The whole, "the military uses it, so we should too!" doesn't work in almost every circumstance.
No offense, but:
Ever hear of 1911? How about Glock? Beretta? Sig Sauer? H&K? All these companies market products that were directly developed for the military? They seem to work pretty well...
Do you have a flash suppressor on your AR? How about the AR itself?
Lots and lots of military technology is directly involved in our guns and accessories and it works.... That's not to say every military device is appropriate but much of it is..
