I have an a300 UP with an aimpoint t2 on the scalarworks mount and within the first 20 rounds of birdshot after mounting it came flying off, I used the correct loctite, torqued properly. I just had the gun re drilled and tapped for larger screws and used the same mount again correct loctite and properly torqued and it stayed of for about 70 rounds of 00 buck, slugs and bird shot, this time I had used a paint marker on the screws and monitored them the whole time and checked to see if the dot was loose, the very last round I fired before leaving the range the dot came flying off again, screws hadn't backed out, they ripped right out of the reciever, I cant figure out what im doing wrong, ive seen many of these guns configured this way on here but I haven't heard of anyone else having this problem. I was thinking about getting the new vortex viper enclosed red dot and trying that out.
