I'd use new ones. The old ones, being loose, might have gotten banged up. Not to mention, the threads are tiny, if they're torqued once - that's enough.

I think you can probably get away with using the old ones with no problems. But the screws are cheap, so it's no big deal to get new ones. Just my opinion. You can try to do it with the existing screws and if it works - good, if it doesn't, THEN get new ones. Just remember, you want to do it right and do it ONCE. If you don't do it right, then you'll have to buy a new key which costs $14ish...

Brownelles is the best place to order them since they have cheap shipping for items that only run $3...and they ship it out fast. They'll just drop it into a tiny padded envelope in the mail. If you buy new ones, you don't want to get it from a place that only uses UPS. Paying $8 for ground for $3 in parts is ridiculous.

DPMS screws are good..I've used these with success. They also have Colt screws (these really look better), but they are like $3something each. Colt ones are a little flatter on top, making it easier to stake since the metal of the key doesn't have to flow over it as much. If your key already has some stakes that stick out, but not enough to stop the screws, I'd probably get the DPMS ones if you choose to buy new since the Colt ones might not want to screw into the key unless the key is new.

Just to show the difference:

Colt left, (I think Bushmaster right)...you can see they're flatter.



There's also plan B -

Send it back to RRA and demand that a factory rifle costing nearly $1,000 should have a properly staked key. Demand they pay shipping both ways. I've had the key come loose on kit guns, but that I can expect for the low cost and the fact that it might be part of being a "kit"...but I wouldn't tolerate that on a factory rifle. The whole idea of buying a factory rifle is so you don't have to do that stuff. Put RRA's customer service to the test if you don't want to deal with this.
