question?

[magdude]

i have a question about those tourney caps for you automag. what do they do for your gun and where do you put them?
thanks

the terny cap screws on the velocity nut. it has set screws to make it whare the velocity nut cant vibrate out. and it makes it whare you cant adjust the velocity without tools. which is why it is a turny lock.
