Who owns a CZ MTR,or an RAP?

[TNBear731]

I have the RAP in the the Magpul American stock and have tried a lot of different magazines. Ruger 223 AICS magazines did not work, the magazine will not even fit in the magazine well. Old school polymer AICS magazines are close, but didn't work. The rounds wit too low and the bolt just glides over the top. The MDT 223 magazines have the same problem as the older AICS magazines. The only magazine I have that works reliably is a 5 round 308 metal AICS magazine with the 6br insert. You have to run the bolt fast, but it works.
