Browning BAR Type 1 And 2 Mainspring Guide, Right Or Left

In 1969 Browning started using two digits for the date of manufacture:

M=BAR High Power Rifle

This was then followed by the serial number beginning with 1000.

Example: 69M1000 = A 1969 BAR High Power rifle with a serial number of 1000.

M=BAR High Power Rifle

In 1975 Browning standardized its serial number identification which it followed until 1998.

1. BAR Type: 137=BAR High Power Rifle
2. Date of Manufacture is a two digit code:
   Z=1, Y=2, X=3, W=4, V=5, T=6, R=7, P=8, N=9, M=0
3. Serial Number beginning with 01001 at the start of each year.

Serial Number Example:
