October 2026 on GunPartPicker
LMT AR-15 Buffer KIT - Mil-Spec was the fifth most added buffer on GunPartPicker in October 2026, behind the Spike's Tactical Spikes Tactical T2 Tungsten Buffer, Black - SLA00T2, with about 6% of all buffers added to builds. Up from #8 in September. Builds with this buffer are nearly all chambered in 5.56 NATO, mostly on mid-length gas (90%, then carbine-length 11%), and nearly all AR-15.
It was in stock most times we checked in October 2026, and today both retailers we track have it in stock. Prices barely moved in October 2026, holding around $90, with no real sale all month. Buying today, the lowest price is $90 at Primary Arms, which matches the best price we saw in October.
