Budget?
If you want to spend White Oak money, you are barking up the right tree.
Just watch the weight.
If the 18" fit my weight, I'd give it a cap for the threads.
Keep it short. Or a deflector if you want.
Probably assemble the lower.
Assuming you don't mind spending a bit.
Good stock and trigger of your choice.
However,
I concur...
Cheap and effective...
Down the road you can upgrade to a WO (or whatever) if the PSA disappoints...
IMHO... the PSA will shoot just fine.
As before.
The PSA will un-alive coyotes at 250yds.
But if you doubt it, every miss will be blamed on it. (Even though the truth...😁)
You gotta trust the equipment.
