M79 Grenade Launcher – “Blooper”

Highly Detailed & Realistic 3D Printable Prop

“Hasta la vista, baby.”

An unmistakable symbol of the Vietnam War and a true movie legend.
The M79 “Blooper” is instantly recognizable — simple, brutal, and unforgettable.

This model is a highly detailed, non-functional prop, created specifically for display, video and photo shoots, cosplay, LARP, and private collections.
The focus is on visual realism, durability, and long-term reliability, not unnecessary mechanical complexity.
