Thread: Ultimate compact rifle & catrige - 6mmGT/22GT in howa mini action

Both are used in AR, a platform known weaker than a bolt action. the mini certainly will be weaker than a standard action but by how much is anyone's guess. Again you have very good point there. As for magazine, if it can deal with 450 bushmaster then it should work on GT. I have a 3d printed mini magazine so it is not end of the world if the factory one doesn't work.

Nice i have been trying to find the STL for those for a while.
