"great little Hop-up unit, bought it to replace my factory plastic one.

I was however a little bummed to find out no other pieces where included other than the hop up arm pin. i had to use the old adjustment wheel and arm.

it is an excellent built up grade part, finish is excellent. after putting it together and installing it i notice a slight bump in efficiency and FPS, along with my promy 6.03 barrel, lonex 70d it shoots lasers.

I only wish it included the black hardware.

over all i suggest getting it.
