The end plate or sling mount will be peened again upon install, castle nut is good for reuse.

If it is the castle nut, is it staked in one spot or in all of them? If it's just one spot, just re-stake it.

Make sure you use a GOOD wrench, not one of those cheap spanner styles (one pin). Use the three pin wrench, you won't regret it.

I don't regret spending the money on this Brownells wrench after doing about 10 lowers so far.

Posted: 6/27/2012 11:30:28 PM Nice, I've done about 50 changes with the three pin with no issues, and still using it. The 4 pin is nice though. The 3 pin wrench can be got at JT for $12 or so. FWIW.
