I myself like the 16" bbl I would'nt get a brake of any kind, they are really loud, and with such little recoil, I don't see a real need for it, Removable carry handle? I don't know, will make it much easier to mount scope if you want, Fluting looks cool, not sure if it really works like they say....AWB sunset? Don't know....If it does, I'm sure you could get a F.S. installed, Cost, prices seem to have rose(in my area,anyway) after 9/11, (I bought my 16" bushy in 8/01, and it was on sale for $699.00 same place now has them for $829.00, figure at least $800.00, shop around, there are some deals to be had if one takes the time to look around... load up on mags, get good USGI mags, or Thermold 30rnd mags Don't waste your money on USA brand or Western brand aftermarket mags, they are unreliable junk, you'll have few, if any problems with USGI or thermold, and USGI mags are easily rebuilt, bushmaster sells rebuild kits for 20&30 rnd mags.Check Troy's articles on mags somewhere on this board, he's right on the money, I took his advice and haven't had a problem with mags....Have Fun!! you'll love your AR!!
