Specifications
October 2026 so far on GunPartPicker
LMT MARS-LS PDW Complete Ambidextrous AR-15 Lower Receiver ranks #13 of the 520 lower receivers builders have added on GunPartPicker so far in October 2026, behind the PSA GEN3 PA10 Forged Complete MOE EPT SBA4 .308 Lower With Over Molded Grip, with about 1% of all lower receivers added to builds. Down from #9 in September. Builds with this lower receiver are mostly chambered in 5.56 NATO (80%, then .223 Wylde 9%), split between mid-length (51%) and carbine-length (35%) gas systems, and nearly all AR-15.
Availability is good: it was in stock at one retailer or another nearly every day in September 2026, and today 2 of the 3 retailers we track have it in stock. Prices barely moved in September 2026, holding around $1,019.70, so there haven't been real sales lately. Buying today, the lowest price is $990 at BattleHawk Armory, which matches the best price we saw in September.
