Careful assembly is key for any airsoft gun owner! Ensure you've got the expertise or get a trusted pro to help. With regular maintenance and useful advice from an experienced technician, your weapon will be in tip-top condition. Don't forget: strong screw glue should always be used when installing parts - it'll keep those screws secure overnight, preventing damage down the line. Jefe's Airsoft Solutions offers a complimentary installation service when upgrades are purchased with any AAP-01!  Interested in our mail-in service?
