In the realm of films, firearm props are a common item in productions used to create action. Normally, the real physics of gunshots are added in post production via video effects. This can be time consuming and tedious for the editor, so some directors choose to do effects practically to minimize strain and time in production. For independent filmmakers, however, both practical or virtual effects can be either too costly to acquire (especially in bulk), or cheap but low-quality.
A suitable medium for this dilemma would be an affordably-priced prop firearm attachment that realistically mimics muzzle flash.
Design and fabricate an adjustable muzzle flash simulation unit attachment for independent film prop firearms with variable intensity. It will be adjustable at the tail end to allow for compatibility between firearm models with muzzles of different diameters, and have variable intensity to suit individual preferences.
