VFC Version 2 ECS Avalon Gearbox Shell w/ Quick Change Spring

"Solid well made gearbox.
Built about 4 dsg's and all held up perfectly fine.

Best budget gearbox aside from lonex. 👍

"ive had this for about a year now in my vfc scar, works great. the spring guide broke on me though, one of the arms on it broke off and unfortunately you have to buy the vfc spring guide. i tried finding other qsc guides to fit and none of them worked. i bought my replacement on mir tactical for 24 bucks so its pretty expensive but thats what happens when you have vfc specific parts.
