Following . Nice to see you chime in Erik!
That 760 with the 2100 tube looks awesome! That's the look I am going for. To do the conversion, all that is needed is the 66 pump tube and linkage. The piston is the same length as the 760. I am using the tapered (not flat top) valve since that is what came with the 760. I always remove the aluminum spacer in the valve and replace the stock valve spring with a longer one. Finally, I drill out the valve port from 1/8" to 9/64" for better air flow.
Does anyone have a recommendation for a "muzzle brake" vendor?
Here is a photo that shows the new look. The barrel is only 5" past the end of the pump tube, compared to about 9" on a standard 760. I think it will need an "air stripper" to complete the look. Thoughts?
