- Fantastic System, but Disappointing TriggerEverything in the design and function of the PDW is excellent--except for the very disappointing gritty 9-10 lb trigger. It will be replaced to make this the perfect truck/home defense weapon system. It would be a simple matter for DD to include a quality trigger to make this a true top tier firearm.

- First SBR, bar has been setLove this weapon! It shoots as promised-it’s compact, maneuverable, and accurate at a variety of distances. I’m running with a Holosun 510-C Green dot and an omega 300 can shooting subs and all you can hear is the action cycling and the projectile hitting the plate. I will add that I decided to upgrade the trigger to a Geissele SD-E 2 stage 3.5 lb, and man did it make a world of difference, literally the only thing I would change on it. Absolutely worth every penny!

- Awesome PDW out the caseI’ve put about 1000 rounds through it and like my other DD has proven reliable and super compact. It’s quickly becoming my favorite CQB platform. Don’t build just but this and you won’t be disappointed!!

- Solid Personal Defense WeaponSeveral thousand rounds and no issues whatsoever. Most of those suppressed with Dead Air Sandman S. I use this as my home defense and truck gun. I have 3 Daniel Defense rifles and have never had an issue with any of them.

- Outstanding Weapon SystemI’m very happy with this weapon. I did add the Holosun HS510C, it’s a great addition.
Accurate, versatile, perfect size and weight, and fun to shoot.Posted on
- 1st 300BLKMy 1st 300BLK and absolutely love it. Waiting on the DD Wave now. Cant wait for the MK18riii release. Daniel Defense makes the best rifles imo.

- It’s goodNot a fan of the trigger, safety selector, or pistol grip. A Geissele SDC, ambi Radian Talons, and Reptilia CQB pistol grip later and it’s the perfect home defense/backpack gun ever.

- On a scale of 1 through 10 I rate this a 12!This little girl is crazy accurate with any ammo I've fed her! Sig, Federal, Striker and Gorilla all make one hole groups at 25 yards with a non magnified Green Dot and my 68 year old eyes. And she's dead sexy just to look at. I would highly recommend this to anyone thinking about an AR pistol over any other brand out there, period!
