This fits the AER-02 perfectly and sits nice and flush on an M-lok rail. No complaints at all.

This mount is a must have extremely pleased with quality and ease of mounting. No one makes a mount as good as this

Use Fenix lights as my personal flashlights, lanterns and work lights, so when looking for a light I knew would be rugged, reliable and would let me light my target, I knew Fenix was the way. The mount is solid and was easy to get on. No problems in over 2000 rounds

This works great for it's intended purpose, and I love that it's very low profile. The switch is held securely, but a couple of small tabs to lock into the zip tie notches on the small end of the switch would be great because the switch isn't hard to push out.

The main problem I've had is the included screws. The c-clip to keep the screw from backing out is gimmicky, and I had to remove the c-clips to be able to mount this to a Magpul polymer handguard. When I moved it to a Midwest Industries aluminum handguard with a Colt M4 heavy barrel, the screws were too long and hit the barrel. I cut the screws shorter, so they don't hit the barrel.

This also doesn't have proper recoil lugs at the screws as called out by the M-LOK spec. Time will tell if this moves under recoil. However, with all that said, I wouldn't hesitate to buy again if needed.
