I saw this thing at D-Day 08 at their tiny little booth, and was hooked on the spot. Since then I saved my nickels to get it. I ended up getting an A-5 that never been cleaned ever and the paint had been worn through but for eighty dollars and fifty cents I wasn't complaining much. I finally got the kit and immediately set upon getting it set up. A little tip: when you install it get a fresh 9v I took mine apart 6 times thinking the sear and solenoid weren't lined up right.
best thing about it is that it cuts the size by 3/4. My B-5 with my 16" Bangstikxx is shorter than my BT-4 with the 8.5"Sharktooth. Big advantage when your playing tight (especially in hyperball) The full-auto is nice but the reactive mode on the gun is quickly becoming my favorite. The length is also a bit of a weakness, It puts the cyclone feed right next to your face and you can't look straight down the marker. Get the X7 loader or the richochet to fix this.
Weaknesses are numerous but can be overcome easily. To start you art stuck with the A-5 and that gas hog they call the cyclone feed, which I'm not a big fan of. But thats my own opinion. 2nd its the back plate needs to be adjustably by like 3 in. Its fine for a guy that is 5'8" but its a little too short for me being 6'3" and finally you have to play remote with this. Now I like playing remote but remotes are finicky and have let me down. The only other weakness is the Price. $599 fully assembled, $325 A-5 not included and $175 A-5 and Electronics not included. If they'd lower the price on the full one by $200 they'd sell a billion of em.
