Sig Sauer LE/Military MCX 16" Caliber Exchange Kit - 300BLK
For the ultimate in versatility, SIG SAUER is pleased to release SIG MCX conversion kits. With a single Torx bit, an MCX owner can change caliber and barrel length in less than a minute. This 16", 300BLK kit includes a complete barrel assembly, installation instructions and a .300 BLK warning card.

SIG SAUER offers upper assemblies and caliber exchange kits in various barrel lengths. All NFA rules apply to installation of these upper assemblies to lower receivers and caliber exchange kits to upper receivers. Upper assemblies and caliber exchange kits with barrel lengths less than 16 “may only be affixed to lower receivers which (1) are not recorded as a rifle lower by the manufacturer and do not have a stock attached to the lower receiver or (2) registered with the BATFE as a short barreled rifle (SBR).

Note : Please check with your local and state municipalities for any further regulatory requirements. It is your responsibility as the buyer of these components to make sure you comply with all NFA rules and applicable laws.

Note: Items marked as Special Order are ordered from the manufacturer. Being a manufacturer direct dealer, we are dependent on their warehouse inventory and production schedule. While most Special Order turn-around time is about 30 days, some may take a lot longer based on manufacturer availability. Your card will not be charged until the item ships.
