Great product great price satisfied customer!!

This is a great company! I have no dislikes it's what I ordered I definitely will order it again very good experience and no problems at all.

Good Ammo

Fast shipping and the ammo runs great. A little misleading "400 round with free ammo can". It's actually 2 smaller plastic ammo cans, each with 200 rounds. No big deal to me, but not really what I was expecting.

Winchester M855 ammo at a great price per round and features flat-rate shipping -- plus it comes packed in two free ammo cans!

Winchester M855 5.56mm's arguably your best all-around AR ammo that, for only $249 complete, fully 400 rounds of which can arrive to you via UPS in two very nice 2A Warehouse Mini Plastic Ammo Boxes. Hard to say no to it; in fact, I ended up getting two orders!

This product is just as advertised and in great condition

Rarely does one purchase exactly what they ask for online, but Gun Prime has yet to disappoint and always available to answer questions.

Good experience

I read reviews about Gunprime on a search site and there were some complaints about Gunprime and the vendors they use to fulfill orders. I didn’t experience any issues. They had a good price for today on WInchester 5.56x45mm M855K 62 Grain Full Metal Jacket Green Tip and they shipped very quickly. I received multiple updates all the way through delivery. I would order from the again, and in fact already did.
