Remanufactured 300 Blackout Subsonic 220gr Spire Point. Although these cycle in multiple barrels, This round performs best subsonic out of a 1:7 twist rate. Due to the tight tolerances of new rifles chambered in 300 BLK, we suggest that brand new firearms be broken in with factory new ammo. A firearm that has been properly broken in, will guarantee proper chambering and cycling of any remanufactured ammunition. Also with any new upper ensure your gas rings are adjusted correctly. Not all manufacturers adjust the weapon from the factory. If not properly adjusted some rounds will not cycle.

***PLEASE NOTICE LEAD TIMES ON ALL NEW ORDERS LISTED ON THE HOMEPAGE. THE UPS ETA DURING CHECKOUT DOES NOT INCLUDE THESE LEAD TIMES. THANK YOU***
