JW, you didn't confuse me, or, anyone else that I am aware of. I'm sure you might have helped someone out there in the AR world.I apologize for the confusion. I am new to the forum and got excited when I saw that I could try and help someone. As I found out when doing my handguard on my AR556 any handguard will fit you may just have to put a mil-spec barrel nut on or the proprietary one for that brand. As far as the original barrel nut and fit of handguards I'm not completely sure. Again, I apologize for any confusion.
JW, that's the cats a**! I LIKE IT! But, you NEED a MAGPUL stock. Let me help you spend your money;
