A-5 with proteam sniper stock, 10"barrel with shroud, reactive trigger, and intruder expansion chamber.
sturdy, comfortable, looks cool, helps aiming (depending on your style).
slight difficulty sighting due to mask interference, but a sight rail will fix that.
I went on proteam's website, and ordered the kit from their. It came assembled,so I have no idea how easy or difficult it is to install the stock. I'll find out next time I take my marker apart I guess. It's a little bit pricey, but I got my tax returns in and figured what the heck. I was a little worried before I ordered it that it might be kinda flimsey, but it was actually very sturdy. Depending on your mask, you might have trouble sighting down the barrel, but a sight rail will fix it. My friends can't get over how cool the marker looks. Also, I'm pretty sure you have to use a remote or the intruder expansion chamber , drop forward, or attach your tank vertically because the stock interferes with the conventional attachment point. I bet this will be helpful to flatline users who need to keep their markers perpendicular to the ground in order for the backspin to function properly.
If I was going to upgrade a marker in increments, a stock would definately be lower on my list than say, a new barrel. But if you have the loot and like the look, its definately a worthwhile product to buy. I give it a 9 instead of a 10 because of the slight sighting issue, but besides that, its great.
