This will warrent further looking into. I don't think an honest answer exists currently.

I don't think it would be an issue as 922r CLEARLY states the ACT of modification is what is illegal, not the modification itself. So, while the gun MAY be confiscated (who cares, your life > gun), you can claim that you purchased it in that configuration from another, or a friend did it, or whatever. It would be up to the state to then prove that there is "reasonable doubt" that you did not do it yourself. Very difficult. I would NOT want to take that case as a prosecutor (which I am not, I have not studied law, please correspond with your attorney in this matter). Another thing, who's to say you can't swap mag tubes back in a few minutes? Just don't get retarded with the lok-tite. Also, we have a bazillion threads dedicated to this supposed problem, lets not turn this thread into another.

Send it of to have it done, or paint it yourself.

+1, I didn't even MENTION weight in my comparisons, only that the OP's tube is as easly, or more easily dented than aluminum.

I have worked out an equivalent deal with another user on this board, went down Friday. Thankyou for looking out for me!

That is like saying "I normally don't floor my Ferrari, so I just run 87* gas in it." Either way, it is a nice looking tube, I just feel that Zee could have gotten a nicer one for the same or less $$ and I felt that I should outline the reasons why I felt that way. If you can't say what you've got to say with numbers, you don't have much to say. One can NEVER worry too much about tube strength

Kip is a good guy. Like I said, his customer-communication needs work, but he is honest, and a perfectionist. He will take care of you, it might just take a moment. If you can't wait, go with SOCOMguy's tubes until Kip is rolling 100% (now, or VERY soon, actually, from what I hear), but if you can wait, I think Kip's tubes are the best thing out there right now.

"Mild Steel" ? Meh. For just $20 more I would have gotten SOCOMguy's good steel tube, or for $40 more, Titanium alloy from kip. Mild-steel tubes can be had for $60 or so elsewhere. Do you know what Rockwell B 84-87 equates to on the NORMAL Rockwell scale? (Rockwell "C") It is a 3 to 6. That's right. Barrel-steel is usually 28-40 (1911 pistols are around 40, stainless varmint-guns are around 28-32, and AR-15 CMV is usually mid 30's...and your magazine-tube is likely no greater than...6.). This tube is in the same league of hardness probably as a steel Wolf shell-casing. Kip's tube= 24 Rockwell hardness Reference: http://asm.matweb.com/search/SpecificMaterial.asp?bassnum=MTA321 SOCOMguy's tube= 28-35 Reference: http://www.emjmetals.com/pdf/bluebook-h.pdf Your tube: 3-6 Reference: http://www.carbidedepot.com/formulas-hardness.htm Your Benelli M4's reciever is "Ergal" (or 7075) aluminum alloy, with a hardness of RC-6. However, this is BEFORE anodizing, so don't fear for your threads/abrasion upon installing one of the "harder" tubes. Aluminum anodizing is usually 60 or higher on the RC scale, but remember this is just a surface treatment mainly meant to prevent abrasion, not impact damage (evidenced by ejected-shell dinging). We know that ejected casings brass heads handily dent this reciever upon ejection around the port. Ergo, I state that dinging you mag-tube of the same hardness, given it's necessarily thin walls, would be very easy to do, and could result in a jam at the worst possible time as the follower/shells would not be able to travel past the dented portion if the dent were significant at all.

Yes. It is minus a few coils, but the same length.

When Benelli sends me a barrel without a canted front sight.

A re-designed spring from Kip will be out in a week or two.

*These are not my pictures, but I bought this mount as well and have it on my M4 with my T1* This is the ADM "LOW" T1 mount. As far as I can tell, it is full of nothing but win.

I have found my stock. TY ALL!

Can order them darn-near anywhere. The question is...how do you attatch?

S2K was a medium/poor performer in the test I ran. BF CLP was the winner. I did not test T-9 yet, but it should win as it has a parafin base.

Still looking, was working on a deal with a guy on here but either he has run into a computer problem and cannot send/recieve PM's, or he has decided that he is just not going to sell/already sold it and is avoiding me, or some other possibility.

Nothing about that letter is pertinent, imho. All of my M4's were built by someone else, and 922r is only about assy., not possession. So I'm not worried about it.

Upon reading this logic, I consider the Benelli M4S90 firearm to be a single item (It has a single serial # and is identified as such. A single item.) containing a combination of multiple parts. Screw your 922r.

I keep buying/selling 'em. All I need is one stock though This M4S90 is a keeper, lol. Have an Aimpoint T1 and ADM mount and a Ti tube on-order for it as well.

WTB NIB/LNIB M4 collapsible stock. PM me with info.

Wow! They changed the ratings. The last E2D I saw put out 210L on high. They used to be rated 120L, just like the Scout M600C.

Another worthy purchase

Don't let the 120 Lumen rating fool you. These lights normally put out 180+ lumens. Very bright, great lights!

It doesn't get much "lesser" than a mag-extension. Benelli or not, weak. Buy the Full-length tube. That's what the gun was meant to have on it.
