Simple but effective design - FAB Defense Handguard Accessory Rail System For Mossberg 500/590

I wanted to mount my Streamlight TLR-2 red laser/light combo on my shotgun, and needed an economical way to do it. This fore end (FAB Defense Handguard Accessory Rail System For Mossberg 500/590 PRMO Code: 1S0-T8-PRMO)
looked like the way to go, as it had integral Picatinny rails on all three sides. It turns out there is another important reason to mount the light on the fore end slide: your supporting hand moves with the slide, so your thumb is always in position to work the light control switch.

This item was well designed and constructed, and went firmly on the Mossberg 500 slide without a hitch - like it was custom fitted. I ordered it to go with the Magpul Industries SGA Shotgun Stock for Mossberg 500/590 (Code: 55-SK-DSKI-MPIMAG490BLK), which I'm reviewing separately, and which was an excellent match (looked like they were made as a set). I wound up mounting the laser/light on the left-side rail for ready access to the switch, which means I had to choose the range at which I wanted the shot pattern to "zero"; not a big deal with a defensive shotgun.

Both items arrived in the same box in record time, and since I was over the free shipping threshold, I effectively got one at a "discount", by ordering them together.
