Tough Zytel nylon construction makes Thermold magazines incredibly resilient. Works with any weapon that accepts standard AR-180 magazines.  This 30 magazine has the ability to extend its body in order to accomodate 45 rounds.

Thermold Magazines unlike metal magazines, won't jam because they're made with Zytel Nylon that resists heat, dirt, and rust.  They are dent resistant, self-lubricating and as such these magazines are completely noncorrosive.   Made in the USA.
