Heavy-duty, ridged sling mount designed to keep the support hand behind the muzzle on short-barreled firearms, especially those fitted with extended magazine tubes. Installs under the magazine cap and secures the sling swivel via an integrated detent locking ball for positive retention during movement and recoil. Constructed from steel with a black parkerized finish for corrosion resistance and long service life. Accepts slings up to 1-1/4" (31.8 mm). Ideal for short-barrel, magazine-tube setups where maintaining a consistent, safe support-hand position is critical.
