Personally I like the AR platform, as others have said the S&W is hard to beat value wise, reliable and OK accuracy for their intended purpose.
After the demise of Mr Bradley I had a rifle built but Keystone Accuracy in the US who also cuts the chamber and extractor slots into the barrel, I free issued a 2 groove Benchmark blank to him as I wanted a bit more weight up front to balance the (heavy) Magoul stock.
Very reliable and accurate rifle
50m results with various ammo types, shot in a cadence not BR style, feeds well using S&W magazines with the spaced pad, locks open on last round consistently.
