Halo Reach Recon Helmet Question

I am wondering, if you put your recon helmet on another xbl gamertag, then try it on a different one on the same console, will you be able to have the recon on both gamertags?

It being a single use code, would leave you with a no for an answer.

Well my dad says he wants recon and I get the chest piece but I told him about the advantages of the chest piece so I get recon now =3
