Taken it out to the range a few times, I was nervous since I am new to AR's and had to replace the gas block. Was worried I didn't get it on straight or something. But it ran like a champ other than one time a LAR mag held the bolt open as if it was empty, still had 7 ish rounds in it. I love the handguard, it is very comfortable and ergonomic, and I don't have to grab rail. Very happy with that purchase. The Mini comp from Rainier is bloody loud and sends out fireballs each way, and does a very good job of keeping the gun on target. No problem rapid firing steel at a little over 200 yards.
