8.6 Blackout 300gr Rex Subsonic Expander


If there’s no “In Stock” quantity displayed, then this offering can be backordered. Backorders can take 7-10 working days until they ship out. These particular projectiles are made in small batch runs from 2k to 5k per run.

In stock quantity only reflects that there are enough components in inventory to fulfill the displayed in stock quantity. Typically, subsonic ammo is not a “one size fits all” proposition and is made to order due to specific barrel length requirements. Due to high demand, allow up to 3 days for in stock orders to be fulfilled and shipped out.
