Wilson Combat’s SBR Tactical is extremely powerful yet easy to maneuver with in close quarters. Wilson’s proprietary 7.62×40 WT cartridge has just the right amount of knockdown power to pair with the SBR’s barrel. This is truly a versatile platform. Shown here with an Aimpoint CompM3.

New chamberings come and go all the time, and this has always been the nature of the business. Someone is always trying to improve on existing cartridges, platforms and systems. It is this innovation that makes the firearms industry as strong as it is.

One of the longest standing of these projects has been the short .30 caliber for the AR platform. Since the first time a U.S. soldier fought against the AK-47 and its 7.62x39mm cartridge, the industry has tried to make that round (or one like it) work in an AR. It is a project that continues to this day, resulting in cartridges like the 300 AAC Blackout, .300 Whisper and a few others. They are all an attempt to approximate the ballistics of the 7.62x39mm and function properly in an AR-type rifle. For most, that is as close to 2,400 feet per second (fps) as you can get with a 125-grain bullet. New powders, bullets and precise manufacturing have made this better with each passing year. But getting these cartridges to fire has never really been the issue—it has been getting them to work in magazines.

The Wilson Combat Whisper762 suppressor does little to affect the balance of the SBR Tactical—it’s lightweight, quiet, and reliable. During range tests, the suppressor showed no signs of shifting the point of impact. It provided minimal backpressure, never came loose, and maintained excellent sound suppression.

Take a close look at an AK-47 magazine. It curves almost immediately. Other than the lip of the magazine, about an inch or so, it is one continuous curve. This is necessary for the ammunition to feed properly past about ten rounds, given the cartridge diameter. You could make a straight magazine, of course, but it would be too long to be practical, and still presents its own set of issues. You need the curve in order to make it practical with a 30-round magazine—even for a 20- or 25-rounder. Without this curve, the rounds will bunch up in the middle and cause malfunctions. It is just one of those laws of physics that cannot be circumvented.

Wilson builds their SBR with their TTU (Tactical Trigger Unit), which provides operators with a clean two-stage trigger.
