Benelli is replacing it due to slightly canted front sight.

Again, all import and assembly laws. You may be thinking of that "or any possession thereof" meaning the firearm. No, it means a possession of the United States, such as a colony or territory. You have further supported the fact that 922r is a law against ACTIONS and not MATERIALS. There really is no room for argument here if you read the law and understand the wording and take it for what it is, letter for letter.

Optic. Put an optic on it. Seriously though, I think the custom shim would be the way to go. A bird gun is meant to be lively, natural, and fit the shooter like an extension of their own body. If it won't do that with a factory shim, get one that will. Correcting POI with a different sight is just a band-aid for a poorly "fitted" weapon imho.

Sadly, with Benelli, it's more often "Ahhh...I'll buy it at a high price!"

This magazine tube is made with 12L14 mild steel, heat treated to a Rockwell B 84-87. That is what that site says about the tube. Rockwell B scale is for soft metals like aluminum. Your tube is a Rockwell "C" of 3-6. Your aluminum reciever is about a 7 and it dings easily from shell-ejection. There is NO mention of "chrome molly" as you stated. In fact, the steel referenced is 12L14. This is a "carbon" steel, and often is called "lead steel" because it is so soft. It is normally used for parts involving bending, crimping, or riveting such as in bushings, inserts, couplings, and hose fittings. http://www.jprosock.com/materials-steel.html The fact that it is soft and easy to machine (at a rockwell of 3-6, it won't wear cutting tools out for a LONG time) makes it appealing to machinists looking to make a product that costs them very little. It is easy to machine and cheap to produce. Basically, it is soft, ductile, and causes very little wear-tear on cutting tools and thus has a high profit-margin as a finished product.

I am tired of hearing everyone ask about it, whine about it, question it. "It shall be unlawful for any person to assemble from imported parts any semiautomatic rifle or any shotgun which is identical to any rifle or shotgun prohibited from importation under section 925(d)(3) of this chapter as not being particularly suitable for or readily adaptable to sporting purposes except that this subsection shall not apply to-- (1) the assembly of any such rifle or shotgun for sale or distribution by a licensed manufacturer to the United States or any department or agency thereof or to any State or any department, agency, or political subdivision thereof; or (2) the assembly of any such rifle or shotgun for the purposes of testing or experimentation authorized by the Attorney General. " There it is. In all of it's evil glory. Will someone PLEASE! show me where the possession, usage, or sale, of a Benelli M4S90 in ANY configuration that is commonly whined about, is made illegal by this law. You cannot. Because it isn't. ASSEMBLY is the illegal act. As long as you did not assemble the weapon, you have committed no crime according to this law, nor is your weapon "illegal". It is the action that is criminal, not the item that is regulated. Simple reading comprehension skills will show this to be the case. That being said, my dog is a master of mechanical feats.

www.tinypic.com What MFR website are you referencing?

Cool about the FB/woodworking. Thing is, you linked us to a tube: "This magazine tube is made with 12L14 mild steel"-link from your OP, and later in the thread, you claim "Chrome Molly Tube construction"-taken from your post on page 3. Definitely not the same tube.

Yeah, it did get kinda wonky after we saw that you claimed to have bought one tube, then claimed it was a different tube, etc. We don't know what to make of it.

They work. Period. But only if you spend the money to do it right. My barrel is still at Benelli, so no pix of it at this time, but I mounted the Aimpoint T1 http://www.rainierarms.com/?page=shop/detail&product_id=843 I purchased in the ADM Low mount http://www.brownells.com/.aspx/pid=27291/Product/AD_T1_L_AIMPOINT_MICRO_MOUNT, and slapped it on the rail. I put the collapsible stock on and set it to the middle length setting. Wow. Wherever you point the shotgun, a red-dot is hovering in your FOV. Instant. Paint the target, bang. Period. There is NO WAY ghost-rings would be faster. The only thing faster than this is just "point shooting". Now if you have the OEM PG stock, you can't do this. The red-dot will be above your normal plane of sight, which means you must then "find" the dot by moving your head around like some sort of turtle reaching for a piece greens held by a first-grader with palsy. It just won't work. Irons are better for you if you refuse to buy the collapsible stock. If you have one, however, the T1 and ADM Low mount are tops. *Other mounts for the T1 include: B&T LRP (sold as a "retrofit kit" by Aimpoint): Nice, but even Aimpoint tech-support doesn't like it. LaRue: Probably the best T1 mount out there, but the recoil lug gets chewed up by Benelli's axially relieved rail. KAC: Very similar to the ADM, but over $200. ADM: Very similar to the GG&G type mounts, VERY solid. Perfect height in the "low" version.

You pre-drill the hole the nail goes into? I have NEVER heard of that practice. Then again, wood-working is not my forte.

Hrmmm...and none of these 16 penney nails bent upon hammering, no? If not, props to the carpenter who hammered them...

The tube you linked us to in your OP was $139, Mild steel, and in general, had all the atributes of a cheap zinc-coated deck-nail.

I don't think ANYTHING interchanges on these except maybe the "small parts". However, my M4 has taken birds on the wing and sligns buckshot with precision. Hunt on!

What, are head-shots non-PC at your range? Weak.

Kip's Ti alloy tubes are the best on the market, in my opnion. At $189 they include a spring, which drops the effective price of the tube to about $170 if you consider that the spring would also incur a shipping charge if ordered separate. Kip's Ti tube is 53% of the weight of the steel tubes out there, and is very strong/dent-resistant, being a Ti alloy. The machining quality is superb. Any of you who have one, know this all already. The one complaint I have heard a lot of is: "WHERE IS IT!?!?" and "WHY CAN'T I TALK TO KIP!!?!?" Very valid complaints! However, I spoke with Kip about this today. He has been fielding phone-calls about 922r, etc. etc. etc. Any of you who have spoke with Kip knows he is very thorough, and he does like to talk, and he is very polite. All of this means that if you DO reach him, you will probably spend a few minutes talking with him. Time spent on the phone is time spent NOT working on the tubes. Kip also has a personal life as well. It is unreasonable to ask him to drop his personal life. I feel that he has done very well answering his phone/returning my calls as-is. What I say all this to tell you is, Kip has been a bit slow getting back to some of you, but it has been because he had to give up SOMETHING here. Either he makes tubes, or he talks to you about tubes you wish he was making. The bottom line is this. CarrierComp is down to a 2-4 week time-table. I ordered my Ti tube Oct. 13, and it is going to be shipping this friday. Kip is getting caught up on things and now what is arguably the best M4 full-length mag tube will also be competatively available as well. While I feel that communication is key, I also would rather Kip put my e-mail on the back burner for a while and focus on making the Ti tube I ordered. Talk is cheap. Product sells. Order with confidence.

I would get the M2. I am still not sold on the Vinci.

If you violates 922r he will eatz yoo!

Yeah, that's because it is what was designed to be used with the weapon.

My friends and I have broken a few of those on our M4S90's. Very true about the need for a collapsible stock. That is why I bought one.

Neither can I, especially with so many others on the first 2 pages of this forum.

I do not know, but googling around should turn something up.

I agree 100%, however, my issues came when using MEAN stuff, like 3" Remington #4 Buckshot and the like. The inertia of recoil compresses the mag-spring under the weight of the last shell, and cycling does not occur properly. The shell, as you stated, does not make it fully onto the elevator as it has to return from it's trip deeper into the mag-tube caused by recoil/inertia.

I agree with you academically, Stranger, but I saw a test where a guy took a magazine, compressed the spring, left it for 6 months, then took another new magazine and cycled it 20 times or so. The 6 mo/compressed once spring was still shorter. I dunno what to think anymore, but I know scientifically your post is 100% dead-on. *Haha, re-reading my post, I was reminded of the merchant character on the Resident Evil PSII game who whips open his trench-coat like a mall pervert and yells "Hello, Stranger, got somethin' that might interest ya!"

Meh, I still feel that buying a $1500 shotgun and then screwing a $139 tube into the reciever instead of a $189 tube that is superior, is pointless, from an economical standpoint. Will it be okay for range-use? Sure! I guess I just think differently. If 2 nails will do, I use 5.
