Dave Baks goes for a heavy one in this video for Airsoft Obsessed, the ASG M60E4/MK43C US Ordnance Support Weapon. This the commando version with a full metal RIS front-end that allows the gunner to mount weapons accessories. The rear and front sights are adjustable, it comes with a steel folding bipod, and the 4000rd magazine is adorned with fake bullets.

The ASG U.S. Ordnance M60E4/Mk43 Commando AEG is available at Evike.com which provided the unit that Dave used in the video.
