Overview
The DPMS LR-308 is an AR-10-pattern semi-automatic rifle chambered in .308 Winchester/7.62x51mm NATO, introduced by DPMS Panther Arms in the early 2000s. Built around a direct gas impingement system, a forged 7075 aluminum flat-top receiver set, and a heavy stainless bull barrel, it was one of the first affordable mass-market .308 AR rifles and helped popularize the large-frame AR for civilian long-range and hunting use. Its receiver footprint, distinct from Armalite's original AR-10, became a de facto industry standard often called the 'DPMS/SR-25 high pattern.'

Notes
The LR-308 receiver/magazine geometry (the 'DPMS Gen 1' or 'high' pattern) became one of the two dominant .308 AR standards alongside the Armalite AR-10 pattern. Numerous barrel-length and stock configurations were offered.
Background
The LR-308's receiver dimensions were so widely copied that the entire family of .308 AR rifles is split into 'DPMS-pattern' and 'Armalite-pattern' camps, a divide that still dictates magazine and parts compatibility today.
