I didn't realize there was a change to the barrel channel in 2019 which dropped the max recommended barrel contour from MTU down to M24. I'm waiting to hear back from MPA about it but in the meantime I thought I'd ask here as I'm sure many have experience with this. I have 2 MTU barrels on order, one for my 2017 MPA BA comp and one for a buddy's currently on order MPA BA comp chassis. Where is it that the clearance would be an issue? Is it the NV bridge and possibly the ribs under the barrel only, or is there not enough room for a 1.250" shank in the chassis either? We both wanted to run a 1.250" shank with a straight taper, but I'd like to know if that's even possible or if I need to change my barrel order to an M24. Any help would be appreciated!
