Vrooom Armament conducts an in-depth performance review of a custom-built Tokyo Marui VSR One rifle. They do various tests, including accuracy and range tests at distances up to 300 feet, and a chrono test indoors for consistency. They are impressed with its compact size, impressive range, and consistency, and suggests it is an ideal backup rifle for longer events.
Vrooom Armament shows how to modify a Tokyo Marui VSR One chassis to add a Maple Leaf mag holder, which is not originally fully compatible. The process involves drilling a second hole in the mag holder for increased stability, ensuring it aligns with the M-LOK rail section on the chassis. The most crucial step is to dremel a cutout on the VSR One chassis to create a flat surface that allows the mag holder to sit properly and accommodate a magazine without interference.
