Thanks for the compliment.
For any civilian a piston AR with NP3, like my POF, is overkill. I did it simply because I'd rather have the rifle then the money. It's a favorite toy.
My son-in-law tells me that they used the .458 or .50 cal to stop cars that tried to run checkpoints and access gates. The .223 were totally ineffective and .458 was very effective.
