Arms Precision Inc: 2.0 TCR = 62% of Machine shops BLS 3.3 · 2y Form 300A (see methodology below)

Arms Precision Inc safety composite

Arms Precision Inc scores strongest on dart rate (safer than 75% of same-industry peers) and weakest on fatalities (safer than 50%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
