Just incase anyone cares but SG ammo has the crazy hard to find Federal 5.56 tbbc load.(xm556FBIT3) It’s expensive @ 25.95 a box.
That’s actually about $10 cheaper than I have seen the .223 version for sale.
If you do a Google search for “reclassified XM556FBIT3” ammo you’ll find there is nearly 20 different vendors selling it right now. Apperently it just hit the civi market in the last few weeks but, SG ammo has it for about the cheapest soo far.
I bought 200 rds. a couple weeks ago from them and still haven’t gotten around to try any out yet.
