- Awesome pistol, easy to manage and shootAwesome pistol, easy to manage and shoot. First pistol in 300 BO. I have 2000 rounds out of it so far. It's not light but the weight offsets some of the recoil. I put a Silencer Co Chimera suppressor. It's quiet, stays on target, little blowback. I'm a regular shooter and have good grouping's out of this one. I keep this guy by the bed for home defense.

- Quickly became my favorite DDThis is only my second rifle, I also own a DD M4A1 14.5", and within a few rounds it quickly became my absolute favorite gun I own. I paired it with the DD SoundGuard 30-Ti, Eotech Red Dot and Cloud Defensive REIN Micro light. The ATF was quick to turn around both form 4's for the can and SBR. It's an absolute dream to shoot and when I let any friend fire it, they instantly know that they need a DD 300 BLK in their life. If you are thinking of getting this rifle, don't hesitate, you won't regret it.

- DDM4 PDW SBRI went ahead and purchased as an SBR and suffered through the wait. Compact, light, portable and enough thump to stop anything that might want to cause you trouble. Just like a credit card, I never leave the home without it.

- Impressively AccurateFinally got one from local dealer(the only one they received). As I was going to wait for my EOtech 300 blk sight to arrive before i tested our new range out..I couldn't wait. Even without a scope or HWS..at 50 yards..first shot dead center of bullseye target..amazing. Picked up my EOtech today so tomorrow will be sighting in. Recoil?..what recoil. Love this pdw. DD did it perfect..with exception of trigger which I installed a flat faced 2.5lb rise armament. It will be complete as soon as I install my Olight baldr mini.

- The wait, the possibilities, the defense.Yes, I purchased one a few weeks ago along with the Wave Suppressor. And no, I don't have it in my possession yet. I have, hopefully, 10 months or less to go to have both in my vault (Form 4). I had the opportunity to test out a friends (non-SBR w/ no suppressor) and I am highly content and more than happy with the results. My PDW SBR will be my travel rifle (in vehicle) and go to home protection if not my BUL UL. Rather than get into all the technicalities I will say that my groups were decent; like any other gun/rifle it's a matter of consistency and practice/training. This is my second DD product and if all goes well in the foreseeable future I may purchase the M4-V7 LW.
