to make a long story short.had a bit of trouble with there 52grn hp 223 ammo in my new ar.only fired 7 of 100 rnds i had just purchased from them.relized i had an issue and asap emailed them about the issue.7 am monday my phone rings and it was a fellow gary i think was his name wanting to take care of issue.he offered to have my rifle inspected if i felt the need amd if any damage at all they would replace it pronto.well after a short visit about the problem we determend it was a none issue then he offered me free ammo.i declined the offer as no damage was done at all i thanked him and said i was not out to get anything for free but it was a nice jesture of them to offer.well today i opened the mail and there set a new box of ammo courtesy of them for my troubles.what a great company.oh yea it was corn cob media stuk in the hp from polishing.
