Using brake after buying a suppressor?

[Allen One1]

I'm in "the Process" of purchasing my first suppressor which will be used primarily on an extended range 6.5 Creedmoor. Normal work area is from 600 to 1250 yards mostly from a bench no PRS stuff yet. For a mounting system I have been considering the Area 419 suppressor mount and their brake, also would buy a brake or linear flash suppressor from Area 419 so that the suppressor could be put on my AR for fun. Thought being that when the suppressor wasn't on the gun I would have a brake or flash suppressor on it.

Question: After purchasing a suppressor do you ever switch back to the brake? I know the POI will move as least a bit so that creates an issue that you would need to allow for.

It would save money if I just purchased the suppressor mount and add an adapter and thread protector for each rifle. You lose some options but does it really matter is the brake going to end up unused?

Another option would be to buy the suppressor mount, 5/8-24 adapter and the linear flash suppressor with 1/2-28 adapter.

In my experience, most people don't want to go back to loud if suppressed is an option.

Area 419 is solid. I wish they offered a muzzle device with an integral brake, though. Brake mounts generally improve suppression, and also reduce blast baffle erosion.

This. I have a can mounted on an AR. The only time it gets removed is for a rare function test of some random ammo load.

I also have a slew of cans from the very man I just quoted that are still pending. When those clear they will also be more or less permanently mounted to their respective guns.

I never could stand muzzle brakes. I'm even less tolerant of them now that quiet is an option.

Unless your AR is a 300BO, you will probably not care to shoot it suppressed. They are just too loud to be fun. Unless you just want to look cool with a can on your AR, then it makes sense.

Nonsense. Just because they're not hollywood quiet doesn't mean they're not better that way. Ears are still a really good idea, but the combined reduction of a decent can + ear pro is gonna be 50-60 dB. Even without ears, on an outdoor range, they can be tolerable for a few shots (rifle length gas can actually be quite pleasant)

This my a 7.5" 5.56 upper with my 5" Five By Five can, which meters 140.04 dBA on a 10.5" upper:

It is just a standard 5.56 piston gun with an 18" barrel. I'm too old to look cool anymore so that is out. I would love to put a 300BO upper on it though. I know it isn't going to be "quiet" but it will help some and I always wear ear pro at the range I shoot at, rarely is everyone going to be suppressed. Since I will already have it for the 6.5 it makes sense to me that I would put it on the AR on occasion.

Aren't people trying to load subsonic ammo for .223 that seems like a tough task to me?

 

[MCFLYFYTER]

I guess we are all different. Personally, if I have to wear muffs, I'll just take the can off and have a shorter cleaner gun. If it's not a subsonic 300BO, I'm just not really into suppressing my AR's. For the record, firing a few shots before your ears bleed is not hearing safe, it is doing damage in those few shots.

To be fair, I typically shoot under a wood roof, and a suppressed 16" 556 makes my ears hurt first round.

I thought about doing that and just bought a can for most of the guns that can take them.
The only ones that still gets passed around like a duby is rim fire cans.

I thought if you set up a gun for 500 yards plus you don't change stuff around when you get it where you want it?

You do know what I do for a living, yes?

I own a B&K 2209 with all the requisite hardware for metering gunshots. I'm not speculating about what is or isn't technically safe. An AR with proper gas flow for running suppressed will put down mid-high 130s dBs at shooter's ear. That's under the OSHA 140 dB impulse noise threshold. Most pistol & carbine length systems need an adjustable gas block to get there, mid lengths are hit & miss, rifle length is generally fine with fixed gas. Op rod guns are a different story, usually over 140 at ear regardless of can or gas settings due to piston pop.

FYI, .300 blk subs through an AR will still be mid 130s at ear if the gun is actually cycling.

If that's the case, I'm going to ditch the 300. A 10db difference should be barely perceivable. How short can you go on a 556 and still be close to 300 subs?

Decibel reduction is on a bell curve (MachIV has the numbers but it's something like a doubling for every 3 dB). 10dB is a huge difference.

I was thinking about it backwards, but inadvertently proved my point. 556 is significantly louder than 300 subs.

I have 10.5" and 11.5" AR's in 5.56
Without a silencer they are obnoxiously loud. As in dirty looks from others on the range.
With a silencer, they are quieter than an unsuppressed .22 pistol. Others on the range ask "is that a .22?"
