Stupid Airsoft does two external upgrades for the Action Army AAC-C1 airsoft sniper rifle: a quick pull bolt handle and a thickened butt plate. He first details the installation of the new quick pull bolt handle, which requires partially disassembling the bolt to attach the component and give the rifle a modern, speedsoft aesthetic.

He then installs the thickened butt plate, a simpler cosmetic and ergonomic upgrade designed to be more comfortable on the shoulder. From there, he concludes by expressing his satisfaction with both parts as valuable steps for customizing and enhancing the AAC-C1 replica.
