Thanks for being the beta-tester chiefmichael!
The magazine angle is surprising, I was expecting it to be vertical and the bottom angle was just how they shaped the mag-well. With drop-free mags and assuming it is reliable, it has to potential to be made into a killer suppressed SBR.

Ok, just got mine today...threw a bunch of spare stuff I had on it and headed to the range. Ill do a full review later but this is what my experience consisted of:
Packaged was the rifle, one mag and a mag sys manual meant for a normal ar15. Some other buyers have mentioned no manual and no mag.
-The rifle seems to be of decent build quality, however there was some play between the upper and lower. I have a RRA Ar15 which is absolutely tight / no play, so this is not something I really am ok with even though I know some AR's are like this.
-The factory mag and glock mags were hard as heck to put in until it loosened up some. With time I see this will improve.
-I was UNABLE to install my PA optic on the rail because it simply was too narrow by ~ <1mm. The UTG riser would clamp on, then easily slide forward and aft once tightened down. Unacceptable. The upper's rail also did not match the UTG pro forward grip rail. The optic had to be installed forward of the upper's rail on the UTG pro handguard where it fit/held fine. Now we'll see if it holds zero there.
-The trigger is decent and seems to be a normal AR-style that you can upgrade if you wish.
At the range I proceeded to first sight in my Magpul backup irons, then my Primary Arms reflex sight. I sighted for a 25 yard zero, which will work well out to 100 yards. (+1.2 @ 50, +0.9 @ 75, -1.1 @ 100). It did prove to be fairly accurate.
The first 200 rounds were done using Anguila 9mm 115gr FMJ and only the supplied factory (Korean) "glock" mag.
-No failures of any sort.
-Accurate.
-The gun is overall very light and a pleasure to shoot.
-------------------
Then I switched over to Glock mags preloaded with Fiocchi 9mm 158gr Subsonic FMJ and Precision One 147gr Subsonic.
From here.....things kind of went downhill. I got to a point of having several FTF's every 10 rounds. All the previously experienced reliability was gone. Pictures of the FTF bullets are below. It did this with the suppressor and without.
Range Day #2:
FTF Culprit: GLOCK FACTORY MAGS
100 Rounds of Winchester White box 115gr, 50 rounds of Anguila 115gr and ~30 rounds of 158gr subsonics....all with NO ISSUE what so ever using the Korean KCI included magazine.
Switching over to a Glock 33rd mag and Glock 15rd mag...and it would fail to feed 33% or more of the time all with the same ammo that was previously fine.
Looking at the two mags they are fairly identical except for the angle of the bullet. In this picture you can see that the KCI magazine has a higher "departure angle" than the glock mag, which is where I believe the difference lies.
-------------------
So there you have it....an AR15 that accepts, but will not function with glock mags. You are essentially limited to the Korean included mag or test other mags to see if they work. Id be curious to see how the new magpul 9mm mags will do. In the meantime I ordered two Korean / KCI 33rd mags from Centerfire Systems to see if they will work. I also sent an email to Mag Tactical Systems regarding the issue.
15 rounds @ 25 yards w/ Red dot

Many of the Korean Glock mags need a few touches of a belt sander to drop free. The newest ones I got from CDNN for $10 "on sale" have been much better.
Your "jam" photo looks like a classic "bolt over base" failure where the mag fails to get the base of the cartridge into position in time and it catches the extraction groove instead. I'd try some 147 gr ammo, I've never seen 158 gr 9mm and would be very leery of it! Doesn't take too much extra OAL or loss of case taper to cause the 9mm rounds to bind in the magazine.
Never heard of "Precision One" ammo but Glock mags made me adjust my 147gr reloads that were fine in a 9mm 1911, EAA Witness, and S&W M&P.

Hmmmm, looks like a sweet rifle! A couple of problems but for the price doesn't seem to be a show stopper. I love my Beretta storm, but I could have seen me buying this instead.
Keep us updated!

Hey, I'm the guy that started the thread you linked.
I got an email back this morning from them telling me to pull the buffer to see if it has mushroomed. I won't be home from work for another 8 hours, so I figure if you get the chance before me it might be worth looking into.

I want one also, but they have to sort out the bullet feeding problem.
Wally, have you come up with a bullet OAL that seems to work best? I reload and could
make anything that works.

I use Berry's or Xtreme 147 gr plated with OAL of 1.150"
I had to reduce the OAL from my initial 1.180 to fit my Glock mags, but now this works in all my 9mm guns.

Thanks Wally. I'm running about that OAL now with 115's so maybe they'd be OK. Sure hope they get whatever causes the hangup sorted out. Really would like to have one.
Update:
I have been in contact with Dave at Clearview Investments, who seems to be the point of contact for these rifles. He has provided me with quick responses and excellent customer support so far. He assures me they will get the rifle sorted.
Issue has been narrowed down to vertical magazine play in magwell, affecting the bullet height in relation to the chamber.
Apply pressure to bottom of mag, no issues. Otherwise magazine lowers and bullet does not make it into chamber.
There is some play in the mag release and someone on another forum suggested a simple washer in between to take up the slack.
I added a small washer which would fit around the pin but be as small in diameter as possible. So far I simply ran the bolt with my hand on a Glock mag with 115gr and 158gr and had NO FTF's whatsoever, where as it definitely would before. I am looking forward to shooting it again and seeing if this could really be that simple and inexpensive of a fix.

I received my Nano last night, and hand-cycled several mags of Wolf mmo through it with zero FTFs. I then added a temporary shim and cycled a few more mags, with zero FTFs. However, just to be safe, I'm going to permanently shim it anyway. I don't have any washers that are thin enough, so I ordered some tiny delrin washers from McMaster Carr.
FYI, the gap on mine is 0.024".

I got the gap shimmed, and found that the magazine takes just a bit more effort than I like to seat properly. I never had any issues stripping rounds without the shim, so I may remove it.

Any update from owners?

I'll go out on a limb and suggest that no news is good news. People are quick to complain about problems, not so good at following up about solutions.

Unless there is something about the shelf or the shim that would prevent it from rotating you'd risk it preventing magazine insertion should it rotate and protrude into the mag well.

What's it weigh? Looks nice but hefty
