Hello, I have searched and read through many of the staking posts and associated pictures. The one question I have is if I want to improve the staking on a Stag BC that currently has the top"chisel" marks and I have a staking tool that will stake from the side can it be in the same spot as the chisel mark? It just seems like there is not enough metal where it has already been top staked and my attempt will just chew the the key up. Thanks for any help.
Pics?
Take a look at page 3-28 of TM 9-1005-319-23&P. It explains the field staking method.
Great guide thanks.
My camera is killing me close-ups are a no-go. After some more reading it looks like I should be OK, my concern is soft steel that won’t just “push” into the screw heads I just don’t want the ends is get jagged and chewed up and not accomplish the job.
Remember also that if you displace metal up, file it down.
If you displace metal out and in widening the key, file it down.
That includes on the little step at the top of the key.
My issue M4 has the “field staking” method on the bolt heads. In fact I think most of my men have theirs staked on that way as well.
There was a bit of metal displaced when I did my Bushmaster. I didn’t think that if left it would cause problems?
Yeah, I don’t know for sure but was taught that and it doesn’t seem like a bad idea, especially on the sides and is pretty easy to do.
On the top it seems to me that it would be within the channel on the charging handle and not really come into contact with anything, but if you look at the page in the manual linked to above it shows a maximum height to which the metal can be displaced.
There is also a diagram referring to “Surface A” although I don’t see anywhere what they want you to know about “Surface A”.
To me it makes more sense to make sure the sides of the key are smooth so as to not wear too much in the channel in the top of the upper receiver.
