What is the correct original rate of twist for M14 rifle barrels? Is it 1/12" or 1/11", I am not refering to the National Match Barrels but standard rack grade barrels.

Neither, it was a 1 in 10" twist.

The twist rate for the USGI M14 chromium plated barrel (drawing 7790190) is 1:12.

I have owned 2 M1As with USGI barrels. One Winchester and one TRW. Both were made in 1963. Both are chrome lined and both are 1:10 twist.

both are 1:10 twist.

the 1903, 1903A3/A4, and the M1 Garand ALL had 1-10" twists.. the M14 is a 1-12" like Different said......
