So, much to my surprise, someone mentioned that they had an old KNS Hammer cage but that they don’t do any gunsmithing anymore. And, he was willing to sell me his. So, I’ve managed to replace my irreplaceable set.
In the meantime, I had ordered a couple of other tools and this eve, I did some testing after assembling my replacement Strike Industries AR Trigger Hammer Jig.
Regardless of how a hammer is installed, KNS Hammer/Trigger Guide Pins are always useful, as are slave pins.
So, the discontinued KNS Precision Hammer Cage is still the easiest one to use, hands down.
The Superior Hammer Install Tool is next in line. It would have been my go to tool if a replacement Hammer Cage hadn’t miraculously become available.
The Hammer Handle is, in my opinion, a distinct third. You still have to deal with the spring pressure while maneuvering the hammer into place. Without the pointy KNS hammer guide pin, it still would have been far more difficult. The other two options at least take all the spring tension off.
But of course, one is basically unobtainable, and the other is expensive as heck…
Anyway, my opinion is worth what you paid for it…
