CMMG Mk4 price data FAQ
What is the average price of a used CMMG Mk4?
The average asked price for a used CMMG Mk4 is $800. GunList found 4 active or historical pre-owned listings; customized, collectible, trade-only, accessory-heavy, and unusually priced listings are filtered before the median is calculated. Because fewer than five current priced listings are available, archived and sold listings are included. Pricing data was last updated in October 2026.
What is the average price of a new CMMG Mk4?
There are not currently enough new CMMG Mk4 listings to calculate a reliable average asking price. New-in-box condition, generation, and factory configuration can also affect the price.
What price should I list a CMMG Mk4 for?
Based on the filtered used CMMG Mk4 median, consider $640 to attract buyers faster, $800 for a balanced asking price, or $1,000 if you are willing to wait. These options are 20% below, equal to, and 25% above the filtered market median. Because fewer than five current priced listings are available, archived and sold listings are included.
What is the current used CMMG Mk4 price range?
Comparable used CMMG Mk4 asking prices range from $800 to $1,000 after customized, collectible, trade-only, and statistical outliers are filtered. Accessory-heavy listings are also removed when enough comparable data remains. Because fewer than five current priced listings are available, archived and sold listings are included.
How is the CMMG Mk4 value calculated?
GunList analyzes marketplace listings explicitly linked to the CMMG Mk4. When fewer than five current priced listings are available, archived and sold listings are also included. Zero-price, customized, collectible, and trade-only listings are excluded. Accessory-heavy bundles are removed when enough comparable listings remain, then unusually low and high prices are filtered. The reported used value is the median asking price, not a completed-sale price or formal appraisal.
Does the CMMG Mk4 value vary by state?
Yes. Among states with CMMG Mk4 data, average asking prices range from $800 in Missouri to $1,000 in Idaho. Availability, local demand, and small sample sizes can cause regional differences. Because fewer than five current priced listings are available, archived and sold listings are included.
Why might my CMMG Mk4 be worth more or less?
A CMMG Mk4's value can change with condition, generation, finish, round count, factory configuration, modifications, included optics or magazines, original box and paperwork, provenance, and local demand. Customized or accessory-heavy examples may sell outside the comparable price range shown here.
