XCR-L Mini Builder

Welcome to the XCR-L Mini Builder.  The Mini is ideal for making a rifle caliber pistol or short barreled rifle (all NFA rules apply) for backpacking or diplomatic protection.  Our customers say the XCR is best Modular Weapon System on the planet.  All XCR-L Models have a common Lower Receiver which is the serialized part to which can be attached a Pistol Cap (making the XCR a pistol), or one of our FAST Stocks (making the XCR a rifle).  All NFA Rules Apply.

This Builder is to help you configure and price an XCR-L using the Mini length Upper Receiver.  There are other builders for the Micro, Standard, and Competition length Upper Receivers and for our XCR-M Model.   You should check them out also.

The Mini Upper can be configured with the Gas Block “Exposed” (outside the Upper Receiver), or “Buried” (inside the Upper Receiver).   The advantage of the Buried system is that the Operating System (Gas Piston & Gas Tube) are shorter which allow the use of shorter barrels and lower pressure cartridges such as .300 Blackout (Most Subsonic .300 Blackout ammunition will even cycle without a suppressor in the XCR-L). The Buried system uses only the Type 3 Gas Block with 8 gas settings.  The Exposed System can use either the Type 3 Gas Block or the Type 2 Gas Block with 6 gas settings.  The gas settings on either are easy to adjust with the use of the tip of a cartridge to optimize performance.  In this Builder, the Mini Upper Receiver is labeled simply “Mini” and the Buried is labeled “Mini Buried.”

Please note that only the default options are shown until you click on an option.  Go ahead and build the XCR-L of your dreams.

Please also note that we can make your XCR almost any Cerakote or GunKote color even though we show only three here.  We can also make some barrel lengths not shown here upon request.

Every configuration covered by the Builder is production and ready to become yours.
