.300 Whisper Pistol Build

[fireball168]

Looks neat!


I've drove a dead soft fishing sinker down the barrel in the past to stop me from drilling too far, then push it back and forth over the gas port to knock the burr off.


I've never been able to find a good drawing or print of the important dimensions on a gas system for a pistol length barrel.

Would you be so kind to post the dimensions from the barrel extension to the gas block shoulder and shoulder to gas port???
