AR-15

So True!

Where\'s the bayonet in that photo?

Here\'s mine. We\'re not allowed them in semi, so mine is straight pull only. With 5.2g of Trailboss behind 62g FMJ, you can hear the firing pin and the recoil spring rattle and that\'s it. :-)




The pink ring that screws onto the barrel actually has 6 holes spaced around it to let gases back into the relex section

Wow, I have never seen baffles that look like those. They look even more difficult to manufacture. Is it quiet enough to shoot without ear protection?

These baffles are called K baffles. They are a fairly common design in the silencer industry.


There\'s a lot of information on silencers at silencertalk.com. Most people dont realise you can own silencers in the US but you can. You can also manufacture them - you need a $200 tax stamp and thats pretty much it.

This rifle is very hearing safe. I really can fire it and just hear the firing pin hit the round and as the recoil shakes the gun, you can hear the main spring rattle. If you\'re shooting at a near target you can hear the round impact as well. Even with full power RG it is comfortable to fire without ear protection. ;-)

Hi Pmercer
 I am curently sitting on my ATF Paperwork for a 5.56 nato suppressor. Last year I made one to 22LR. I tryed it on a 22LR bolt gun and, like you said, all you can hear is the firing pin click and the bullet hit the target. I\'ll post a pic of a baffel later. Do you have a drawing for your baffel?
Thanks

Good stuff. More people need to make silencers. Over here in the UK, its just a case of asking our FEO (Firearms Enquiry Officer) to add another one onto our licence. Its about $25 to make a change to my licence, so I normally add a few rifles and a few silencers at a time. ;-)

I\'ve got CAD data for the whole silencer. I\'ll load it up tomorrow hopefully and get a few screen dumps with dimensions. If you want the .stl files of them emailed to you, let me know.

In the mean time, have a read:

Silencers have sure come a long way with mouse holes and dater holes. I can remember when fender washers and metal screw on bottle caps were used in some types of silencers. I read about a .223 silencer for the AR 15 that had a rear chamber portion that had a vent to the outside for releiving some of the high pressures before the gasses went through the baffles in the front section.

Hi Bruski & Pmercer:  I\'m glad you you two have brought up this subject because it has spured me to complete my suppressor. I have had the paper work back for a couple months. I think everyone should *LEGALLY* build one. They are not hard to build. The baffels you showed sure are a different design. I have heard this design fire on a AR15 and you hear sonic crack and the impact of the bullet against the target. It\'s amazing how much noise the bolt makes when you suppress the muzzle blast.  The baffels are 304 stainless. The spacers, the tube, and the ends are 6/4 titanum.

These parts are straight off the CNC and I haven\'t even deburred them but thanks to you two  I\'m going to finish it up.
P.S. This design is rated for full auto fire...  Now I need to get something full auto.  :roll:

Hey R-R. Those parts are looking good. Are they Stainless? Are you welding them together or are you making it a take down can?
I wish I had access to a CNC!!

It\'s amazing how quiet you can get rifles. The best thing to silence is a bolt actioned rifle. Anything semi/full auto makes a lot of noise in comparison.


Here\'s some dimensions for my K baffles. This image has a grey rod in to represent a milling bit. This makes two cuts on the baffle.


Here you can see the mousehole.


Ideally you would fix these baffles on top of each other in the same orientation.

Pmercer The baffels are 304 stainless. I\'m planning on welding it together. I have been shown that you can wash them out with proxide and vinegar. Seems to work well!

Excellent news on the material. It\'ll make a nice long lasting silencer. Initially I didn\'t plug weld all the baffles in mine and after a while the baffles started to crush down a bit and then act like a jack hammer on the other baffles. In this version, I plug welded all the baffles in place - something to think about if you hadnt. ;-)

I really wish suppressors would be legal where I am.  Would make shooting more enjoyable not having to wear ear protection especially at indoor ranges.

I really like the the design from Silencerco, where the baffles and mounting body are all one piece.
This one is for .22 LR but I imagine the idea could be scaled up to work with centerfire rifles.

Definately need a CNC to make one of these.

Or lots of patience!
