Prvi Partizan 300 BLK 125gr FMJ 20rd Box

This Prvi Partizan 300 Blackout load uses a 125gr full metal jacket bullet, a supersonic weight for AR-15 rifles and pistols. It is a practical round for practice, drills and plinking with a 300 BLK upper.

Each box holds 20rd. It is not a subsonic load, so expect the normal crack even behind a suppressor. The 300 BLK case fits standard AR-15 magazines and bolts, so only the barrel changes from a 5.56 build.
