This is not a new stuff, just search Excalibur MK1C, now named as 'Indian Assault Rifle' by OFB (sic)
It's milled receiver version of INSAS Excalibur, HD kwality pics already there on one thread.
It happened in a strange way, Very unexpected :) .. Was suppose to have dinner outside but instead went to a local exhibition nearby, Out of no where i spotted a black rifle, It had Unusual looks than what i am used to, On closing, i noted it was OFB`s stall, I didn't expected OFB presence...
