New to this thread, but definitely not to the Mini platform.
I fell in love with them when they were first teased years ago and promised myself I'd buy one if they ever chambered it in Grendel.
Instead, I picked up a 6 ARC Mini about three years ago, and it exceeded every expectation.
Since then it's evolved quite a bit, and I recently picked up a second one as a dedicated experiment. I'd still love to find a stainless barreled action.
Right now I'm prototyping a steel magazine system that's essentially a hybrid of the CZ 527 and AICS, paired with matching aluminum bottom metal. The bottom metal is a scaled-down Atlasworxs design, but with the mag release integrated into the trigger guard instead of hanging below the front of it.
Once my action gets back from LRI, it'll wear a 17" 6mm 1:7 PBB Taperless (.810) barrel w/ their helical fluting. Then I'll start final testing to see if the new bottom metal and magazine provide enough room (~2.65" internal length) to feed a 6 GT. If not, it'll become a long-throated Dasher, and I won't complain.
