They're easy to flip for a profit

Tried mine out yesterday as well. Ran like a sewing machine
I got a Maple Ridge 18.6"barrel with a mid-length gas system and I'm planning to shoot heavier bullets from my build, and I saw a lot of people complaining about it saying that it should be rifle-length, too much gas...yadda yadda...
Should I use an adjustable gas block? Or never mind, move on and install a regular gas block on it?
Well, got mine, and there are several issues.
1; steel mags don't work. The milling in the upper reciever is more rounded and doesn't allow the "square" leading edge of the mag to sit high enough to become seated. Pmags seem to work. Doesn't help much since this was a Grendel build.
2: safety is ridiculously tight almost immovable. Though I'd sand down my selector switch, no luck. It appears that the holes drilled for the selector switch in the reciever and the trigger block sleeve don't line up perfectly. Stupid, annoying, I could fix that but that's definately another manufacturing defect.
3: most importantly, like other have experienced, very tight tolerances with regards to pins. I decided to sand down my roll pin for the bolt catch. It was working until the last 1/4 going in, I hear a crack, and there it is, a nice crack going lengthwise in one of the bolt catch "ears". It didn't crack where they attach to the side of the reciever, the roll pin itself split the aluminum.
Don't say I was being too tough with it, not my first ar(ish) rifle I've built. I sanded that pin down a LOT. There's no way that hole would be of any acceptable specification.
Only plus side is that the rifle looks ###y as hell, and macdef actually asked me to send the reciever back to them. Lets see what comes of this.
Last update in July had me at 108. Where you at TNA? Any changes to allow for some of the noted issues? Have parts for a Grendel build. Really suck if my mag don't fit.
I have a grendel build, and use Alexander Arms metal mags. They didn’t fit, without a fix. Not sure if they have corrected the upper receiver to fix the problem, but if not, you can fix it yourself or send it back to MDI to fix for you. Maybe TNA can confirm specs on yours before anodizing knowing that you will be using metal mags.
How did you fix it?
Do you have any pics of the spot you had to file?
When i see those 1k receiver needing filing to make em work... makes me glad i cancelled my pre order.

Wow... Is MDI taking these back for 'fixing', or is it a DIY solution-only??
