Homemade Flash hider question

Postby HeavyG-WV » Sun Oct 19, 2014 8:18 am

Hello All, I'm pretty sure I know the answer to this question but I'm going to ask anyway.
Is there any legalities involved in making your own flash hider? No suppresion is taking place, just a cool looking, screw on device.

Suppression quality is the real issue, aside from that, some states require it to be permanently attached, as in blind pinned or welded on (I think that mostly only applies to short barrels to maintain minimum length.). Barring that, in most areas there is nothing to prevent you from making your own that I am aware of.

A sound suppressor by definition muffles the sound of a report.

Even by as little as 1 db or less, which is not even discernible by the human ear.

With that said, if it doesn't, it's fine to make it.

Here's my PPFT with the homemade device. What do you guys think? Too Much? I kinda like it. It adds some weight but I'll see how I like it.

As long as you like it is all that matters.

I like the knurling.

Reminds me of the old time running boar barrels and barrel weights, the knurling is certainly a neat touch.

I like it. Does it have an expansion chamber in it, or is the bore of the device the same diameter as the barrel? Reason I ask is that an expansion chamber with venting can really reduce recoil and muzzle climb if the exiting gasses are properly directed. Also, helps define the device more as a muzzle break than a flash suppressor of just generic muzzle device.

Unless it is designed to make a barrel shorter than 16" the full legal length of 16", than i know of no State that requires muzzle devices to be pinned or permanently attached.

Thanks for the comments guys,

The bore diameter is 0.250" and the holes drilled laterally are 0.185" every 60 degrees around the circumference and every inch longitudinally. No expansion chamber. I hope to reduce the muzzle climb just from the weight alone. It's quite a chunk of aluminum. Probably won't do much for accuracy, I expect.

Well, I think you're right and wrong in your expectations.

Weight alone will not help reduce muzzle climb in the way you need it to. Sure, you can hand a cement block of the end and that will keep the muzzle down, but all that weight adds tension to your barrel, ruins and harmonic balance, and to your second point - degrades accuracy. Not only that, but as the barrel warms up, the accuracy will become more and more an issue, and point of impact shifts will be dramatic.

A quality muzzle break designed to reduce muzzle climb and/or recoil, will be svelte, and designed to be as light as possible while adding the attributes of recoil reduction and muzzle climb, typically by the use of an expansion chamber.

I do like the looks of the device. Very 1960's spy-like!

Well, it is neither svelte, as light as possible nor does it have an expansion chamber. But it sure looks cool. If it is a total disaster, I'll take it off for target practice and put it back on when the rifle is in the gun case. It'll be neat to get out and show friends that stop by. I'll try it out when I can and report back.

Thanks for all the input guys.

Well I took it to the range yesterday. As expected, the accuracy was greatly affected. I went from 1 1/4" groups in bone stock configuration at 100 yards to 4 1/4" groups with the new "muzzle device". It definately reduced the muzzle climb to almost nothing. Pretty neat experiment though.
