The M&P Accessories Customizable Lower Parts Kit (brand part no. 110115) provides the minor hardware most AR-15 builds need, from a name backed by Smith & Wesson’s M&P accessories line. It’s built to give builders flexibility: rather than locking in every component, the kit covers the pins, springs, and detents that rarely need upgrading while leaving room to swap in a preferred trigger, safety selector, or grip. That makes it a practical starting point for a first build or a budget-conscious upgrade project.
