2) Next, you pull open the cam lock lever located at the lower right side of the fore-end just forward of the receiver and then pull out the captured rail-retaining pin that was concealed by the cam lock lever. Also, if it has been fired recently, make sure the barrel is cool enough to touch. To take down the CDR-15, you must first begin by 1) engaging the safety, clearing the firearm and locking open the action. The actual process of disassembling and reassembling the carbine is a model of simplicity.
Of note is the fact that the upper receiver assembly of the CDR-15 can fit on any standard AR lower, and the takedown barrel system simplifies switching between calibers. The result is the ability to transport a fully functional AR-pattern carbine easily, yet have it accessible very quickly. With the throw of a lever and then some twisting and pulling, the user can break the CDR-15 down into three primary components (receiver/buttstock assembly, fore-end and barrel) that can be fit into an included 20”x16”x9” Plano hard case with custom-cut foam inserts. However normal of an AR the CDR-15 may appear to be, looks can be deceiving.
The carbine features a Magpul MOE six-position collapsible stock, an ERGO rubberized pistol grip, a flattop upper receiver with Picatinny rail, a free-floated fore-end rail system with a top strip of Picatinny rail and the capability of accepting Magpul L4 rail panels, and a muzzle topped off with an A2-style muzzle device. From its forward assist to its shell deflector to its top-mounted charging handle to its traditional controls, the CDR-15 should be very familiar to anyone who has used an AR before. In its assembled form, at first glance the direct-gas-impingement CDR-15 appears to be a reasonably straightforward AR carbine with 7075-T6511 billet aluminum machined upper and lower receivers. One of these is the 5.56mm CDR-15 (also offered in 300 BLK).
#DRD TACTICAL APTUS REVIEW SERIES#
Patel and DRD have developed a series of semi-automatic rifles that feature a quick takedown mechanism that allows you to fit these capable firearms into deceptively small cases and assemble them in seconds rather than minutes (or hours). Company owner Skip Patel is something of an ingenious mad scientist when it comes to radical gun design, and the company has always struck me as being the Skunk Works of the firearms industry. So, is there another way to take down the size of the AR, one that requires some “outside of the box” thinking? Well, you need look no further than DRD Tactical.
#DRD TACTICAL APTUS REVIEW FULL#
Carbine variants of the design (culminating in the M4 Carbine of today) attempted to bring down the size of the firearm by employing shortened gas systems and barrels as well as collapsible stock systems, but the receiver extension/buffer tube assembly design of the AR prevented the design from being shortened further (apart from some more esoteric solutions such as full folding stock systems that either move the recoil spring assembly above the barrel or fold the actual buffer system and render the AR as a single-shot until unfolded). In its original military-configuration form as the 5.56x45mm M16, the rifle featured a 20" barrel and a fixed stock. The AR-pattern rifle has many positive characteristics, but extreme compactness is not one of them.
