Matrix Graphite Upper Rail Mount for Hi-CAPA Series Airsoft GBB Pistol - Silver

"Lines up perfectly with my TM Hi-Capa 5.1, extremely sturdy well manufactured.

The only negative is that the included grip screw was too long, had to grind it down or it would scratch up my mag.

"Mounted easily. No tolerance issues, rail sits perfectly parallel with the slide.

However, the two provided grip screw replacements are too long, and hit the mag upon insertion. So plan on a trip to the hardware store.

"This mount is amazing, I don’t have to worry about drilling holes in my hi-Capa I can just screw it in to the grip and use it instead of a slide lock. Which wouldn’t really matter since I short stroked it. The mount is very stable and I would recommend it 10 out of 10.

Pros
Don’t have to drill holes
Stable
Easy to install
Really low to the gun
Doesn’t sit really high
Can adjust how far you want the rail forwards or backwards

Cons
None at the moment but if theirs any I will get backed

"The best fit and low sitting rail, just clear the stock rear sights. However, as most reviews said, I scratched a mag upon insertion due to the shortest screw that came in the package was still too long... Stick an O-ring on the screw or get a small washer to space it out a bit...

"I'm sure it fits on the tm hi capa better... Have a we tech allosaurus, it doesn't mount in line with the slide... It is on there.. however the rear is slightly lower than the front of the rail, making the red dot tilt upwards ever so slightly.. i feel like you could make it sit right with some shimming
