I can answer that. I accidentally bought one... Very, very pleased with function. Brand new, with a cleaning and lube beforehand, it ran flawlessly through 6 mags. I paid $1,132, another $14 for insurance, and $20 for transfer (although I felt bad about having it shipped to Quentin Defense; I did apologize to them but they're too nice to be offended).
With the sling, loaded 20 round mag, 1-6 illuminated scope (I assume the electronics add some weight?) and Burris PEPR QD mount, the rifle weighs 12.2 pounds, so a full 4.4 pounds of extras on there. But still not too bad.
The pic below is a target at 50yd during sight-in, using factory Prvi 147 ball. I did not play around with the gas port adjusting because I have to find a load it really likes, then once I've developed that, I can fiddle around and adjust the gas.
Recoil was gentle, but the brake won't make you any friends (in this case, both my son and my son-in-law were not real happy with me!). I know it sounds petty but it made such a nice little pile of brass that it made me happy at the end of the trip.
I hated the trigger that came with it, so I replaced it with a Geissle SSA-E which I put on every AR.
I'm happy enough with the accuracy but I couldn't get out any further to see what the real MOA is. When I do I would be happy to update this, but for now, at 50 with the cheapest factory ball I could find, I'm pleased enough with accuracy. Those are 5 shot groups.
Let me know if there's anything else, but in general, this is an excellent rifle, and definitely a keeper. VERY pleased; just not done testing limits!
Also, if we know each other (or share a referral in common), I would be more than happy to loan it to anyone to take out and test before you buy.
Also, dang... I forgot to weigh it with a 25 round PMAG, sorry. Just the 20's. One last thing: I took a video of my son shooting it to show the nearly non-existent muzzle rise, but I have no flippin idea how to post it. If you PM me your number (I'm speaking in general, to anyone) I can text it to you, or someone can post or PM me how to do a video that's on my phone. But be explicit!
