Strike Industries SI-AR-ECN&EEP-BK/AR Receiver Enhanced Castle Nut with Extended QD Endplate

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.

Due to numerous factors that take place during the anodization process, the color lines from batch to batch of a certain product may vary.

Torque: Do not exceed 35 ft/lbs (47.45 nM) for the castle nut

WARNING:

• Before every use, always check proper function of your QD mount and any wear and tear from use
• Always have your weapon in the SAFE position when not being fired
• Always follow all firearms safety rules and never point your weapon at anything you are not willing to destroy

Required Tools: The castle nut was meant to be installed using an adjustable or fixed spanner wrench. A traditional Ar multitool or wrench can work but may cause damage to the castle nut.

Note: Due to dimensional tolerances between some manufacturer's receiver extension collar lengths and differing amount of true threads on various buffer tubes, some may experience difficulties installing.

Package includes:

• 1x Enhanced Castle Nut
• 1x Enhanced End Plate
• 1x Warning card

Features:

• Aesthetic upgrade
• Centrally placed QD for right or left hand sling use
• Easy drop in installation
• Simplified installation of takedown pin and detent via set screw.
• Compared to a standard castle nut and end plate, the fully collapsed position, with most stocks, is eliminated in order to create proper clearance for the QD socket.
