Based off the Fair Deal Magazines by General Custer (great work). Will be compatible with Black Dog Machine springs as well as the OEM Z-springs. Two sets of followers for each spring type. Z-springs can also be found on AliExpress and I will provide the dimensions on release.
Thanks man. For longer barrel lengths you’ll definitely need some tungsten. My 16" build has the weight up to 1.7 oz. and it still doesn’t run 100%. Also, lubricate generously.
Greatly appreciate it brother
