with apprentice type machining on SLR and waiting forever while they refined their design,that magwell looks like it was made by a first year apprentice,that's atrocious machining,ATRS pretty much made Macabee odsolete, BUT,,if they dropped the price to about $600.00.there would be a market for them there,as it stands,who would pay the same amount for a way less quality set,
My stag had issues.... The forward assist wasn't in spec and wouldn't push the bcg forward. Unfortunately the only one available to me was a 139$ titanium variant that I had for another project. I've been waiting for a resolution for 3 months on that now.
I'm very impressed with the modern sporter.
I just received my SLR the other day and have the exact same issue with the gas tube. Sure it’s an easy fix, but how does this make it past QC or is the end user expected to finish machining where they left off?
My serial number is in the #600s, had it pre-ordered from very early on and now I have my doubts and wonder if I should just go with ATRS instead.

The whole idea of having a screw and heli coil as the retainer for the upper is a terrible design.
Prone to stripped heli coil, vibration loosing the screw, etc...
Also the upper can still move forward a small amount due to the size of the hole if it not completely tight or loosens off.
As opposed to the hook and pin on the ATRS which will not allow this to happen.

That was my issue. My screw kept backing itself out and everyone’s answer was “omg just use some loc-tite.” MDI suggested a washer, but wouldn’t supply it, nor tell me where to find one. My problem wasn’t with the helicoil system as I knew that going in. The problem was having to carry a tube of loctite in the pistol grip every time I took the rifle for fear the screw would come loose. I couldn’t trust the rifle and it bothered me which is why I just sold it. I wasn’t even doing very heavy shooting, just casual range blasting and about 70-100 rounds the screw would be about 3 turns loose. Also the small retaining screw that was meant to keep the take down bolt in place did not do its job lol. Lost the take down screw a few times.
Yeah, I’m sure the loc tite would hold the screw in place. But for $1k I shouldn’t have to do that. I also found it pretty off putting at how little MacDef seems to care about the issues people are having. I tried to ask them a few times about the take down bolt and they never replied, or suggested I use thread sealer or find a washer that fit. They just keep pumping out receivers with more and more issues and really don’t seem to care judging by some of the pictures I’ve seen here. My serial number was in the 70’s, and 700 later it still seems that there’s big issues. I’m glad I ordered a MS ( just have to wait until August !).

My MDI set came with several issues, 3 of them I'd be able to fix myself but there are 2 that bother me so I'm sending it back.
1 - barrel won't fit the upper (I just tried freezing the barrel and heating the upper)
2 - BCG feels lose inside the upper, it rattles, I'm not sure how lose it can be without issue, but compared to my AR it is very loose. You can move it sideways with your fingers through the ejection port.
When I first saw the MS I thought of cancelling my MDI pre-order and ordering a MS, but MDI was promised to an earlier date. If I had vaguest idea of the issues and delays I'd have done it.

But then I noticed a couple issues with the machining:

And then there's this ^^^ Not quite sure what happened here
Correct me if I'm wrong, but isn't the smaller screw suppose to retain the larger takedown screw? Doesn't look like there's enough overlap to retain that takedown screw
But that magwell though...

Yes that smaller screw is supposed to do exactly as ypu said.
Quality takes time and was worth the wait....although I was lucky enough to get in on the first production run.
Super happy with the machining, fit and finish. I literally giggled when I first opened the package.
Assembled 2 uppers. One in 224 Valkyrie and another in 223 Wylde.

I often wondered where Stevie Wonder ever got to, now we know. QC manager at a firearms manufacturer.
On a serious note though, that magwell is almost in-explainable. I have no clue how they are doing their magwells, but they should outsource that to a shop with an EDM. There are a few in town.

The problem with machining mag wells either manual or CNC is the corners.
Another Canadian manufacturer would drill the corners, and then mill out the rest. This leaves the metal at the corners very, very thin. In the event of a case failure, pressure can get vented down through the magazine. Very thin metal means the lower receiver will break, not bulge.
Broaching or EDM produce the best results.

Agreed 100% The cost is higher to wire EDM as it is a time consuming process and the consumables are expensive but the end results are far better. A proper broach can cost several thousand dollars to have made and "should" do many many lowers assuming nothing goes wrong.
