Diablo Mongoose LCD, Crossfire 92/4500, clear Empire Reloader B, Bob Long Torpedo Reg
Any Diablo or Draxxus.
Price, true custom ordering, weight, quality, no bore inserts to get damaged.
Could use a little more porting for quietness, but who cares for air-ball.
All of my friends told me how nice their Empire barrel kits were, but that they found that they really only used the .687 or .689 all of the time. I wanted an inexpensive barrel, because the stock barrel on my Mongoose is way too big bore. I went with a black .689 with Spyder threads for my Mongoose, and chose a 14" black tip because I play air-ball mostly, and am usually a back player.
I actually used to have a 2000 LCD Angel with an 88/4500 Armageddon, and that's where I've used the Dye and the J&J barrels. I had to sell everything though because I needed money.
My Mongoose shoots just as fast and accurate now with my .689 Empire 2-piece as my Angel ever did. I can shoot ropes with it now, even walking the trigger to 15 bps, as I shoot semi-auto only for air-ball. The accuracy is amazing.
Anyone who wants one upgrade barrel, and wants it in an exact size/length/color, should absolutely buy an Empire 2-piece. This barrel is as good as anything on the market today. Like I said, I used to have an Angel LCD with Dye and J&J barrels, and my gun is just as good as an Angel now that I got my Empire 2-piece barrel. And you can order both pieces for about $55-60 from most websites, which is a lot cheaper than a Boomstick or Freak Jr.
