There are three types of shooters. Ones that let somebody else fix things for them, ones that fix it themselves, and those that do it wrong. Which one describes you? Well, if you're going to work on your own AR-15, you're going to need to learn how to do it the right way. That means the proper tools and technique.

This Is The Right Tool At The Right Time

For decades, we have had to make do with an old-school armorers wrench. Now, thanks to Forward Controls Design we have the Joint Castle Nut Wrench. Sometimes, due to the design of the endplate, the average wrench just won't cut it. The joint Castle Nut Wrench combines design, strength, and precision for performance. Unlike some stamped metal wrench that may work if everything is perfect. The Joint Castle Nut Wrench is machined from 4140 steel and then heat treated. It is not only built to use, it is built to last.

Do It Right The First Time

When it comes to anything that can be dangerous, precision means everything. If you just crank down that castle nut by hand and stake it, you may live to regret it. To do it right, you have to use a castle nut torque wrench. The specs for an AR-15 castle nut don't just suggest 40 foot-pounds, plus or minus two, that is what it is. How are you going to get it right without using a castle nut torque wrench? What if by some miracle you can guess right on the torque but use a cheap wrench, slip and gouge your new buffer tube? Forward Controls will provide you with the right tool, get one and do it right.
