Build history on GunPartPicker
Builders on GunPartPicker first added the Luth-AR AR-15 Rifle Buffer Spring to a build in February 2026.
Availability is good: it was in stock at one retailer or another nearly every day in September 2026, but today only AT3 Tactical has it in stock. It dipped to $4.22 at KY Gun Company for a stretch in September 2026, under its usual $4.50, so sales do come around. Buying today, the lowest price is $4.50 at AT3 Tactical, above September's low of $4.22, so a better deal may come back.
