AR-15 pistols seem to be getting more popular these days with most major AR makers jumping in on the bandwagon. Accessory maker Damage Industries just released a pretty neat AR-15 pistol part. Their new AR-15 pistol buffer tube includes an attachment point for a QD sling swivel. It’s made out of 7075 billet aluminum with a 1.250″ outside diameter and is hard-coat anodized to Mil-A-8625 type III. The main feature is the limited-rotation QD Sling Swivel Socket at the end of the tube. It can be used with standard length carbine buffers and springs. It retails for $28.45 at Damage Industries, the QD Sling Swivels are sold separtely however.
