STAG/early S&W (very weak, but better than none, before using I would redo it)

Bushmaster (non existent staking, before using I would stake this)

Rock River Arms (they don't stake they blue Loc-Tite. I would heat and remove this stock, clean off the Loc-Tite reassemble and then torque and stake)

wooo! I'm going to go buy a colt m4gery now!

For all these drastic flaws you keep pointing out it seems like all the people who own Stag/RRA/Bushmaster have less problems than with the colt guns.

I would like to hear fom others or see info on how ofter the carbine stock nut backs off during normal use. I would assume that using an M4 full auto day and night might loosen the nut, but I don't know. Any comments? I only have 2 rifles (one additional in production) with collapsable stocks, so I have never experienced an issue.

Staking doesn't hurt.
I have always considered it a redundency to proper torquing but it doesn't hurt to have the castle nut staked.

What interests me is how shoddy the endplate fits on the rear of the receiver in the pictures that has a clear shot of this.
Even the Colt receiver model is a bit slack at the bottom and poor fitting here could contribute to a castle nut possibly loosening with heavy use.
Very interesting photographs.

If you use the cheap little GI collapsible stock wrench and an unstaked telestock, my experience has been that it will work loose frequently under semi-auto fire. I've had a Magpul for a while now; but back when I ran the telestock unstaked, I was retorquing at least every 500 rounds.

Wouldn't staking it make it hard to remove?

I've never staked the stocks I put on. I don't see the point of it. I check mine periodically and they've never come loose.

Gas key staking is important. This is not.

I can't get the nut loose on some Colt M4 stocks, thats with one of my Mongo sized Marines cranking on it. Had to cut it off with a dremel before repairing it.

Others come of realitively easy but others were staked with a jackhammer....

Anyone have trouble with a lock-tite'd one working loose?
