I’m considering having a spare 20” 5.56 barrel converted to an LMT barrel extension for my MRP upper. My LMT is an 11.5” SBR topped with a NF 1-8 ATACR.
I think it would be sweet to swap barrels and stretch it out to further distances with the 20” barrel. I’m curious what your experience is with the POI between barrels. Example: zero optic to 11.5” barrel, swap in 20” barrel, mark turret for 20” barrel zero then swap back to 11.5 and original zero. If I would have to adjust the zero each time I swap barrels, then I’d rather not do it.
