So, I know there is paper work and a wait for the tax stamp. What I don't know is what kinda parts it takes to put a folding stock on my P556. Please be specific with your answers. I'm a slow learner. links would be great. I tried to search around but it was hard going through that much info spread so far out. Thanks in advance for any help.
here's what I got to work with:

I used an ACE folding setup. Go to riflestocks.com, they are ACE.

It is three parts; the tube stock, the folding mechanism and the adapter. I picked the flush mount one.

I'm trying to figure out how much every thing will end up costing.

Yes that is everything that you would need, but you would not get the same result as I got. That setup has a castle nut, it would not be flush mount.

This part would get you the same result (flush mount)

Yep, Aurora front and rear sight.

And I use needle nose pliers to remove the plug.

questions for desert punk

I am in the process of getting ATF approval for my p556 to sbr. I heard about the engraving issue, and wanted to know how you did yours. I like the look of the pictures you posted of yours but wanted to know about the engraving. thanks for help.

What issues are you referring to in regards to the engraving?

What would you like to know about the engraving?

Also, if you wait a little longer, Aurora will be shipping more sights soon. :wink:

sbr engraving

I wanted to know what is supposed to be engraved, name, address only? and where it can be engraved, on the upper. Also, do you have the upper engraved before you get the tax stamp back? or can you send it to be engraved before you get the tax stamp back?

Name, City, State. Or, if you are transferring on a TRUST, you can put your Trust name on it instead.

In a conspicuous place that is clearly visible.

Most people engrave their 556 on the left side above the serial number as this is the best location as it keeps the gun looking clean and streamlined.

However you can if you choose to, engrave it on the right side of the receiver in the same location as the serial number on the left side, or above where the SN# would be also on the right side, or at the rear of the receiver on either side.

That is probably the best place to engrave it on the right side and is easier for whoever will do the work.

I would wait until I got the stamp back from the ATF before having it engraved, or if you have it at an FFL they can engrave it and hold onto it until your stamp comes back.

I hope this is helpful.

yes, that is alot of help and thanks.

I do have another question. What about on the left side of the upper where my upper has the "pistol only" can I have that wording ground off the receiver?

As long as you never plan to have your 556 SBR taken off the NFA registry and put it back into a pistol.

Though I would suggest having a gunsmith fill in the wording instead of grinding it down as you might weaken the rigidity of the receiver since it's already engraved in.

Sorry for the late response.

Overall length for the factory 556SBR is 30.1", length of barrel 10", that is what is on my Form 1.

Does the Aurora front and rear site co-witness when using the Sig red dot? Thanks. Can the sites be found by a simple search on line?

One other thing, I see that your stock is folding to the left side of the weapon. How is this locking up to the frame like it would to the right side? I do not have a pistol yet, but will soon. Thanks.
