The Benelli M4 EXT draws owners who want a premium gas-operated tactical shotgun with an adjustable stock. The telescoping stock on the EXT variant is a frequent topic: most find it a practical upgrade over the fixed stock found on standard M4 configurations, particularly for shooters who share the gun or use it with body armor.

The MultiCam Black finish gets strong approval from those who prioritize a low-visibility tactical look. Build quality comments are consistently positive, in line with expectations for the M4 platform. Some owners note the tube capacity is identical to the standard M4 and wish the EXT designation included a magazine extension.

The M4 EXT sits at a premium price point, and most buyers accept the cost as consistent with Benelli quality. The occasional complaint centers on finding a holster or case that accommodates the telescoping stock in its collapsed position.
