What Customers Say
Customers rate this Magtech 300 AAC Blackout load 4.72 out of 5 across over 216 verified reviews and growing.
Turn your rifle into essentially a pistol caliber carbine with this load. Great for suppressed use but I use it for when the lady comes to the range with me. Very low recoil/blast compared to full power ammo. Cycles good to in my PSA 8.5” pistol length upper.
Eric T.
Took just a few rounds to dial in the gas block, but after that I've put almost the entire 1000 round box down range without a single issue. Not the cheapest ammo around, but I've always had pretty good luck with Magtech.
Jason M.
Great shooting ammo that performed very well in my .300 Blk AR pistol (10.5"). Fired suppressed, cycled flawlessly and grouped very nicely at 50 yards! Quality ammunition that I will look for again!

About Magtech 300 AAC Blackout
Magtech 300 Blackout 200 grain subsonic FMJ ammunition is designed for shooters who want a factory-loaded 300 AAC Blackout subsonic option from a well-known ammunition brand.
