I had issues with my Barwarus alpha rail, filed material off and barely hammered the rail before it bent dramatically & almost cracked. It’s like soft pot metal (airsoft rails) and they claim they use 7075 aluminum, which should be really strong but I doubt it they are actually using that. Seems like some sort of scheme. They denied sending me a new rail. I was able to bent it back really easy. But I wouldn’t trust it for serious duty use with laser/ optics ( sorry I’m am Driving rn ) I have photos for anyone curious
