This is a “real” AR-22 / AR-15 in 22LR (most are looking-alikes); this is a 22LR BCA upper with thread protector (so that switching to a silencer won’t require a wrench/AR-15 tool).
Lower tuned to work with 22LR via JP enterprises trigger+hammer springs and “bore buddy; center-fire works too (Google bore buddy to see how it works). Spikes tactical with ambi safety and extended magazine release. Also includes 2 Black Dog machine AR-22 magazines (25 rounds IIRC) Magpul furniture, and a sling.
As far as sights go, on the 22LR upper are iron sights (similar to a carry handle and gas block front sight), and on the 223 Wylde upper is a Feotech. Feotech being a fake Feotech; works surprisingly well as long as it isn’t too sunny.
I got the 223 Wylde upper mostly to have a matching pair of right side charging handle uppers. If you don’t want it, that’s fine.
