My buddy calls me today. He knows I am an M-14 nut, he knows I work on them, he knows I have quite a bit of knowledge. When he first picked it up I completely disassembled and inspected it with him to make sure everything was OK. Yet he purchases a Promag scope mount for his Armscorp M-14 and calls to ask me to put it on for him.
Drift out the stripper clip guide using the appropriate punch, fit up the scope mount, it seems to fit OK. Start the stripper clip guide mount screw, loosen up the front stabilizing screw, and start the side mount bolt with cam. Got everything lined up and started to tighten the side bolt using the combo tool. Turning in quite nicely it appeared, until it suddenly tore right out of the receiver.
It would appear that the bolt itself was too short and the threads weren't catching properly. Fortunately it doesn't look like it hurt the receiver, only the bolt threads. I suggested he go to the hardware store and buy a Grade 8 bolt just a bit longer than that provided and we could try again.
I sure wish people would ask before spending their money on this stuff.
