Spike’s Tactical knows that when you work on a build you only want to work with the best. If you’ve carefully chosen the best parts, doesn’t it make sense that you should have good quality AR tools to work with too? Don’t struggle with a multi-tool that treats the castle nut as an afterthought or spend a chunk of your build time refitting a badly manufactured castle nut wrench. Instead, use the same quality AR armorers wrench that the good folks as Spike’s Tactical use at their own benches.

Spike’s Tactical Castle Nut Wrench is a 3/8 drive wrench head made of high quality 4140 Chromoly Steel treated with a durable phosphate finish. This is one AR tool that will do its job right out of the package, no need for filing or refitting. Spike’s Tactical offers this essential AR armorers wrench so you can rest assured that when you apply the castle nut to your buffer tube you won’t have to cope with a flimsy wrench that won’t do the job. It’s essential to properly tighten the castle nut on your AR. If it isn’t properly placed, you’re headed for disaster. Spike’s Tactical makes this crucial job an easy one with this handy AR tool.

    Very high quality! Built 5 AR with this wrench so far. No problem at all.

    This did the job, but i kind of mangled the ends of the male keys in the process. Rookie mistake, I'm sure - but this could probably be made out of something stronger. Feels comfortable to hold.
