Best Benelli M4 Follower
Why the Max Room Follower Is the Top Upgrade
For Benelli M4 owners looking to increase magazine capacity with longer, roll crimped rounds, and add a 922(r) compliance part, the Max Room follower stands out as the most effective and purpose-built option. While many aftermarket followers exist, none address the core limitations of the factory part as directly as the Max Room design.
Below is a detailed breakdown of why the Benelli M4 Max Room Follower is the best overall follower upgrade for the Benelli M4.
What Makes a Great Benelli M4 Follower?
A high-performance follower should accomplish three things:
- An equal or greater feeding reliability as the OEM follower
- The use of high-quality materials, machining, and finishing.
- Optimize internal space in the magazine tube
Most aftermarket options improve durability, but very few reclaim usable space inside the tube—a key factor for shooters trying to consistently fit seven 2¾" shells, especially with longer crimps (defensive rounds and roll crimped rounds). Some followers actually reduce precious space in the magazine tube.
For example, GG&G produces many high-quality firearm parts, but their Benelli M4 follower uses a generic design that isn’t optimized for the M4. Although it appears to increase magazine tube space because of its shorter length, it actually reduces internal room compared to the OEM follower.
This is exactly where the Max Room follower excels.

Why the Max Room Follower Is the Best Benelli M4 Follower
1. Maximizes Magazine Tube Capacity
The defining benefit of the Max Room follower is its ability to add up to 3/16th of an inch of usable magazine tube space compared to the OEM follower.
This extra internal room significantly increases the likelihood of loading:
- Seven 2¾" shells, even those with deep or inconsistent crimps
- Certain defensive loads that are slightly longer than standard
- Roll crimped rounds that have a longer crimp length than fold crimp rounds
If your setup includes an aftermarket 7-round magazine tube, the Max Room follower is one of the most important add-ons to ensure you actually achieve full capacity.
2. Improved Cycling Through Flat-Face Geometry
The follower uses a refined flat-face design, which reduces friction and improves the consistency of feeding under recoil. This profile gives the Benelli M4 a smoother loading stroke compared to the OEM curved design.
The OEM design has a small ramp on the face of the follower, and if the shell isn’t ejected back far enough into the loading gate from the magazine tube, the crimp of the shell can get caught up on this ramp.
3. USA-Made 922(r) Compliant Part
The follower is CNC machined in the United States, and the front face includes a “USA” engraving. This serves two purposes:
- Counts as one low-cost 922(r) compliance part
- Allows shooters to confirm an empty magazine tube by touch
For anyone building a compliant Benelli M4 with U.S. made components, the Max Room follower is an easy and inexpensive checkbox.
4. Precision CNC Machining and Hard-Anodized Finish
Crafted from 6061-T6 aluminum, the follower is machined to tight tolerances and finished with a hard-anodized coating that is roughly three times harder than the aluminum itself.
Advantages include:
- Long-term resistance to wear
- Smooth cycling over thousands of rounds
- Protection from corrosion and debris
- Multiple color options for easy identification
5. Compact Dimensions and Lower Weight
Compared to the OEM part, the Max Room follower is both shorter and lighter:
- Diameter: 0.9"
- Length: 0.87"
- Weight: 0.17 oz (5 g)
This reduction in length—without compromising strength—is partially what allows the additional internal tube space that makes the Max Room design so effective.
6. Compatibility With Most Benelli M4 Clones
The follower is designed to fit:
- Factory Benelli M4 (Designed specifically for the Benelli M4)
- Most M4 clones
- Aftermarket 7-round tubes
- OEM 7-round tubes and 2-round extension tubes
Conclusion: The Max Room Follower Is the Best Benelli M4 Follower Available
If your goal is to improve capacity or 922(r) compliance, the Benelli M4 Max Room Follower is the most complete, performance-driven solution available. Its optimized geometry, additional magazine space, CNC machining, and robust finish make it a superior upgrade over other aftermarket followers.
For shooters who want the Benelli M4 to perform at its highest potential—duty, competition, or defensive use—the Max Room follower is the clear top choice.
