DRD Tactical P556 5.56m AR-15 Upper With Quick-Detach Barrel

P556 Uppers

DRD Tactical, the company that bought us the innovate stealthy Paratus-16, have now developed an AR-15 upper receiver that uses the same quick change/detach barrel and handguard system as the Paratus-16. The rail/handguard unit can be quickly detached from the upper receiver, decreasing the space required to store the rifle. DRD Tactical is also selling a hard case with pre-cut high density foam …

    Looks interesting from an engineering perspective, but currently switching the whole upper isn’t really all that hard. The only real advantage I see is not having to swap optics between uppers, but I guess with the price of some optics that might be enough. Also, sig might not be terribly happy with their choice of names, as sig already makes a 5.56 rifle called the P556.

    Now if they just need a 5.56 version of the Paratus lower (including dat folding stock) to go with it…

    So they made a “more” take-down AR. As with all take-down rifles, I question the mechanical accuracy after detaching/attaching the barrel. I’ve had issues with that in the past on several rifles, especially those where the optics are mounted on the receiver and not the barrel(like most take-downs). This was solved, IMO, by a fully detachable receiver/barrel component such as the AR upper. This mod saves you about eight inches in the carrying case. I would rather have solid accuracy than that eight inches.
