I already had a MK18 but decided to go ahead and get another upper for a future build. Like the other reviewer, it originally stated like a 8-10 month backorder but I wasn’t in a rush and figured I had time to cancel my order if I changed my mind. The upper was on sale and on top of that I used a 10% coupon so I just couldn’t pass it up. I’ve ordered a lot from OpticsPlanet (also got a MK12 upper recently that had been on backorder for a while) and they continue to deliver. Love Daniel Defense and love the MK18…also have a DDMV7 and looking forward to a MK12 build in the near future. Phenomenal products. You won’t regret it.

Just wanted to clarify my prior review post – while the backorder indicated 8-10 months (which I was ok with), it ended up being delivered within about a month. As I stated, I’ve been ordering a lot in the last year plus (check my account OpticsPlanet and hook a brother up!) and mostly purchase through OpticsPlanet as they have great prices and timely delivery.

I bought this upper for HRCC. My training and everything so far with this rifle have been flawless. Easy use for entry drills and CQB. Very accurate, even under ridiculously heavy use. Runs great with my Surefire SOCOM RC scilencer on it, spits a little gas at you, but thats normal. Im running a spikes tac T2 buffer on it and that seams to tame down the over gassing DD likes to do on this model. Found a few reviews on people saying that some finnish was chipped on theirs my guess is that they want a "safe queen" and wont run this rifle to its potential anyway. But i deffinetly recamend it.

Received the upper quickly and had a great experience with Optics Planet. Would highly recommend the Daniel Defense MK18 upper and Optics Planet. I assembled the upper onto a Aero precision lower with no problems and everything functioned perfect.

Like anything else needs to be said about DD products. Super light, sub MOA accuracy…but the folks at Optics Planet were great…contacted me about delays due to stock issues and gave me a heads up…but then the next day I got another email and it was on its way!!! Couldn’t have been happier. Shipping took about 6 days.

My favorite upper by far now. Shoots so well. The rail really looks fantastic and you can just feel the quality of Daniel Defense when you take it out of the box. I think buying these uppers is the best way to do a daniel defense rifle, buy the upper, build your lower, and you'll save a ton of money and end up with a fantastic shooter.
