Though a blunt nylon, or plastic punch is recommended over the bolt handle for the axle bush.

One of the potentially useful features of the M4 is the collapsible buttstock.[...]Collapsing the buttstock shortens the weapon by almost 8 inches, allowing easier storage and transportation; furthermore, it permits better maneuverability around tight corners and over obstacles.

M2 11006 = 12 gauge = 18.53 mm bore diameter (± accepted manufacturing tolerances).

Some of the better 2-3/4" defense rounds for the home (most are reduced loads): Hornady TAP FDP (max load for max penetration and accuracy over a distance in 00) Federal LE Tactical (inexpensive, general home defense 00 w/ FLITECONTROL) Hornady LE Tactical (tighter manufacturing tolances than Federal LE Tactical) Brenneke Tactical Home Defense (knock down slug for armored intruders)

Unless the cause of a failure to cycle was due to stress failure on a part(s), or impingement caused by third-party accessories, or ammo, disassembly followed by a thorough cleaning and proper lubrication and the use of heavy loads solves most, if not all FTF and FTC related issues.

10-15 ft-lbs. ought to do it for the choke tube. Typically less. I prefer thicker choke grease over CLP as it provides for anti-seize properties and seals the choke entry seat, helps prevent wadding from accumulating in the recesses. At least for the initial rounds of your session. Please do disassemble the recoil spring tube assembly. No better way to learn about the M4 than to take it apart and put it back together again. The spring is of carbon steel. Small, needle-nose pliers are great for removing the stock retaining ring. The stock retaining screw unthreads clockwise when facing the barrel. IIRC, the screw is about 1/2" in height, be awary as the spring will eject with fair force as the screw reaches the last thread. I treated the spring and the tube with MILITEC-1 and lubricated with Weapon Shield before reassembly. Compressing the spring back into the tube is perhaps the most difficult part of the process in terms of the amount of physical force required, but nothing outstanding. I prefer to set the spring to the factory default tension, you may opt to increase the tension (for faster medium to heavy load cycling with reduced reliability for lighter loads) by threading the retaining screw further down. $1600.00 including tax is a good price for an 11707, at least in CA.

I do not believe Caligvla claimed the Tri-Ball was a problem as he likes the rounds, you just have to follow his threads .

Any authorized Benelli dealer. The above mentioned Numrich, Brownells and Mann & Son Sporting Goods are the big three online authorized dealers.

I have both. Your friend may have his/her reasons, but none that would sway me from choosing an M4 over an M1.

Sniper's Hide, eh? So that is where we can find you when you are not here...

Of course it would. Fit a 30mm Optotronics, or 26mm Wicked Lasers device in flashlight rail mount, sight in to your desired range and you are good to go. You see it on carbines all the time.

It is referred to as carrier loading. Review the M4 Operator's Manual - United States Marine Corps available at M4 Spare Parts List & Manuals.

Likely an indication that the issues brought forth here are being investigated and hopefully resolved. The M80 is still listed on page 51 in their Tactical Products 2008 Catalog.

You can most certainly beat their flashlights as I own nearly every one of their Millennium series of lights . See Beamshots: Mac Mini-HID (MOP) vs. SureFire MN16 and post #22 and #114 of the Polarion PH-50 Main Thread .

Good job on the quick clean guide, tucker301 . I might just do something similar for the M4...

The inclusion of part numbers as referenced to factory stock. For example, authorized dealers reference the rear sight screw as 70061 and not 127J as depicted in the spare parts manual.
