They've said repeatedly that it's on the table, but catching up with production demand has been the priority. They're getting close to meeting that goal, so maybe some time next year?
Last i heard they had no plans to do a lefty period, chassis are plentyful so nothing new there.
Now had they released a modified bolt and bullpup for a drop in 700 kinda deal then thats a home run, but another chassis in a market plentiful with them?
