I was intending to do this, but it isn't necessary as the magazine well and release is attached to the bottom of the action, so an AICS stock will fit straight on, the issue is the magazine hits the trigger guard before seating. The only work around would be to remove the magazine well and have a custom made AICS sized magazine that works in the T1x, not a simple endevour I'd imagine.
I’m thinking I may run into this issue with my MPA Chassis next week. When extra magazines become available perhaps they can be modified to cut off the lower “half” and shorten the spring or perhaps the “bulge” could be removed. It would of course result in lower capacity but might be a workaround until someone comes up with a better solution.
