its noteworthy HOW FAST i proved you wrong in that other thread about mass on top of the pic rail,.... its even EASIER to do so here.
1. its the responsibility of the owner before modding the gun / shotgun to LEARN 922R compliance regulations and the PARTS LIST and NUMBER OF PARTS needed to make it 922r
2. putting on a Italy genuine +2 DOES NOT KEEP ANYONE FROM MAKING THE M4 922r COMPLIANT with the appropriate parts and number of same.
3. Keep it simple?????? there is NOTHING MORE SIMPLE that adding a +2 and then a USA made follower, stock set, hammer, disconnector, trigger etc......
thats FAR easier than using a heat gun to remove the 5 round BASE TUBE
and it makes the gun 10000X easier to clean the shell tube / replace springs.
Some people (for the reasons just listed) do NOT want a FULL TUBE,............NOR does doing this make it "harder" to make said gun 922r compliant.
Please dont waste my time, or the OP time posting illogical hyperbole and inaccurate subjective opinions.
922r compliance parts list / possibles, easiest highlighted in black.
Buttstock (with integral pistol grip)
Notice that the “magazine body” is in the list. This is the magazine tube. So, if you install a full length magazine tube on your gun, you are replacing the factory magazine tube, so you now only need to install two more parts off the list to be in full compliance with 922(r).
Notice that the three parts must be USA made and totally replaced. Therefore, the installation of a magazine EXTENSION does not count towards 922(r) compliance. To use the EXTENSION, the user must still replace a total of three other parts off that list in order to be compliant with federal law. The reason the EXTENSION tube does not count towards compliance is because you mustreplace the original part with the USA made part, and using the EXTENSION does not replace the original magazine tube, it only extends it.
The ATF specifically stated in the letter we received that “no paperwork or fees are required to alter your weapon as long as the barrel length is kept above 18 inches, the weapon features a shoulder stock, and the resulting firearm retains an overall length of at least 26 inches (with stock extended).” Additionally, ATF agents we have spoken to at the SHOT Show have informed us that it is not necessary that the parts are stamped with marks identifying the part as made in the USA, but it is a nice precaution that any parts one uses to achieve compliance are indeed marked as made in the United States.
It should be noted that this discussion in general presumes you are either using the Benelli OEM stock or an aftermarket stock, and NOT the Benelli M4 collapsible stock. For those using the Benelli brand collapsible stock, you actually increase the 922(r) part count by one, meaning you would need to replace a total of four (4) other parts to achieve compliance. This is because the original Benelli M4 stock is a stock with an integrated pistol grip. The Benelli collapsible stock is two pieces comprised of the stock as one piece and the pistol grip as another piece.
