I own one but don't have the burst installed.
Seems pretty reliable to me but I've shot less than 1000 rds through it.
It's fairly heavy for its size (more than an AR) and there aren't as many parts and accessories like there are for AR's.
It's a nicely made weapon but the trigger just plain sucks on it, plus no bolt hold-open on the last shot.
Not as magazine sensitive as an AR but really crap mags will still occasionally cause feed problems (double feeds).
Longterm parts availability is my biggest concern but there is some hope on the horizon.
It's a cool rifle, you'll have fun with it.
