Owners of the EGX500 are drawn to the bullpup layout, which delivers a short overall package while keeping an 18.5-inch barrel in the legal range. The 12 GA chambering and semi-automatic action make it a versatile choice for home defense and range use. The detachable magazine format differentiates it from tube-fed alternatives.

Reliability is a recurring discussion point. Owners report the EGX500 runs well with standard loads once broken in, but some find it finicky with lighter loads until the action loosens up. The synthetic handguard and black finish get practical marks for durability and maintenance.

At its price point, the EGX500 competes against a small field of semi-automatic bullpup shotguns. Buyers who prioritize the compact form factor find it a reasonable value. Those coming from established American or Turkish semi-auto brands note differences in trigger quality and overall polish, which splits opinions on whether the bullpup premium is worth it.
