A sling is only as strong as the mount that secures it to your rifle. The M-LOK QD Sling Adapter, Heavy (MSQ-H) from Forward Controls Design is precision machined from 4140 chrome moly steel with an incredibly durable salt bath nitride finish to provide exceptional strength and durability. Compatible with your favorite QD sling swivels, the MSQ-H updates the existing design from Arson Machine with a stronger material, tougher finish, and a discreet Cygnus logo. At just 0.867 Oz., the MSQ-H is one heavy duty mount that won't weigh you down.
