To best meet expected turnaround times for orders, MSAR has temporarily disabled the online ordering system. Orders may be placed by calling 814.363.9260 and speaking with Sandy. Because inventory changes daily, the list of available parts below may alter slightly.
*Please note that in order to remain compliant with firearm laws, not every part will be available in every state. Also parts not listed online (like the E4, or suppressed barrel) must be purchased directly from a dealer.
