Today I was checking out some accessories and ran across the GG&G Agency Sling Adapters. They come in 5 different configurations; Rectangular Right Hand, Rectangular Left Hand, Rectangular Ambi, Quick Clip Loop Right Hand and Quick Clip Loop Ambi.
The feature that was different than most rear sling adapters is that you don’t need to remove the buffer tube to install them. You just remove the collapsible stock, slide it onto the buffer tube and tighten the adapter over the castle nut.
Below is some information from their site.
The Agency Rear Sling Adapter For Collapsible Stocks offers the end user a more consistent fit than our earlier version. Some of the recoil tubes being produced are smaller in diameter than the originals or Mil-Spec units. With our new design securely fastening onto the castle lock nut, various size recoil tubes are no longer an issue. In addition, the new design does not interfere with the charging handle operation, even the larger units like the Gas Buster. The looped versions are specifically designed to accommodate the HK style quick clips or snap hooks.
The Agency Rear Sling Adapters are available in looped right hand, looped ambi, right and left hand rectangular and ambi rectangular. The rectangular versions will accommodate slings up to 1 1/4″ wide. All are manufactured for professional use from 7075 aluminum alloy and Type III hard coat anodized to meet mil-specs. A 9/64″wrench is included for your convenience. Sling mounts and side sling adapters are manufactured in the USA at GG&G’s Tucson, Arizona factory.
The Agency Rear Sling Adapters were developed because certain government agencies established policies indicating that if a tool needs to be used to remove a part of the weapon to install a new accessory it cannot be done unless the gun is sent to the agency’s armorer or gunsmith for the installation. This caused a major problem for some agencies looking to update their weapons do to time constraints and the absence of local agency armorers. The GG&G Agency Rear Sling Adapter only requires that the rear assembly of the collapsible buttstock be removed. No tools required. The stock sling adapter then slides over the tube and, once in proper position securely tightens around the castle lock nut as shown in the photos.
