I just bought one (elsewhere) and spent the last couple days with it at the range. It’s working flawlessly for me so far and I love the fact that it’s compatible with many AR parts... allowing you to upgrade or change many aspects of it.
I’ve put 6 boxes of various ammo through it and it ate it all from steel to brass, 55, 62, 72, and .223 or 5.56. It’s not fussy. It works great with my LAR mags.
The fact is, there’s not a lot of choice. If you want a tactical sporting rifle, this and the similar (but harder to find) WS-MCR are really your only choice. So while I’d much rather have a quality AR-15, this will do nicely. It’s better than nothing.
