To Make Travel

A friend of mine let me know that he was corrected by the Rav where he lained this past week on the following:

י:ב עֲשֵׂ֣ה לְךָ֗ שְׁתֵּי֙ חֲצֽוֹצְרֹ֣ת כֶּ֔סֶף מִקְשָׁ֖ה תַּעֲשֶׂ֣ה אֹתָ֑ם וְהָי֤וּ לְךָ֙ לְמִקְרָ֣א הָֽעֵדָ֔ה וּלְמַסַּ֖ע אֶת־הַֽמַּחֲנֽוֹת

He pronounced it וּלְמַסָּע with a קמץ under the ס. Kudos to the Rav for catching that. It's a big shul, too, so the בימה is not very close to his seat so that makes it even a better catch. If I'm not mistaken the correct pronunciation makes it a verb - to make the nation travel. However, the incorrect pronunciation would turn it into a noun, a journey, the singular of מסעי.
