Bought this a few years back. It's a DDM4V7 Pro model. 18" barrel factory Geissele 3-gun trigger. Comes with factory DD hard case and Factory Unopened DD magazine. I've shot it maybe 3/4 mags total through it.  I'm more into other guns than this so I'm going to move it. I installed a Vortex Viper PST Gen 2 1-6x24 MRAD optic with a one piece scope mount. I still have never sighted the gun in since I installed the scope a few years back. There is also a Vortex quick throw lever and Vortex Defender Scope Caps installed. There's a Mlok pic rail for a bipod on the front and a Magpul Advanced Forward Grip.
Scope -$500-$600 online

Mount-$90?

Quick throw-$50

Scope caps-$50

pic rail and grip-$50

Best price I can find on the gun new is around $2200 on gunbroker. You still have tax, cc fees, and transfer fees.

call for questions I would sell the gun separately if you didn't want the optics, but if your in the market for something like this, it's set up!  785-4three4-six58six
