The long barrel delivers maximum velocity from .223 Rem \/ 5.56 ammunition and the longest practical sight radius of the BL family, making it the go-to option for precision sport shooting at extended ranges. Like its shorter siblings it uses forged 7075 receivers and is hand-built in Bavaria, ~95% to customer specification.<\/p>\n<h3>Full 20&#8243; Lothar Walther Precision Barrel<\/h3>\n<p>The 20&#8243; barrel is long enough to extract full velocity from 5.56 NATO ammunition \u2014 particularly important for heavier 69\u201377 gr match bullets at extended distances. Lothar Walther&#8217;s LW19 grade keeps accuracy sub-MOA with quality ammunition.<\/p>\n<h3>Modernized A4 Layout<\/h3>\n<p>The classic A4 rifle silhouette is preserved, but with a modern 13&#8243; M-LOK free-float handguard instead of a traditional rifle handguard. This blends the sight radius and balance of a full-size rifle with the accessory flexibility of a modern rail.<\/p>\n<h3>Sport-Legal in Germany<\/h3>\n<p>The 20&#8243; configuration is approved for German sporting use and is popular among precision-sport shooters for its ballistic and sight-radius advantages over shorter barrels.<\/p>\n<h3>Hand-Built Bavarian Craftsmanship<\/h3>\n<p>Each rifle is built and hand-fitted in Oberland Arms&#8217; Huglfing facility with tolerances that consistently beat mass-production AR-15s.
