Those 'sneaky' Marines get everywhere .... in the Rough Riders!

It should be noted for CMP and most military matches, a Krag would have to have an 'issue' two-stage trigger, with at least a 3 pound 'let-off'.
(The free wheeling World of Dr. Hudson is long past).

Cleaning & de-greasing, judicious 'stoning', and proper lubrication, will likely improve your Krag's two-stage trigger.

IMHO - A better quality 'fresh' trigger-spring would likely help improve smoothness.

For 'Sportered' Krags, match rules are irrelevant, "have at" with human ingenuity!
