Spikes Tactical BAR2 by Johnno, Verified Owner, May 29, 2026
Great handguard! Large enough for an adjustable piston operated gas block, which is exactly what I needed it for. Fit and finish are exceptional.

sweet rail by Big Al, Verified Owner, April 17, 2026
Great rail if your looking for the tucked look. I'm using this in conjunction with a Dead Air Sandman x and its a match made in heaven.
