WHAT HE ^^^^^^^ SAID. For the record, I think someone here happens to be looking for one of those knobs IIRC.Put the hammer away!!!
The knob and the piece it screws into are from an SAI gen 3 mount and are useful to somebody so don't destroy or discard them. The piece that the knob is screwed into replaces the stripper clip guide and slides from left to right into a dovetail. It would need to come out from right to left however there is a pin that needs to be backed out first. If you want to go to a stock USGI configuration you would install a stripper clip guide to replace the piece removed. Or just leave it as is (without the knob). Either way tapping the pin out must be done carefully and in the right direction. Best to get a book detailing disassembly and reassembly of your weapon before tearing into it. Clint Fowlers book would be a good...
No hammer, please!
Yea, we missed having some fun with that one at the OP's expense.I was waiting for someone to say it was the speed dial.
Turning it clockwise would take you up to full auto at about 900 rounds per minute, . . .
Turning it counterclockwise would lower it down to about 60 rounds per minute, . . .
But nobody said that........... USN3
May God bless,
