At CMMG we strive to provide the best products and customer service we can.  If you have any questions regarding your product or you believe your product is defective, please contact technical support at techsupport@cmmginc.com or 660-248-2293 ext 2.  All CMMG products feature our Lifetime Quality Guarantee

CMMG Lifetime Quality Guarantee
CMMG, Inc. will guarantee its products against defects in material or workmanship. CMMG, Inc. will repair, replace or substitute part(s) (at CMMG, Inc. discretion) at no charge to the customer if a defect of material or workmanship is found. All service work must be carried out by CMMG Inc. Please provide a copy of the invoice or proof of purchase when submitting service work.

Notice(s)
CMMG, Inc. sells complete firearms and components. If you have received a CMMG, Inc. firearm and are not satisfied, please contact CMMG, Inc. If you suspect your firearm isn’t factory built, contact CMMG, Inc. for confirmation.

Returned products that are found without a defect are subject to a 15% restocking fee.

All CMMG firearms are designed to function with a wide variety of ammunition and undergo rigorous testing prior to release to ensure reliability and durability. Not ALL factory loaded ammunitions are compatible with CMMG firearms, and not all CMMG firearms are designed to function with factory loaded ammunitions.  Atmospheric conditions including, but not limited, cold, heat, high humidity, and high altitudes may affect the operation and functionality of CMMG firearms, including, but not limited, cycling, ejection, and extraction.  Because CMMG relies on select types of ammunition for testing each firearm and upper receiver group before shipment, we cannot guarantee reliable function with all types of factory loaded ammunition, handloads, or reloads. Lifetime Quality Guarantee claims due to ammunition selection will be subject to review by CMMG Tech Support staff and coverage will be determined in CMMG sole and absolute discretion. CMMG recommends testing small quantities of your preferred ammunition for operation and reliability prior to committing to using only one type or brand exclusively.  CMMG, Inc. makes no claims that all ammunition brands, bullet types, or power factors will function without issue in our firearms.

 

Note: Some ammunition is designed to run within certain parameters (i.e.: subsonic, “low recoil”, “hush”, etc.) and are not designed to function within the configuration of our firearms.  Choosing to use those types of ammunition will require the end user to purchase aftermarket solutions to aid in the operation of our firearms. Aftermarket solutions are at the expense of the owner and include, but are not limited, buffers of different weight, sound suppressors, adjustable gas blocks, and CMMG’s Action Tuning Kit.
