Assuming that the M4 Entry shares the same mag tube cap as the standard M4, you can purchase a Nordic components extension made to fit the M2.

Offers welcome.

Welcome to the site. I'm just across the Potomac from you and also own an M4. Have had mine for over a year and have done many mods (including the CC tube). Let me know if I can help with your installation or if you want to try out some mods before you invest. Here is my CC tube with a three round Nordic extension (on the left). This gets me to 10 in the tube plus one in the chamber and one ghost loaded for a starting total of 12. I sue mine for 3-gun competition. The front (and rear) sight has been removed for a clear view thru a Trijicon RMR.

Bump with Price Reductions.

No, my M2 is a field model and has a 21" vent rib barrel.

Here is my M2 with a +5 Nordic extension (for 8+1). However, you don't need to worry about extending past the muzzle. Here is my M4 (on left) and FN SLP (on right) both extended for 10+1.

I just removed the hardware and left the base. Does not interfere with my optic. It's the gun on the left.

I use mine for 3-gun. Mods include: 1) Carrier Comp Titanium Full Length Mag tube and follower ($200) 2) Nordic Components M1/SBE +3 mag extension ($75) (brings tube to 10 plus one in chamber and another ghost loaded for 12 rnd start) 3) Briley Benelli Crio Plus Spectrum Extended Choke tubes (Lt Mod, Imp Mod, and Full) ($220) 4) Scalarworks BOR rail ($120) 5) Trijicon RM07 (RMR 6.5 MOA adjustable) ($600) 6) GG&G Bolt Release pad ($120) (undercut the underside of the front to allow to be a lifter for fast unloading) 7) Mesa Tactical Urbino Pistol grip stock with limbsaver butt pad and cheek riser ($170) 8) ATI Raven Forend with heat shield ($110) 9) Taran Tactical Ultimate Reduced Power Trigger Spring ($8) 10 Taran Tactical Ultimate Reduced-Power Buffer Spring (removed; would not always close the bolt) 11)Taran Tactical AccuGuide Extended Carrier ($80) The extended carrier was part of a significant loading port modification. Using a Dremel tool, I ground around the port to make it longer and lower. This is needed for the Load 2 method, where you pull a stack (or double stack) of two shells off of your belt for faster loading. Shown here with a 2 3/4 shell.

Bump. Offers welcome.

The ATI extension is only a plus one (6 shot total).

The ATI forend and heat shield are compatible with the 7 shot tube. However, the Tube Picatinny Rail Shroud will not fit unless you figure out a way to shim the tube. Perhaps you could wrap the tube in a thin sheet of material to build it out to the diameter of the ATI tube. The standard tube has a diameter of 25.33 mm and the Rail Shroud is made to fit the ATI extension tube with a 27.6 mm diameter.

I ordered mine on Jan 8, 2015 and it finally shipped Jun 24. My first followup email was April 3. The next day, Marcy Carrier replied stating it would be another 6 weeks. So, 6 weeks later (May 20) I wrote a second followup. Marcy wrote back, "We completely understand your frustration, and it occurred to me that I was not very specific before. We were hoping for the end of April or beginning of May on this, but have experienced a few setbacks." Details included. I refrained from cancelling my order and, a month later, was happy that I did. Quality is worth the wait.

Buy it all for $100!!! Pulled these parts off of my Benelli M4: 1) ATI Raven Stock - The stock assembly is multi-positional in more than just the standard retractable aspect. It also allows the user to change the comb height with a simple twist of a wheel, which allows for a more comfortable check weld. The stock assembly also has some features specifically designed with comfort in mind, utilizing the ATI Scorpion technology which wraps the pistol grip, comb, and the butt plate in softer rubber. Retail $300, Sell $160 2) Mako Quad Rail Forend - light internal modification to keep gas pistons from touching the forend; pistons function perfectly. I also removed the bottom rail to improve the feel of the grip. Retail $80, Sell $40 3) ATI Raven Mag Tube, +1 tube (with cap, spring and follower) Total retail $78, Sell $40 4) ATI Raven Mag Tube Picatinny Rail Shroud, 3 sided rail. Retail $75, Sell $40 Take it all for $100

I just mounted a Scalarworks rail and Trijicon RMR 07 on my M4. Great set up.
