Sig Sauer just released a Rattler version of the new MCX Spear LT. The new Rattler-LT will ship as a non-braced pistol or SBR.
This new variant will have a 6.75” BBL in 300BLK to match the LVAW contract rifle built for US-SOCOM. The 7.62x39 option will be equipped with a 7.75" barrel. All Rattler-LTs will have the option to be suppressed and will ship with the SIG SL flashhider pre-installed.
A 5.56mm Rattler-LT has not been announced and we are unsure if one will be produced.
