Laylax Nine Ball Aluminum Custom NEO Scope Mount Base for Tokyo Marui Hi-CAPA 5.1 Series GBB Pistols (Color: Heat Gradation)

"This is a sturdy rail. It screws onto your handle and slide release lever. It makes adjusting your hop up a pain but that doesnt happen often so its not a major concern. It's about as good as it gets until you start getting into aftermarket lower recievers with tapped holes. The rail system is very flexible. able to be offset by about 1/4" left or right and you can move the rail forward and backwards about 2". The slide release that is built into this unit functions well. it sometimes will not lock the slide back when out of ammo however. seems to be 50/50.

"Excellent product definitely better than the matrix i got the first time

"It loosens up way to fast, after like 10 shots you can feel the mount wiggle, I would recommend loctite with it. Other then that prob the best mounting system for hi capas without making holes in the lower.

"Install was easy. It would be a good product but somehow the part to place the railing got bent so now it’s crooked. The product is study and I’m pretty sure I didn’t apply too much pressure to bend it
