Owners of the A400 RR Custom Xtreme Plus appreciate the reliable cycling and the quality of the Rob Roberts camo work. The 26-inch barrel is a common preference for upland and field hunting situations where a shorter swing is an advantage.

The soft-operating gas system draws consistent positive feedback, and the 3 1/2-inch chamber capability gives users flexibility with load selection. Some owners note the synthetic stock feels utilitarian but holds up well in wet conditions.

Opinions on the Rob Roberts premium are mixed. Some buyers feel the camo finish and custom touches justify the cost over a standard A400; others would prefer more factory warranty coverage on a custom-built gun.
