Winchester SX4 tube extension [Ga.12] | +4 rounds

Magazine tube extension for Winchester SX4. Full compatible model list below.

Adds 4 rounds of extra capacity. Extended tube shifts weight forward for improved balance under recoil.

• Extended capacity keeps you shooting through longer stage runs or sustained strings without reloading.
• Forward tube weight shifts the balance point ahead of the action, steadying the shotgun under recoil for faster follow-ups.
• Precision-machined extension maintains reliable feeding at full cycling speed.
