If the gun cannot be imported and cannot be assembled, how can it legally be possessed without having to comply with 922 and 925.

The M4 cannot be imported for civilians in any such configuration other than what Benelli offers to the public as it cannot be deemed particularly suitable for or readily adaptable to sporting purposes. Here is section 925(d)(3): (d) The Attorney General shall authorize a firearm or ammunition to be imported or brought into the United States or any possession thereof if the firearm or ammunition— (3) is of a type that does not fall within the definition of a firearm as defined in section 5845(a) of the Internal Revenue Code of 1986 and is generally recognized as particularly suitable for or readily adaptable to sporting purposes, excluding surplus military firearms, except in any case where the Attorney General has not authorized the importation of the firearm pursuant to this paragraph, it shall be unlawful to import any frame, receiver, or barrel of such firearm which would be prohibited if assembled;

After September 2004, Mossberg shotguns were no longer subject to any AWB restrictions because they are domestically produced. Provisions prohibiting imported semi-automatic assault weapons were added to the 1968 GCA in 1989. They will be here forever and did not sunset in 2004. These laws are the reason why Benelli military shotguns, SPAS-12s, Heckler and Koch 90 series rifles, Steyr AUGs, FNCs, AKs, Dragunovs, and whatnot have not been imported since the early 1990s and now bring premium prices. New versions of these guns are assembled in the US with US made parts. The Benelli M4 is made entirely in Italy and is subject to import restrictions and cannot be assembled into a non-sporting (M1014) fashion unless it contains a select number of US made parts.

All parkerized steel gets a thin coat of Breakfree CLP for rust prevention. The moving bits in the bolt carrier and the carrier track in the receiver get Lubriplate grease because oil works it's way out of these areas while in use and in storage.

You may want to start using grease instead of oil. Oil runs out of areas where you want it into places you don't and gets blasted away under firing. Grease stays put and offers much more protection against friction.

Nope. They attach differently. The M1 and M3 share the same stock though.

Birchwood Casey Aluminum Black will touch up those areas like new.

No need to remove the barrel or bolt carrier, the trigger group is the only thing that needs to go to unscrew the stock.

It removes the same way as the pistol grip portion of the telestock, remove the trigger group and unscrew the stock.

The M3 does require a different extension. Surecycle makes one.

Minimum barrel length is 18" for shotguns, 16" for rifles.

With the cartridge drop lever down the bolt cannot be locked back, rendering the bolt release unusable. What is happening with your gun is the bolt is being held back by the shell carrier as it comes up when the bolt carrier moves forward. Probably because you are riding the bolt forward, the bolt carrier needs full forward momentum to operate properly. To lock the bolt back with the hammer cocked and cartridge drop lever exposed you must push the cartridge drop lever in then you can pull the bolt carrier to the rear and it will lock, you can then use the bolt release.

In that case, Benelli lists capacity on both the website and in the catalog as 4+1. Maybe mine is broken.

7 A factory 11707 will hold seven total 2 3/4" rounds. Five in the limited cap magazine, one in the chamber and one on the carrier.

I don't like Duracoat, it's too glossy and has a thick, bumpy texture. I do like Norrells Moly Resin . It's very smooth and extremely thin, very durable against scratches and nearly indestructable to solvents. Grayish-Black flat is a perfect match to real parkerizing. Here's one of Joe's great M1014 tubes I refinished with Grayish-black flat Moly Resin: Moly Resin texture on an M1 Caribine bayonet lug, see how the engraving is unaffected because the finish is so thin:
