I have 400rds of Lake City SS109 (greentip) & 100rds of LC tracer (orangetip), all on 10rd stripper clips in a 308 ammo can. It was originally linked in the m249 plastic box back when ammoman had them. It's been sitting in my closet the whole time.
I haven't tried the tracers (my club doesn't allow them), but the greentips still work well.
Not sure what is a good price now so I'm throwing out a number.
$100 + shipping. I accept paypal (add 2.9% + $0.30 if using cc) and USPS MO.
Thanks for looking.
