The Quad-Lock™ from MegaMouth® Bowfishing is the ultimate 4-barb point when it comes to lock-down, power grabbing performance. Two shorter, quick engage barbs lock in with 2” of holding power. They are complimented by two longer barbs that lock in with 2.5” of holding power. The short body and four collapsing barbs make an exceptionally small entry hole on the shot and offer maximum penetration. Just turn the arrow shaft a few turns when the point is engaged, and the barbs will release.
