hey guys im looking at buying my first AR in the next few weeks, i have found an armalite and a S&W M&P. i am in the military and until DEC 31st S&W has a 100$ mail in rebate for any new rifle from them for all LE and military personnel so i could get the M&P MOE edition for 870 + FFL thats after the 100 Mail in, or the Armalite Law Enforcement 223 Rem. M4 Carbine/No Carry Handle for 787$ + FFL. does anyone have any experience with these or input please? i have heard they are similar in quality thanks a ton from an AR noobie. also any recommendations of other good manufacturers in the 900$ price range.
