Thread: Muzzle brakes, Suppressors, and Accuracy

fitting both a muzzle break. or supressor means recrowning sometimes this is the real fix in my opinion based on experience with three rifles.

I have a muzzle brake on my JP AR. It is annoyingly loud but compared to other AR's I have fired, suppressed or without a brake, it is noticeably faster and easier to get a second accurate shot off.
The brake design is pretty generic on the JP. It is double baffle with parallel ports, but has a large surface area for gas to impinge on.

I would like to suppress the same barrel to form any solid conclusion as to which is better, but I suspect the break is way more efficient.

So are you trying to say that a muzzle brake or suppressor that isn't concentric and therefore not having an even gas flow around the bullet won't effect accuracy or stability? And that the air being pushed forward of the bullet as it travels down the tube and into/onto the brake/suppressor plays no part?

Provided any offset is small - as it should be for a correctly fitted brake or suppressor - and remains the same for all shots, then my thinking is that the effect on accuracy from a slight but constant eccentricity will be negligible.

My back of an envelope calculations found that the column of air in a 20" .308 barrel has a mass of 0.03 grams whereas typical loads for 308Win are 3 grams, so yes, again negligible.

I've read a few pieces that claim a small increase in accuracy from a suppressor because the air the bullet enters after leaving the barrel is calmer and less disturbed than it would be without the suppressor.

My quatro max is nearly done and fitted. I will be looking forward to testing it against my can on the RM. Not sure I can ever beat my last group with either mind you

As an alternative I found this bolt on muzzle brake made by Hinterland shooting Supplies. Have used it on my 300wsm and now on my 260. Has decreased group sizes and recoil considerably.... But shitloads louder!

I wonder if the insane cost and added hassle of getting a suppressor in America has much influence on those results.
Interesting that all 100 shooters used one or the other.

The thing with the PRS competition in the USA , is that you might be using a suppressor but if the guy next to you is shooting with a muzzle brake, you still have to wear ear muffs; so if you have to wear ear muffs, you may as well shoot with a muzzle break.
Remember that is quite a dynamic type of shooting where you are carrying all the shit with you during most of the day: ounces equal pound, pounds equal pain!

That break was designed for 105mm L118 Light gun

Yes, interesting between the two but one would think like all rifles, different rifles may like one better than the other. Was watching a vid on U tube before with a guy who had a tactical 7mm mag, had a muzzle brake which he liked and shot reasonable groups with it. He tried a suppressor to compare the difference, and even thou there was noticeable more recoil he shot far better groups with the suppressor than with the muzzle break.
On another side track, im thinking about getting a 7m mag myself. Will be used for open country, longer range stuff(not miles thou ). Even thou I know a 7m mag isn't huge on recoil, the less the better so was thinking when I get one I put one of gregs T2 brakes on. The question is, will the muzzle blast and noise be a issue if im wearing hearing protection?? Is a 7m mag with a muzzle brake be extra loud or be fine using the right hearing protection or is going the suppressor way the better way to go?
As im likely to be using it only for open country I have no problem wearing plugs or muffs when using it , or when I see game.

There is an easy fix, come up the range sometime, I have a brake testing 7RM, suppressor, brake & ammo, you can try them out

Best to go out the front of the range & lie on the grass, any structures around you can change the sound & blast signatures significantly

Cheers Greg, no rush but I happy take you up on that. Just want see what if feels like with a brake, ...I buy ye a beer

If your hunting with a dog or others @deer243 id suggest suppressor otherwise hearing protection and muzzle break wpuld do a great job
