Frequently Asked Questions
Which AR-15 stocks is this sling plate compatible with?
The ProMag Ambidextrous Single Point Sling Attachment Plate is designed to replace the retaining end plate on standard mil-spec AR-15 and M4-style carbines equipped with 4-position or 6-position collapsible buttstocks. It is not intended for fixed-stock configurations. If your rifle runs a standard mil-spec buffer tube and collapsible stock, this plate should be a direct drop-in fit.
What type of sling hardware will attach to this plate?
The plate features integrated loops designed to accept hook-type single-point sling connectors, including common snap hooks and quick-detach (QD) hook fasteners found on most aftermarket single-point slings. It is specifically designed for single-point sling setups — it is not intended for two-point or three-point sling configurations, which typically require different mounting solutions.
Do I need any special tools to install this end plate?
Installation requires removing your existing castle nut and end plate, which typically calls for an armorer's wrench and a bench block or vise to safely support the lower receiver. The ProMag plate reinstalls in the same manner as your factory end plate. It is recommended to apply a small amount of threadlocker and properly stake the castle nut upon reinstallation to ensure it stays secure under recoil.
