What are the chances? First the Ruger-57 and now the Diamondback DBX. Two new 5.7x28mm guns that nobody saw coming. And they’re both great! In the video above, Diamondback gave us the run-through of the DBX and then we put a few rounds downrange.
And it was great!
The DBX is sort of like a miniaturized AR-style gun. In fact, it accepts standard AR triggers, safeties, and grips. A Picatinny rail on the rear is ready to accept pistol braces like the SB Tactical FS1913 seen in these photos, or a shoulder stock like the about-to-be-released Black Collar Arms Stock Option.
The DBX is gas piston driven, with two pistons acting on the bolt to set it in motion rearwards at the right time. This is different from other 5.7x28mm firearms on the market, most of which are using some sort of delayed blowback mechanism. It shot smooth and soft, as you’d expect.
FN Five-seveN magazines (or ProMag aftermarket versions) are used in the DBX. It has a reciprocating charging handle that can be quickly and easily switched from left to right side.
One of the best “features” of the DBX is its weight: about 3 lbs without the brace and 3.7 lbs with it. It feels incredibly lightweight and maneuverable. This would make for a fantastic critter hunting gun, whether it’s for prairie dogs or gators.
Diamondback will begin shipping the DBX on 5/7/2020 and MSRP is $1,299.
Our initial impressions of the DBX’s machining, fit, and finish are very high. It looks and feels like a well-made gun, and though we only shot a few rounds through it it seemed well-sorted and ready to rock.
The Diamondback DBX 5.7×28 was one of the coolest and most interesting new releases at Range Day. We don’t know what’s up with this sudden 5.7 interest, but the rumor around town is that a few ammo manufacturers are circling back to the cartridge and looking to put out some more ammo options and some more affordable ammo options. If that happens, there are some new guns in my future.
Obviously TTAG will work to get our hands on a DBX as soon as we can for a full review. Please send ammo.
