When I learned that Howa was going to start making their Mini actions with the Grendel/7.62x39 boltface, I was really pleased. It opened up the use of these fine little actions for so many interesting chamberings - 6PPC, 6RAT, 20 Grendel, 22 Grendel....etc, etc., plus the 6.5 Grendel, which is no slouch itself. First issue was finding aftermarket stocks for the Mini, then a replacement for the flimsy plastic triggerguard/mag well units that they ship with....and once suppliers stepped up to bringing out a good selection of stocks and/or chassis and machined aluminum DBM units, I was very pleased. I personally haven't had many problems with the plastic OEM magazines, aside from having to deepen the bottom inlet for the DBM on a couple of stocks to put the magazine high enough to feed properly. To date, I've built myself four custom rifles on Mini actions, ranging from a 20 Tactical to a 6.5 Grendel, and I've gotten a lot of satisfaction & enjoyment out of them. LSI isn't the most organized outfit to deal with, but I've been able to get most of that I needed from them, including several barreled actions before they granted Brownells exclusive rights to sell them.
However, I kind of doubt that we're going to see a really good replacement magazine out of them - that's just my opinion after dealing with several different people who work at LSI. Some of them are apparently not gun people, based on my experience. If anyone has contacts in the industry who are willing to listen to owners' issues with the OEM plastic mags, I'd certainly encourage you to work diligently to try to enlighten them where the need for better mags are concerned. I believe good magazines would go a long way towards making these little rifles a whole lot more appealing.
