Muzzle Brake

[A Guy Out West]

I’m brand new to the world of muzzle brakes, I recently screwed an American Precision Arms Fat Bastard onto my new Tikka Super Varmint. I am amazed at the amount of recoil reduction. I had my son video me shooting so I could see it work. The video showed a large gas cloud jetting straight back into the objective lens of my scope. Can’t imagine that’s a positive experience for the scope lens. Is this going to harm my scope lens? I’ve never heard mention of this, anyone ever have a problem from it?

Are the ports horizontal?

Yes.

Can you post the video to YouTube? I’ve never see gas come back to the scope before. A brake really is effective at mitigating recoil but they really do increase noise at the shooter.

 

[Eddie P]

Yes.

I can't see the orientation from that pic.

The ports are on the left and right. The small silver screws is the top. PM me your email and I’ll send you the video.

Let me see if I can remember how to do that.

It was forwarded to me in a text, can’t seem to be able to do anything with it other than forward. Pm me your email and I’ll forward. Perhaps you will know how to post it, I’m sure others want to see it.

Kid posted it to YouTube.

It’s hard to see exactly what is going on as the video is in real time. There is certainly the appearance of a circlular shock wave on firing but I think this is displaced air from the gases which will come out at right angles.

Personally I’ve never heard of any issues and I think you should have zero concerns. The scope will thank you for the reduction in recoil if anything.

A shock wave, That sounds like a good explanation. Glad to know I don’t have to buy something else. Thanks!

The gas cloud is not coming to your scope, the camera angle makes seem it so.

Regarding post #10, muzzle brake doesn't reduce the burden on scope, instead it puts far more stress to it. The peak acceleration occurs at peak (chamber) pressure, and brake is doing basically nothing at that time. But when the rifle and scope are already moving backwards from initial recoil, the brake introduce acceleration to opposite direction. Many a scope, including highest regarded manufacturers, have been broken with repeated fire on braked rifles.

Muzzle brakes work.

But trying shooting it of a bipod on dry, dusty, sandy, gritty ground. That gas cloud will drive all the sand and grit into your face. Most unpleasant.

Even better try and shoot it alongside other shooters on the range. Firing point will soon be empty. Given that you’re ear drums have taken an utter hammering, you won’t hear all their snide comments.

The blast is going to the side of you rifle not on the top as the brake has “shark fin” baffles. You can. Also tune it by removing the grub screws on the top which vent straight up and not back towards the shooter. You have picked an excellent product to be fair.

Do not worry and carry on

It remind me of the time I was on the range with my 7X64 it was the first time with that rifle. I warned the line, all had ear protection. But one unfor soul had a cochlea implant he forgot to remove. There were some expletives after my first shot

I have a " boss" system on my 243 Winchester 70, although the noise coming back to the shooter is certainly increased, it's nothing to what those to the side of you hear and feel! You have been warned

Try putting some tight clingfilm over the lens, I bet it ends up intact and clear of residue.

This little test will reassure you.

Thanks.

Great minds think alike.

Good to know! I don’t be putting any real expensive glass on it then. It’s really hard to see but if you watch the video enough, you can see the shock wave entering and bouncing back out of the scopes objective.
