Build history on GunPartPicker
Builders on GunPartPicker first added the CMMG Buffer Assembly Carbine MK10 8oz to a build in September 2026.
It was hard to find in August 2026, in stock on only 6 of the 12 days we checked, and today only CMMG has it in stock. Prices barely moved in August 2026, holding around $169.99, so there haven't been real sales lately. Buying today, the lowest price is $199.95 at CMMG, above August's low of $169.99, so a better deal may come back.
