Tuning Bottom metal with Brownell's 10 and Tikka 223

[richidaho]

Looking for some guidance on tuning Atlasworkxs AICS bottom metal; with Brownell's 223 10 round mag, Boyd's At-one stock, and Tikka T3 223 varment action. At the current time, the mag will feed but I have to wiggle the mag around in the back to allow the mag to feed. Any pointers would be helpful.

Thanks
