The advantage of the LE6940 is unmatched. The LE6940 displays fresh ingenuity with a Magpul MBUS backup sight and a folding front sight for enhanced optical solutions and four rails positions for mounting accessories. The patented one-piece monolithic upper receiver incorporates a continuous Mil-Spec rail from the rear of the upper receiver to the front sight. This feature affords unmatched repeatability for mounting optical systems, not found traditional handguard rail systems. Designed with accuracy in mind, its true free-floating 16.1” chrome lined barrel provides the enhanced accuracy necessary for long-range shooting.
