info and expertise here Joe B

When someone buy a 7 RD tube, I always suggest that they first try running the OEM spring... if all functions OK, go with it. My understanding is the Benelli uses the same spring in 5 rd and 7 rd tubes. Joe B

Rx, you are in Canada, would there be any issues with a US made 7 rd tube being used in Canada? How about shipping one into Canada? Joe B

Try with an original 5 RD spring, I understand that Benelli uses that spring in both the 5 and 7 RD tubes. Also leave out the retaining clip. just remember to use care when removing the cap. Joe B

A good photo might help us understand Joe

Just a thought on a possible POI change with a Ti mag tube. The coefficient of thermal expansion of Ti alloy is 5.3 vs 7.0 ( 10-6 in/deg F). since the barrel is steel, there may be something going on with stress and barrel deflection in the vertical plane as the assembly heats up..... Would have to be very slight effect, indeed. And while we are on the subject of 7 rd mag tube weights... here is some info. Ti tube 5.3 oz. . One of my thin wall 4130 alloy steel tube 7.0 oz. For comparison, the factory 5rd with the dummy extension assembly weights 9.3oz Joe

I'm partial to nice wood on a firearm, looks real good. Now get rid of the "space gun" extension and it'll be beautiful. Joe

The last ditch solution would have been to bore out the thread and install a threaded bushing, it appears that there is sufficient "meat" to accept a thin bushing. Joe B

Too late now, but for future reference, MAPP torch is quite a bit hotter than propane, have to use caution with MAPP on thin or delicate parts. Joe

Search on this forum, lots of info here Joe

Longer but compacts better?? ... got me thinking, count the number of coils on the two springs.... the same, 48 coils on both. Should compact the same you would think. Joe

I'm an old school guy, So, my first "go to" is to convert the metric to imperial to see if there is a common item here in the USA. Sure enough the 1.20 mm wire is = to 3/64 inch ( .047) ... just saying ! Joe

Ask them if you can tape on a length of broom stick to make it 24 or 30 or whatever makes them feel better !!!!!!!!!! Joe B

The initial defect would indicate a poor sweat solder joint between the sight base and barrel. There is a good chance that the sight is not securely attached to the barrel, a hard bump from the side might knock the sight base right off. Also , a good possibility that the brown rust straining will reappear through the new finish. All in all , not a good situation. Joe B

Sometimes you only want one more! Apparently in the Pepoles Republic of New Jersey you can only have six in the mag. I had a request to make one of my custom "NJ Specials" for a fellow there. The extension replaces the OEM extension, allows 6 in the tube. Joe

It sure looks like rust from acid soldering flux not having been properly removed and neutralized.... may even indicate an incomplete soldered joint. Joe B

To facilitate soldering acid flux is used. If the flux is not completely washed away and the residual neutralized rust will result.... like brown rust. Joe B
