hey guys, I just purchased a beauty of a rifle, my question is for anyone who actually owns a gen 2 B&T APC 223, I only have about 100 rounds through it, while I stripped it today for cleaning, I noticed that the barrel /piston housing does move a tiny bit from side to side in the upper hand guard. I can move it about a 1/8th of an inch play, im wondering if this is normal? if anyone has any feedback I would greatly appreciate it. I love the rifle though, what a slick unit. I bought it brand new so its not been abused (yet lol).
