How about a 50 caliber upper for your AR lower?  It’s not really a new idea, but the folks at Safety Harbor Firearms do as nice a job as anyone at this.

They offer both single shot and magazine fed bolt action conversion uppers for AR lowers.  It does require a hammer and spring replacement available from their web site.  Complete rifles are available as well.  These are all in what I would call carbine configuration with barrels in 18″, 22″ and 29″.  I suppose the AR lower limits the amount of weight that can be put out front, so barrel length is relatively short for a 50.

Prices for an upper alone start at around $1450 so it is very cost effective if you want to own a 50. With new restrictions on the radar being able to reuse your lower on some other gun may be an important option in the future.
