I have a MG7 308 and it's probably my favorite can. Spooky quiet on 300 subs, sounds great on my Bergara 308 as well. I've shot it on my 5.56 guns and while it's still loud, it's definitely quieter than my Resonator K.

Love the size and weight. I consider this a K size can.
But if your looking for the quietest, length is your friend. I couldn’t be happier though. I’d buy another one.  Attached File |

I have a MG7 for my 9mm rifles. It works well so far. I have MG 10 for my 338 federal and it works great so far. My local suppressor shop had never seen a EA Vox or Rex until mine came through. That has no bearing on whether or not they are good cans. I would not hesitate to buy a Rex again if it fit my needs and budget.

My MG7 .358 is pretty decent with 300 blk subs. I would say quieter than Resonator k after first shot. The .308 version is probably very pleasant. Im gonna do a comparison of my Mg7 .358 and Res k on my battle rifle soon.

I love my MG7 in .358!
It’s my dedicated three lug can and gets use in my subgun and multiple pcc’s. |

The .224 MG7 has quite good advertized at-muzzle numbers on 5.56, but I don't know how it translates to at-ear performance vs the turbos. Maybe someone here has compared them. I'd be interested to know as well.

Quote HistoryQuoted: Strange that HB said that https://hansohnbrothers.com/shop/rex-silentium/silencers/30-caliber/rex-silentium-mg7-308/ Just to clarify. Hanson Brothers only recommended the .264 over the .224 because i mentioned that i also have some Grendel and they felt it would give me versatility and the benefit of less gas. The local shop is the one that didnt like K cans |

I've shot mine once on 5.56 and thought it seemed a little loud. But I didn't have my other cans out to compare it with and short 5.56's are always loud with .30 bore suppressors.

I’m waiting on a Rex 458, mainly to use on a 458.
However, they make standard mounts 1.375-24 and they make replaceable suppressor caps, so you can make the exit hole to match the caliber you are currently shooting. I can use a 22 caliber cap on my 458 can and it’ll be similar to a dedicated 556 can with a lot more volume. |

 I have MG7 358 on a PTR 9KT using a YHM 3-lug mount. Absolutely happy with it. I'd like to get a MG10 308 sometime. I ran a octane 45 on the 9KT for a bit. I like the shorter size the Rex provides and they sound the similar to me but I didn't try them back to back. I think the Rex is just a tad quieter. My hearing is far from calibrated so don't read too much into that. I'm happy with the build quality, the sound, and the compactness. Like I said, I want a MG10 in 308 some time. I already have a YHM resonator k. |

Numbers wise the Fullsize turbo would win easily. Turbo K vs Rex it will be hard to tell on a 5.56 SBR. My fullsize turbo sounds really good on a 11.3" 5.56 sbr, but I tuned the gas system alot as it was really gassy. For only sbr 5.56 use I would stick with YHM's turbo or K (better blast baffle), but for a multi use can the Rex will do everything you need and should be fine just might show more blast baffle wear. 5.56 sbr's are loud unsuppressed, are "good" with a k can, but better with a full-size can hearing wise. For less weight and length, turbo k or Rex would work great.

For what it's worth, I visited my MG7 308 in jail today for the first time and put it on an 11.5" 5.56 and 8.5" 300BLK. It was in a small indoor range and I had doubled-up ear-pro and no other cans to compare it to, so take this with a grain of salt, but I thought it sounded really good with 300BLK subs and it was a huge improvement over unsuppressed on the 11.5". I doubt it was hearing safe in that space but man was it massively better - more than just "taking the edge off" would maybe imply. It also feels solid and looks nice. A smaller bore MG7 should also be a few dB quieter on 5.56 - the .264 sounds like a good compromise in your case if you have a 6.5 Grendel too. I am sure the YHM cans are great too.
Basically, my guess is that you're not going to regret it either way. If you're going to be wearing ear pro anyway (you should), get whatever is available or will feel/ look right on the host. |

Pro tip: if you use your Keymo adapter that came with the naked Nomad, it looks like it was made for this Rex Slientium MG7.
  Also, the naked nomad looks better with a black Keymo adapter anyway. In my opinion.

I have a MG7 in 308 mounted with a key mo. I also have a Nomad that I recently shot it with. I was checking for POI shift between the Nomad and the MG7.
In getting this, I looked at it as a pseudo Nomad K when it came to exterior dimensions. Tested on two SBRs 9-10.5”, it was louder (no surprise) but not by a considerable amount. There was more back pressure with one rifle that isn’t adjustable, but has bleed off. Brass was getting tossed at 1 O’clock instead of 2 O’clock. The spacing on the baffles is much tighter than the Nomad. I also got a consistent POI shift of about 2” horizontally with two different hosts. Not a knock on the MG7. Could be the Nomad, MG7, or both she it comes to tolerances. I love the size as it is like a Nomad in K config or a Turbo in fat config. When I get the chance, I’ll run it with a YHM adapter and compare it to the Turbo. I’m happy with the size and the amount it suppresses. I don’t plan on hunting with it (where I wouldn’t have ear pro). It’s a range suppressor or good enough suppression suppressor. |

As a fellow Georgian, I'm curious what shop it was. I'm always looking to find another good shop to peruse. My LGS (GA Firing Line) has the Rex MG7Ks in stock pretty frequently, mainly the .308 and .358 from what I've seen.

Thanks for the info guys. I went ahead and ordered one today in .264. It will mostly live on a 10.5" 5.56 LMT but might get run on my grendel.
Of course now that I ordered it I see the Vox S and start thinking maybe I should have gotten that. Same weight, only .5" longer, probably a lot quieter and better materials. But it is $250 more expensive. Hope the MG7 fits the bill for me. Guess I could just get both.

At some point, we have to realize we are chasing absurd standards.
Yes, I know the suppressor buying process is absurd but very few of us buy one can to rule them all. Realistically, a vox S might be made out of the best material in the world but are any of us really going to shoot enough to the point where we are going to wear out a can? The answer to that is no, we are not. Maybe 1% of us will shoot out a can. That 1% can simply send the can back to rex and they will do what they need to do in order to get it back up to snuff. For the price, weight, materials and performance, the MG7 is a fantastic 5.56 can. No 5.56 K can is hearing safe and the ones that come close sound similar to the naked ear. They all take the edge off to the point where you're probably not cringing, as much as you're firing. Buy based around availability, weight, diameter, aesthetics or whatever the hell else may be important to you. Also, your shop poo pooing the Turbo K would make me want to find another less opinionated shop. The turbo K is a fantastic can for what it is. |

Just ordered an MG7 .224 from Hansohn, can't wait.
It's my first centerfire suppressor so it'll sit on my 11.5" HD SBR until I buy a dedicated can for that, probably a Turbo K, then it'll be dedicate to my 16" "SPR" build. My first 2 cans are still in jail, I need to take a ~150 day nap. |
