India had a parallel evaluation program going on for the selection of a Close Quarters Battle weapon during the India MCAR evaluations that I have written about here previously.
As part of the CQB evaluation, Colt submitted LE6945 carbines that did not have bayonet lugs. India wanted to maintain the bayonet capability on their CQB weapon so Colt proposed this bayonet for the program.
The bayonet uses a section of 1913 rail for attachment instead of a bayonet lug.
More to come on this soon.
