Ordered 200rds of this to try since aac aint making ammo right now. Grouped good out of my 14.5 bcm. Fairly clean with shooting suppressed. Only gripe, each bag had 99 rounds in them so yall guys owe me 2 rounds.
Heath rider –
Looks like we owe you a couple rounds!
We’re glad to hear it grouped well out of your BCM and stayed clean running suppressed—that’s exactly what we like to hear.
We’ll get those missing two rounds sent your way. Appreciate you giving us a shot!

Update date on my 2 rounds short, this company is legit. 3 days later got a little bag with 10 rds in it. Now im in debt to them for 8 bullops. Shows great customer service, just earned a forever customer. I’ll come here from now on. Thanks guys. Also to add, this ammo slaps. Got average 2750fps out of my 14.5 mid and 2580fps out of 10.3 mk18.
