Elftmann Tactical recently released their new Ultralight Aluminum Stock. It weights in at just 5.2oz and attaches on an AR-15 rifle buffer tube via a clamp system. You can adjust the stock with just the turn of a knob, no clicking into the detent holes on the buffer tube. It retails for $134 and is available on Rainerarms.com.
“The ELF Ultralight Aluminum Stock is the lightest all metal adjustable stock produced today, weighing in at a trim 5.2oz. Innovative features include ease of adjustment over the entire length of the buffer tube and silent operation – no clicking into detent holes, a simple turn of the knob allows full adjustment and when tightened, it is rock solid with absolutely no rattle.”
