Tailhook MOD 2 takes the pistol brace concept to a whole new level with it's ability to telescope the length. The key to this is our Patented proprietary telescoping latch mechanism giving the user 5 positions of use up to a 12.75" LOP. Combine that with the also Patented brace functionality and you have the new king of the market. The brace is injection molded out of reinforced polymer for rigidity and strength. It provides the perfect balance between size, weight, comfort and rigidity that everyone has been wishing for. A heavyweight with features all at featherweight mass, the 7 ounce* Tailhook MOD 2 is the clear winner. As with all it's siblings, the MOD 2 uses the same fold out arm to create the support shelf that inspired the Tailhook name. This counteracts the muzzle weight of your favorite large handgun. The telescoping feature lets you find that sweet spot for balance. As an added feature, the outsides are smooth for comfortable cheeking. There is even a web sling loop.Included in the package is the Tailhook, proprietary receiver extension, castle nut and back plate.Remember that when this is installed on a pistol, it does not change the classification of the pistol with correct intended use. But recent ATF opinion states that using a pistol brace as shoulder stock could be considered manufacturing a rifle.*estimated weight without buffer tubeCLICK HERE to: Download the ATF Approval Letter
