Video: The Quiet Advantage Of Daniel Defense’s DDM4ISR


Featuring an integrally-suppressed barrel, Daniel Defense's DDM4ISR proves a nimble and quite carbine.

As human nature goes, it’s easy to get caught thinking there’s only one way to skin a cat. When it comes to firearms, perhaps nowhere is this more demonstrable than suppressors. Most get it into their heads the muzzle device must be a separate accessory, something screwed on and off whenever you need to hush up a gun. Logical, given this style of suppressor dominates the market, but blinds us to an entirely different class of noise reduction devices that may prove wholly more useful for some applications.

What we’re aiming at here are integrally suppressed firearms. Certainly, the system might not be for you if you’re after for one can to cover a swath of guns. But if you’re looking for a little something to enhance the capabilities of a tactical carbine, it’s tough to beat an outfit such as Daniel Defense’s DDM4ISR. One gander at the integrally suppressed gun and it’s easy to see why.

In addition to excellent sound suppression, the DDM4ISR maintains highly nimble dimensions. With the suppression system, the 300 BLK’s barrel measures in at 16-inches, which keeps it familiar to any AR user and cat-quick in CQB. You couldn’t ask for better if you were considering a long gun tuned for home defense. Or simply a system that tailored to a ‘T’ for suppression and performance.
