I have about 4K though mine now and it has been great. My only real complaint is the height of the iron sights. IMO, they would be perfect at 1/4 inch higher, but up to 1/2 inch would be okay too. As is, they can't be properly viewed though any RDS I have tried. The TRS25 is very close, but not quite there. I can cheat and still hit 12 inch plates at 100y, but can't truly see the sights when on target. The additional height would allow dozens of micro optics to be lower co-witnessed. An easy answer is a QR RDS, but it doesn't take much additional mounting height before I want a cheek riser too, at which point the irons become difficult to use if required. This really is a minor issue, my work around is that I carry an allen key in the stock pouch and can pop the TRS25 off if it fails.
I like the almost traditional rifle look it has, and am leaving it with factory furniture. I have a cheap stock pouch on mine, which holds 3 Glock 26 mags. I made a small opening on top stitching of the velcro inside the zippered pouch, and carry extra 2025, and the RDS allen key behind the velcro. Extra CR2 batteries are in a small sleeve sewn into the corner of the main pouch.
The stock pouch was under $14 on Amazon.ca search for Buttstock-Shells-Holder-Hunting-Shooting
I don't mind that the rail is small, and you can't use big lights and a sling at the same time. The rail is perfect for sling with a pistol tac-light, which I have a many. I use a Streamlight TLR4 on this gun, because very small/lightweight, it only uses one battery (CR2 even smaller than CR123) and you can lock it off with a 1/4 turn of the head unit, so no accidental use when in pack. Another nice thing about pistol tac-lights is QR with tool-less tightening.
Glock 26 mags are perfect for non-competition use of this gun. Enough exposure to grab if needed to pull them out of the magwell, lots of spring pressure for feeding and bolt hold open, compact enough that you can carry many extras, and can carry a mag in a bladetech pouch/teklok on my belt all day without it ever driving into my hip, no matter how far I lean. I shaved the pouch a little to get a little more real estate when drawing the mag.
Overall this gun is a great fit for my needs, and I am very happy with it. Sight height being the only thing I would really change (and 10mm!).
