Build history on GunPartPicker
Builders on GunPartPicker first added the CMMG AR-15 Hammer Spring to a build in March 2026.
Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today 4 of the 5 retailers we track have it in stock. It dipped to $1.63 at Brownells for a stretch in August 2026, well under its usual $1.86, so sales do come around. Buying today, the lowest price is $1.86 at Brownells, above August's low of $1.63, so a better deal may come back.
