Just recieved my foundation stock with hawkins bottom metal and i am having a little issue when using ARC aics magazines. It feels like they fit really tight in the magwell, and i have to slam the magazine up hard so it will actually latch. When i try to use the mag release i can barely push it forward, feels like its binding up. However whenever i use my 10 round accurate mag everything functions flawlessly. Any ideas? I cant use the accurate mag as it is a .223 mag. And the rifle is chambered in 6.5 manbun.
