Most people associate Wilson Combat with the 1911 platform. While it is true that Wilson Combat makes some of the best 1911s on the market, it’s also true that they make some of the best AR-15s on the market as well. The SBR Tactical is essentially Wilson Combat’s PDW version of the AR-15. The Wilson Combat SBR Tactical comes with a standard barrel length of eleven inches with an overall weight of twenty eight inches. The total weight is just six and a half pounds. But perhaps the real standout is the fact that it is available in four different calibers: .300 HAM’R, .300 Blackout, 6.8 SPC, and 5.56x45mm NATO.
