Fella's;

I've done the dis-assembly, reassembly on these before, but recently had cause to do it again. This most recent experience has driven home once again that if Miroku can figure out a way to Weird-Alice engineer something, they'll do it. And then refine it to make it even odder and more frustrating to work with.

The existing You-Tube videos that I found weren't much good, they don't cover the little tricks & fitments that are critical to getting the thing back together without hair loss, or resorting to strong drink. For instance, if you're not using your gun in the frozen north, a small dab of heavy grease, properly placed, will do wonders for anchoring the transfer bars in their slots. Then, when they're in those slots, you can then use a roll pin or other short, round thing (cut a nail with the Dremel tool) to align the trigger group slots in the bars. And do make sure the trigger group pin with the half-moon projections is properly oriented to go into their little slots in the receiver. Then there's the fact that if you should inadvertently trip the trigger, the hammer must be put into the cocked & ready-to-fire position before you go any further.

We won't talk about the Miroku T-Bolt's trigger on this forum. But, believe me, it's a beaut.

I always found a couple of pieces of one mil shim stock made life a lot easier. Good guns - I had three that never missed a beat, but I could never grow to love that bottom only loading.
 
Virginian;

They are good guns, I won't argue that in the least. Now then, please explain the procedure needed with the 1 mil shim stock. And, just for clarification's sake, is that one millimeter - .039 inch?

Yes, one millimeter. You just put one on each side like shoehorns and slide the trigger group in the receiver. Just go slow and easy. If you have enough clearance 1-1/2 or 2 mil are even better.
 
Luckily it's a pump and you don't really need to clean it that often for it to still work. Unlike, say the Ruger Mark 1-3 pistols.
