This is a great rifle by KWA.
This is the first KWA I've owned, and I am impressed.
The rails are pretty cool, unfortunately it's tough to fit both the top and bottom on correctly at the same time, so you'll most likely end up with the bottom on squarely but the top pressing on the delta ring, as there simply is not enough room for them both to fit.
I'm currently running the PEQ box on my right rail, an ECHO1 grenade launcher on my bottom rail, and two CA railguards for the two remaining rails. I replaced the metal carrying handle with some flip-up battle sights.
The only problem I had was that ASGI didn't send me the PEQ box with the gun, which was slightly annoying. It was resolved later, however. I'm glad they included the A1 style foregrips or I wouldn't have been able to play for a while.
I rated a 4 star solely because of the PEQ box issue, the rest of the gun is amazing.
High-quality ABS parts
No wobble on stock or mags
Plastic PEQ box
Rails don't fully fit
