I suggest modifying the lower half of the mag catch so that the mag can go in more smoothly.
I bought this one for my cag mre recce build, the traditional FSB could block sight pictures when using the LPVO at ~1-2x magnification. However, I am not a big fan of the PRI-style folding front sight or m16 low-profile gas block. Therefore, this is the best I can find on the market. It fit all of my barrels and doesn't require an FSB cut on the barrel, and it stays tight on my GHK GBB. I will definitely purchase one more for my mk12mod0 build
I ordered a shotgun shell holder for my Golden Eagle shotgun and was sent the wrong part, received a CYMA shell saddle instead which is a completely different shape with different bolts and after messaging support I got no response whatsoever in over two months, genuinely disappointing
The build is rigid, and the surface treatment is quite nice. I have used it for a month, and no scratch has formed on it. Its surface treatment is a bit thick, causing it to be tight when changing the fire mode. However, It became just right after I used it more times. It comes with three choices of selector lever on the right side, I use the half-cut one, as It is best for me to operate the gun with either side.
Excellent item, just what I needed for a retro look to clip on an Alice harness. I haven't seen these anywhere else. Nice and heavy. Very shiny new, but after a rub with sandpaper it looks great. Will look to buying another with my next order.
