This video critically examines the BCM Enhanced Lightweight (ELW) barrel's suitability for suppressor use, contrasting it with the Government profile. The presenter highlights that BCM does not officially recommend suppressing ELW barrels due to potential Point of Impact (POI) shifts and increased group dispersion, information not clearly stated on their product listings. The video details how the ELW's lighter profile is more susceptible to heat soak, droop, and mechanical shift when suppressed, especially with heavier suppressors, leading to accuracy degradation.
This video from TFB TV puts the Heckler & Koch G36K's reported accuracy issues under heat to the test. Instructor Alex C. conducts a controlled experiment, comparing cold barrel accuracy with hot barrel accuracy after sustained full-auto fire. The results suggest that, in this specific test, the G36K maintained consistent point of impact and group size, challenging the claims of a significant 'wandering point of impact'. Further testing at greater distances is recommended for a definitive conclusion.
