XCR-L Micro Builder

Welcome to the XCR-L Micro Builder.  The Micro is ideal for making a rifle caliber pistol or short barreled rifle (all NFA rules apply) for backpacking or diplomatic protection.  Our customers love the small size and reliability of the Micro.

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

The Micro Upper uses a Type 3 Gas Block with 8 settings that can be adjusted with the tip of a cartridge to optimize performance.

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.
