On social media we saw some discussion about how to prevent the Maccabee SLR's takedown screw from coming loose. I don't know whether it has a tendency to loosen or not. However I'm sure some folks are the belt and suspenders type or just want to be able to assemble it without cranking down the screw any harder than absolutely necessary. Conveniently TNA sells an enhanced pistol grip screw which happens to be the exact right size to replace the Maccabee takedown screw, and it comes with threadlocking goop on the threads so it's self locking. It's not permanent, just goes in tight!
