--LIGHT; Self-explanatory. Lightest mainbody I have ever held, makes a HUGE improvement from the standard P/F Body.
--Autococker Barrel Threads; Having barrel threads of one of the most popular markers, the Autococker, makes buying and selling convenient and easy.
--Angel Detent/Feedneck Threads; Using the same detents from one of the most popular Fully Automatic Electronic Markers is saying something there. Same with the Feedneck.
--Expensive; 140 new is pricey, but worth it.
--Can be easily damaged; The Aluminum is very thin and not the strongest material. It can be run over by a car and take minimal to no damage but up against pointed object (IE: Rocks) it loses the fight. The anodize on it out of the box is very weak too, I recommend getting an second ano on it at some point.
A must have on any of your AGD Markers (Except the X-Mag...). It will significantly reduce weight and improve overall looks. With the Autococker Barrel Threads it will be a lot easier on you when buying used barrels.
