"This is a great rail system. In my case I had a very minor issue that was easily solved. I have a KM4-A1 and this rail system didn't line up perfectly with my stock rail. This was easily solved by sanding down my stock rail a little. I was not bothered having to sand because I have no intention of taking it off.

"Great product, and excellent quality. An exact replica for any airsoft clone build!

"Fits right onto a standard m4, with a slot for the front sight and hugs the delta ring, this rail is plug-and-play and takes less than 5 minutes to install properly. Attaching directly to the upper rail offers stability, with little to no movement after mounted, and the rails are long enough to offer enough space for any attachment you're looking to add.

The metal is a 4/5, not the best, but doesn't feel cheap, and I'm not worried about chipping or scratching it. The lower guard attaches with a pair of pinch tabs near the front, and swings down, offering space for a front wired battery. Plenty of space for a battery, more than the standard handguard, so if your gun was front wired, this rail will still work for you. That said, installing the battery is a bit awkward due to the way the rails fit together, which I fixed by adding velcro straps to the rails and my battery, so they don't move around while I'm sliding the lower rail back into place.
