So 16" and shorter barrels made are generally not designed for 1/2" accuracy. That doesn't mean the length of the barrel has anything to do with it. It's the construction and materials of the barrel that make them less accurate.
But sub-MOA garantees are dime-a-dozen. RRA has a 3/4" garantee on 16" several models, for example.
stag arms guarentees 1/2 moa on at least one of there 24" models and 3 of my 16s are wylde chambers ss barrels
