i love both of them! the 98 custom is nice because there easy to break down and so many attatchments and i own the bt16 tatical with the push pin system wichis even easyer to break down. and the thing that i dont like about the bts are that there are no sites because the feed neck is in the way. but you can buy stuff to move it around or put rails on the sides for night vision scopes ect... i enjoyed the bt for when i played senario and everything that fits on a 98 custom fits on the bts same threads. if i were you id go bt cause it comes with stock,m16 barrel or ar15 barral. a fore grip. and a handel on the top. and if you get bt there on the heavy side with the tank on it but if you get the right pod belt you can buy a remote line and have the gun halh weight and you can do all the same stuff and i might be able to sell you a bt16 tatical pod belt hopper remote line and a 20oz tank for like 300 cause i spent 400 on the bt tatical and its in perfect condition and it has a scratch on the end of the barrel and a dye sticky grip
