5KU Aluminum Fixed Outer Barrel for Tokyo Marui 5.1 Hi-Capa Airsoft Pistols (Color: Gold)

"Fairly nice barrel could have used with a little longer time in design however I found how to keep it in place. This barrel relies on 2 set screws vs the clip in and over way with the stock. I set the screws in as hard as I dared it is aluminum after all. After the fourth time of taking it a part to tighten the set screws I matched a drill bit to the size of the super small Allen set screws and I drilled into the HopUp slash bucking housing 1/16 of a inch or so problem solved. Good barrel now

"Amazing for the price and ultra light weight. Only problem is that its actually an APS outer barrel according to the packaging. No big deal though since its an incredibly well built outer.

"Anyone know where to get replacement screws for this? i was foolish enough to lose one.
