Magtech is by far the best ammo I’ve shot through my 300 blackout. I prefer magtech in all my handguns as well. This ammo is fail proof and very accurate. It is sometimes a little bit higher than others, but to me, it’s worth it!! (Posted on 7/30/2025)

These things are great. After reading up on them got my first AR pistol in 300 BLK. Magtech 123 gr shoots inside the nine ring constantly, never a jam or misfire. So how come out of stock is now the rule not the exception? (Posted on 7/18/2020)

I bought this ammo after a Youtube video review of the Ruger Mini-14 in 300 AAC Blackout. The reviewer's Mini seemed to like the weight of these rounds so I thought I would give them a try, being that the price seemed reasonable. A trip to the range confirmed my Mini-14 300 Blackout liked them as well with 50 rounds sent down range with no failures. I am very pleased with this purchase. (Posted on 3/19/2018)

I ordered the 500 lot and didn't have a single malfunction in any of the rounds. I was getting 1 MOA groups at 100 yds with my Trijicon Acog so I can say I'm a happy guy. Will be buying again soon. (Posted on 10/22/2017)

Magtech 300 AAC Blackout was a decent buy, not great, my main issue with the ammo was 10 to 12 times the ammo casing did not eject properly and got stuck in the chamber. I ran through 500 rounds with a Sig MCX SBR. I also shot 100 rounds of 150 grain Blackout by another manufacturer and had no ejection problems. Not sure if it is the lower grain or the weapon itself (Posted on 8/10/2017)

Good Ammo and at a good price, I ran all of the ammo through a Sig MCX 9 inch SBR, only a few small issues 3 rounds did not eject and got caught half way in the chamber. But the ammo as a whole was good, I will probably another lot of 500 rounds to get a better fell for the rounds, so far no other issuses (Posted on 7/23/2017)

I shot all 500 rounds I bought through a 10.5" SBR using Magpul Gen M3 30 and 40 round mags. The ammo never had an issue and fired every time. I will be buying more at this price and quality. This is one of the best non-subsonic ammo for the 300 Blackout you can buy. I would hunt with this when the opportunity arises. (Posted on 5/27/2017)
Great bang for the buck!

Good ammo, works great,ran it through a brand new 8 1/2 inch SBR 300 Blackout with zero problems. I really expected something to go wrong but new gun mags and ammo all ran great. Oh and a great price on the ammo. (Posted on 4/11/2016)
