Build history on GunPartPicker
Builders on GunPartPicker first added the LBE Unlimited AR-15/M4 Buffer Tube KIT with H3 Buffer Black to a build in May 2026.
It was hard to find in August 2026, in stock on only 8 of the 23 days we checked, and today only Primary Arms has it in stock. It dipped to $76.99 at Sportsmans Outdoor Superstore for a stretch in August 2026, well under its usual $110, so sales do come around. Buying today, the lowest price is $110 at Primary Arms, above August's low of $76.99, so a better deal may come back.
