I have one. i have since removed the front built in bi-pod and replaced with the compact fore-end. I have also put on the AR style pistol grip stock. With that stock it still does fold but it not very much. I use LAR15 mags as well as PMAGS and both work fine. the mags that come from the factory with it in my experience were junk. Over all i love mine. Currently i have it out at DLASK gettin the barrel threaded and a compensator installed. My red-dot just got here in the mail today for it as well. I will post pictures of it once i get it back and all together.
To those that would tell you to save up for a different rifle that you dont need to upgrade... that is an option but for people like myself who have a hard time saving up enough for A tavor or XCR, It has allowed me to get a rifle that i find to be fun, and functional. piece by piece. At the end of the day, Haters gonna Hate. everyone has their opinion. Its too bad you arent in the lower mainland or you could come and try mine out before investing the money.
