LMT L129A1 LM308SS | 7.62×51 | 16″ Barrel

The LMT L129A1 / LM308SS is presented as a semi-automatic AR-pattern rifle chambered in 7.62×51 NATO with a 16″ barrel and a 20-round magazine. It combines an AR-style control set with a heavy-caliber platform intended for extended-range accuracy and duty-style use. For a matched optic under $1,000, consider a Vortex Viper PST Gen II 1-6×24 to cover medium-distance engagements without exceeding the budget.

Typical applications include designated marksman duties and precision target work at intermediate ranges. The rifle ships with flip-up front and rear sights and a polymer stock for reliable field handling.
