Accurate, simple, bulletproof! The Primos Bombshell is the result of 3 years of prototyping, test and tweaking, in order to bring Turkey Hunters the best sounding, most versatile, simple to use Turkey Call we could make! Simply push the rail to automatically yelp, tap the rail to cut, and slowly press the rail to purr or whine. The Bombshell's rail can be adjusted to tune the call for higher or raspier pitch. It can also be locked for quiet carry. In addition to all of this, the Bombshell is designed to be mounted to your shotgun so you can call with very little motion to bring that gobbler in close. Features: Automatically reproduce yelps, cuts and purrs by simply tapping the rail Twist to tune from high pitch to raspy pitch Twist lock for quiet carry Pull cord allows you to operate when attached to your gun
