Walter Keller from Safety Harbor Firearms provides expert guidance on selecting and installing the KES MP5 Collapsible Stock. The video emphasizes the critical difference between 1-pin (full-size) and 2-pin (K-model) MP5 receivers, which dictates stock compatibility. It also details how manufacturing tolerances in sheet metal receivers can affect fitment, with a preference for a snug, wobble-free installation, even if it causes minor finish wear.
