Developed for beginner, intermediate and advanced shooters, Altered Environments shotgun is designed to give students an understanding for increasing; mental sharpness, focus, and skill in performing handgun operations.


Before signing up for any Mantis Global courses you must verify that you are legally and physically able to attend our courses. Our courses require that students are comfortable with shooting near other students. Must be capable of movements that include: kneeling, prone, and maneuvering around obstacles. You will not receive a refund if you attend a class and do not meet these requirements.

NOTE: If you have been arrested for any violent act or felony crime you need not register.  If you are unable to carry or otherwise legally possess a firearm, you need not apply. we reserve the right to conduct a background check on you and refuse service to anyone

NOTE: Your registration is not complete until we have received your full payment. If you chose to pay by credit card, your position is guaranteed because you have paid the entire tuition up front. Your tuitions are not refundable, nor are they transferable from class to class. Positions in these classes are limited, therefore, if you are unable to attend, it will be your responsibility to find someone to replace you. On the other hand, we understand sometimes things happen that are out of your control, so, if you give us enough time to fill your slot, we will allow you one courtesy reschedule (provided that your reason for having to miss is valid).
