Strike Enhanced Castle Nut with QD Black

Specs

• Model Enhanced Castle Nut w/ QD
• Fits AR-15
• Black SI-AR-ECNEEP-BK Yet another first

Key points

• The SI Enhanced ECN and EEP stand out from the generic parts kit units in both aesthetics and function
• The steel castle nut has been lengthened to match the extended end plate, supporting more of the receiver extension's threaded area, and improving aesthetics
• The extended end plate features a Quick Detach sling swivel mount, pushed back away from the webbing of the primary hand
• This allows weapons manipulations in tight spaces and under stress, without the startling pain that can result from a pinched hand when using a sling attached to a standard, flat QD end plate
