I had mine out today for 150 rounds in -18. I took it out of the box, slapped on an optic and flash hider, no lube, pre-disassembly, or anything. All 55-grain Western Metal factory reloads.
Functioned flawlessly with MDT 10 Rounders, PMAGs, and C-Products pistol mags. The Cross Mags I had did have one malfunction, possibly a short stroke, it just didn't pick up the round and the mag was seated correctly. They worked fine the rest of the day though and all magazines dropped free.
Didn't get too much accuracy testing because it was cold, but it consistently hit a 6-inch plate at 50 just shooting while standing.
Pros: The finish is very nice, and the thin diameter rail and weight just feel right. I do not find the rifle front heavy at all, the action is smooth and the Zhukov stock is nice and solid. The height of the stock to rail is similar to my x95, so a little taller optics mount is nice. Nothing was loose when I went over it after the initial firing, time will tell if everything stays tight.
Cons: The charging handle is a POS. If BCL sees this, PLEASE make a large folding charging handle, even if it is aftermarket. any optics mounts that stick out at all will wreck your knuckles and overall it is just too small. The trigger and safety are crap, but so were the factory ones on my Sterling r18, Kodiak Wk180 Gen2, and any basic factory AR15 I have purchased n the past. They are easy to be replaced and will be, for now, they function just fine and are what I expect.
Overall, I will keep this over my Kodiak which EVERYTHING came loose- the gas block to the point of malfunctioning during a range session! I also prefer it over the Sterling R18, Mainly because of its weight. I found the Sterling to be a 308 gas gun in size and weight and would make a better "bench" or DMR-style gun if that is how you shoot.
I plan to just keep running it to see what problems occur, with no cleaning or tightening until I have to. I will update you if anything arises
