Optic cut it out - American Tactical Arms ATA19 Badger Stripped Slide with Optic Cut

Received the slide and put it together with the Cross Armory Standard Upper Parts Kit for Gen 3 Glock 19/P80 kit I purchased from Optics Planet. Very easy to assemble and quality products. The slide seems very substantial HOWEVER... it is supposed to be cut for the Vortex Venom Optic like the order stated. The screw holes are too small for the optic and need to be tapped to fit them.

Unfortunately, my tap broke when I was tapping the second hole and is now stuck inside the slide hole rendering it useless for the optic. If they say it is cut for a specific optic, it should be. I cannot recommend a product that doesn't say it will do what it is supposed to do.

Buyers beware!
