	How can i find out if my bushmaster lower is pre ban or post ban? And does the preban or postban even matter anymore since the ban went away?
	Sir.Ma'am, My weapon is marked 223/5.56. I read that you can can safely chamber the 5.56 but not to shoot it because of the pressure differance. I have federal ammo in 5.56 which I guess i can't shoot as is. Is it the powder or the "extra throat" that makes the pressure a problem. They probably will not take the ammo back. If it is just a throat problem can i seat the bullets a little deeper? Thank you.
	I recently purchased a Varminter based on internet reviews which I really like so I ordered a 16"Carbine M4 Complete Upper, A3 Version and now my buddies are telling me what a mistake I made. They claim that the barrels are inferior grade 4150 steel, that the front sight is not a F type and will be to short to use with my detachable handle and that my castle nut and gas key want be properly staked. I don't even no what theys are but now I'm concerned, is this true and do I need to be worried?
	I recently purchased a Bushmaster AR15 O.C.R my question is which is the proper ammunition for this weapon? The lower receiver is stamped as follows..CAL 223-5.56 MOD XM15 - E2S. I have Remington UMC 223 rounds I was wondering if I can fire 5.56 rounds in this rifle safely (I have read it can be dangerous if fired in a short leade ) also if 5.56 rounds can be safely chambered and fired what is the distinct difference between both calibers.. any information you can provide would be greatly appreciated as I would prefer an answer from the manufacturer then from an online forum.

	Does the Bushmaster O.R.C. rifle have a threaded A2 flash suppressor?

I have seen some online dealers listing the rifle as having the flash suppressor permanently attached but I can find no hard data to confirm or deny it. Thank You.
