I had a hard time deciding one what to write about first, the difficulties I had installing the Rainier Arms Switch handguard, or the success I attained with Gem State Armory’s Wrench. I guess for this one I will start with the problem that introduced me to one of the best wrenches on the market! So we were putting together a 308 upper and decided to use the new Rainier Arms Switch handguard which is made by Fortis MFG. in WA. The difference is minute, the Rainier version just has an awesome angled cut in the front similar to diamondhead’s handguard, but in a lighter fashion. The Switch handguard has a lever to lock the handguard onto the proprietary barrel nut that came with the handguard. This way if you wanted to change out handguards, you can. I don’t know why you would want to change between other switch handguards, so if any of you have an idea why you would, PLEASE comment and let us know! From what I gather, they had a previous barrel nut design that required indexing vs this new design which you just torqued the nut to spec and it was good to go. Where I ran into a problem was with the new barrel nut and the bull barrel (Rainier Arms 308 UltraMatch), none of my adapters or wrenches would fit! Here you can see the standard ar10 style pinned adapter wont fit around the barrel.   I contacted Gem State Armory (G.S.A.) and asked them if I had ordered the wrong adapter. Jeff, the Owner of G.S.A. contacted me to help me figure out what was going on. After corresponding back and forth is when we figured out that Fortis/Rainier changed the design and we were able to figure out the specs for a new adapter to work with the new nut and bull barrel.   Final Product! Adapter fits like a glove! Here I am starting to crank it down. I completed the install with my torque wrench inserted into the 1/2″ drive port. Now that we got the problems solved of torquing down the barrel nut, now we can talk about the solution bringer! The Gem State Armory wrench is made from...
