Howa Mini Rifles, Builds, and Upgrades

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.
My first Howa has already gone full wildcat — a cartridge I designed with Dave Kiff at PTG. I call it the 350 Smilodon. It's essentially a +P, short-neck 358 Winchester pushing 140gr Stone Hammers at 3,100 fps from a 18.5" barrel.
That rifle now sits in a Stocky's CF Hunter stock with an LRI-fluted bolt, Oregunsmithing hinged floorplate, Jard trigger set to 6 oz, Talley LW 30mm rings, Tract bubble level, and a Trijicon Credo 2-10×36 FFP with AADMOUNT lens caps. I also made the leather/spandex butt cuff myself because I couldn't find one that fit what I wanted.
Really glad I found this thread.

Will these mags and bottom metal be commercially available? That’s what I have been waiting for is a mag system to do a 6 Dasher.
 
Stocky makes these for the Howa OEM rifles, so I assume they are making a ton of volume and stockys sells all the seconds throwaways on their website
Only for one premium model (Carbon Stalker with steel barrel) and one super premium model (Carbon Elevate with CF barrel). Carbon Stalker has 6 Mini Action cartridges and Carbon Elevate has 1 Mini Action Cartridge. All other CF models have been swapped to HS Precision stocks as their factory offering. I've never seen any of those model rifles (in a mini action) in a gun shop in person. Everyone has to order it if they can or you have to buy it from Gunbroker. If Stockys makes 2000 CF stocks for those specific models plus 400 for their own inventory that's 2400 stocks. If ~200 are blems, that is an 8.3% failure rate if zero failures are trashed.

Regardless, almost 200 being sold as blems is crazy, to me. If Stockys is that busy, it is another potential reason why the RS and RS Lite are slow to market.

I ended up moving forward with the 22arc build, with the HB barreled action through brownells. I might end up chopping the barrel down, but figure I’ll try it out first at 20”.
 
If/when get it figured out, absolutely! 💯

You figure out a bottom metal mag situation for minis that allow 2.5” coal loading and feeding, you’ll sell a pile in this thread. Shoot me a PM if you want, I have some work done on the hinged metal side I can share with you that might help what you’re doing. I’m too busy to mess with it
