The BRN 180 Gen 3 upper receiver introduces significant updates over previous generations. Key improvements include a locking lever for the charging handle cap, a port buffer with a polymer piece to seal the action, and a non-reciprocating left-side charging handle. This Gen 3 model is compatible with any AR-15 lower receiver, such as the Colt SPR shown, and features an MLOK rail system and a four-position adjustable gas regulator, particularly noted for its utility in 300 Blackout configurations.

This video features Karl Kasarda from InRangeTV conducting a direct head-to-head comparison of an AKM and an AR-15 (M4 variant) in a mud test. The AKM, chambered in 7.62x39mm, experienced immediate malfunctions including failures to extract and feed. In contrast, a budget-built AR-15 chambered in 5.56x45mm, despite being covered in the same mud, successfully fired multiple rounds. Kasarda attributes the AR-15's superior performance in these adverse conditions to its more sealed action, which better prevents debris ingress compared to the AKM's design.

This guide details the mud testing procedure for the FN FS2000, as demonstrated by Karl Kasarda of InRangeTV. The test focuses on the rifle's reliability under extreme conditions, highlighting its sealed design and forward-ejecting mechanism. Kasarda, a recognized firearm testing expert, emphasizes the FS2000's ability to function despite heavy mud contamination, even with the ejection port open.
