Upgrade your Leonidas or Leonidas Ti to the new Leonidas Gen 2!

This upgrade includes all of the Gen 2’s defining features, such as the 16.5″ overall length (1″ shorter than your current Leonidas), 1:7 twist Criterion barrel, and adjustable gas block. Simply purchase online, and ship us your upper with the receipt enclosed (or your order number), and we’ll rebuild it and mail it straight back to you. The Gen 2 upgrade will leave you with an upper that’s just as quiet, shorter, and lighter than your current one.

All barrel and silencer parts are included. Your original upper receiver, rail, bolt carrier group and charging handle will be reused. This upgrade is the fastest way to update your Leonidas or Leonidas Ti, so order today!
