Liberty Baffles

[FuzzyGrub]

For my upcoming Liberty 25 cal conversion, went looking for  a baffle option.  I found a seller on ebay that was doing 3D printed ones for Gauntlet and Freedom.   I found the seller very easy to work with.  Communication was excellent.  His baffles are caliber specific, but didn't have any 25 cal Freedom.  He was also very willing to adjust length to whatever barrel length / shroud spacing I needed.  I opted for the standard Freedom set of 4 baffles and barrel stop, + 3 additional baffles.  He was running prototypes as soon as we agreed.  The prototypes came out fine and quickly produced and shipped them.

They are designed such that the shroud end plug does not fully seat to keep tension on the baffles.  If this is an issue, can easily flat sand a baffle or barrel stop to fit your gun exactly.   I installed them in one of my 22 Liberty's for now.  Plan to do some side-by-side comparisons with a stock 22, when I get a chance.

Sounds super. Following and waiting for your results.

I was looking at those. Interested on how good or bad they work. Want to get some for my Liberty but don't want to waste my money on something that doesn't work.

Just what I was wondering/looking for.  I was chatting with another member about making baffles or insert for the 6" or so in the Freedom.  Curious how these work in such a small volume. 

Please post your results in sound and accuracy affect.  Thanks.

If ya need an air stripper let me know. Can print one for you. I went more of a k style baffle.

Rod, have you done any testing?  Does it achieve like Mrod sound level?  I have to admit that the Freedom isn't as bad as I though it was going to be but it is definitely louder than my Mrod.

[RDB]

No real testing, just by sound. Stephen did a test with Hajimotos baffles in one of his vids and only dropped 2-3db. Id say about the same. But it does change the tone from a sharp to a more muted tone. Perceived sound i think its referred to. Hush like adding a moderator? No. Better than stock? Yes.

On my 1st Liberty I used Mrod baffels within a section of Mrod shroud, slid into the Liberty shroud.  It was quieter, but not mrod quiet.  I then moved the shroud forward 1.75" and added more baffles and that made a good difference.  I'd say much closer to mrod quiet.   

These baffles wouldn't have the slight volume loss of the approach above, but expecting about the same results.  The 25 barrel will be 20" which is shorter than oem.   This gun needs volume in front of the muzzle.

Have you drilled holes in the barrel support under the shroud, to allow backflow to the entire shroud to help dissipate air?

I have not done that yet.  The large o-ring grooves don't leave much room between the barrel and them for drilling.   An air stripper/support would be better. 

[FuzzyGrub]

Rod provided me one of his 3D printed air strippers.      It is kinda like a Mrod air stripper, but much better designed.  It has four triangular areas to pass air back to the shroud and a cone in the center to help strip air away.  Very nice! 

Now, will test with this and then with venting the shroud, aka Hajimotto style.  Look forward to testing.

Rod surprised me with including a 3D printed barrel band for the Liberty.  Looks great and look forward to trying that on.

Very interested in your results as I have only drilled holes in all of the barrel supports for my Libertys & Freedoms.  I assume the stripper replaces the barrel support and the provided band is matched to the stripper. I do have all of the shrouds vented with at least 4 small holes about an inch ahead of the breech.

Thought I'd share what I got from Dave EZman when at the fun shoot this spring, noticed how quiet his Liberty was, told me it was a scotch brite pad held in place by a half inch spring from Lowes. I reproduced the same after coming home from the shoot and am still pleased at how quiet it is, cheap easy fix. I shoot out my family room window all the time at a target 30 yards away and it doesn't even frighten the birds on my feeder not 10 yards from the window, that or the birds are deaf.

Hi all,

I am the maker of the baffles in the first post.

Just for you information I took sound measurements of my 22 cal Liberty rifle at 12 feet the muzzle even with the end of the barrel. The stock configuration produced an average of 93.6 dB. The baffle set measured at the same point produced and average of 84.9 dB.

[FuzzyGrub]

FYI- Ran into some stumbling blocks with finishing up a Liberty.   I still plan to do these tests, but it will be at least a week out than planned.      

[larspawn]

I was wandering around the Dollar Store and found these two items.  I home rolled three and they fit perfectly in the Freedom shroud after I trimmed 1" off the scrubby pad.  I didn't take sound test but will try to later.  But it seems only slightly quieter.  What I've concluded is much of the sound is the ping and not the pop.  It really isn't that bad but given the size of the air tube I'm guessing there isn't much you can do to eliminate the ping?

[Stikkershokk]

Pulling the trigger when out of the stock, it seems that a lot of the sound is a spring ringing. Hammer spring i would assume, its in the action.

Liberty rings because there are two resonating chambers on the front.
My freedoms seem quieter because of the pump hardware. And a crosman baffle seemed to stop any sound coming off of the barrel, just like damping a bell.

I'd like to play with that idea tracker1955
How long was the spring you used?
I assume it overlaps the barrel
Does it go all he way in against the barrel support/spacer?

Thanks

Just installed a set of the baffles that GTA member hair makes and I can tell a huge difference. With the baffles both my liberty’s are more than backyard friendly not James Bond silent but a whole lot quieter. I put 22 baffles in my stock Liberty and 25 baffles in my hopped up liberty. Both were a great improvement. I do need to note that although both guns were what I considered back yard friendly before, when I went to install the new baffles there were no factory baffles in either gun.
