Liberty Baffles

Did you use the VELOCITY-19 code?  (chuckle)

I ordered 5 because I am not sure how I might modify them and I have 3 AGs on which I will eventually have some sort of LDC.

So far though, my best (to my ears) version was my first.  No baffles and VERY simple "design".

Of course, that may be because of my tinnitus and high frequency hearing loss.

Oh shoot!  (pun intended)
Did I miss an 80 cent discount AGAIN?

Fighting a sinus infection today, but did get all eight of the 23mm OD baffles wrapped with the scotch brite.  That should be enough even for the Mrod baffle swap out. 

[FuzzyGrub]

The baffles are 1" long, and was able to get three in the Liberty that has Rod's AS and vented shroud.  The shroud end cap is 1/4" from being fully screwed in.  Good enough to test.

The Liberty that had the Mrod baffles, were removed along with the mrod shroud section.  Five of Rocker1 baffles replaced 6 Mrod.  The baffles are pushed down tight to the Mrod AS.  This gun has the oem plastic shroud spacer, but it has not been drilled out, to allow air to the rest of the shroud.  The shroud endcap was able to screw in all the way.

Ready for testing.

Looking forward to your test results!

Still feel like sheet, but shot a mag through each gun and recorded.  The three Rocker1 baffles with vented shroud was most consistent at 91db.  That is the best so far with oem shroud position, by 1db.

The Mrod baffle replacement in a 22 Liberty, was also 1db quieter at a consistent 89db. 

When I feel better, will try baffle config options.

Played with the Trail baffles in my DIY LDC.   It did work, but it also did make shots POI erratic.   Just haven't spent enough time trying different positions with it yet.


I will have to play around with where and how I place it.   It may work best when installed inside the shroud, but I have not tried modifying it and using it that way... yet.

This is what the Trail Np baffles look like when placed into a Freedom shroud as far as they will go without modification.   I think I can work with that...  (smile)

It does fit OVER the barrel end snugly, but not secure enough to leave it this way.   My DIY PVC LDC will fit over it and keep it in place.   Haven't tried it yet, but will see if I can test it tomorrow/today/soon.  (chuckle)

[BackStop]

Yes!  YES!

I placed my "over the shroud DIY LDC" on with the baffles in the shroud as pictured.   The internals of my LDC keep the baffles in place.

YES!   Much quieter!  And the erratic POI behavior completely went away!   Shot it enough at 10 yards indoors that when I tested zero at 25 yards outside, in the rain, it was SPOT ON!

Total cost for 3 AGs was about $20 or so.   I can probably tune them a little more, but I don't think I am going to change much.   The hammer is louder than the muzzle, even INDOORS!

Mouse fart quiet?   I don't know... I have never heard a mouse fart.

[BackStop]

Dang!   Hit quote when I meant to hit modify...

I was going to add that my groups may even be a little tighter than before.   Maybe not...   I haven't tested enough to say for sure.   However, they are definitely NOT WORSE!

How much length did the DIY LDC add to the shroud?

[BackStop]

How much length did the DIY LDC add to the shroud?

So far, the shortest adds 7.5 inches.   I haven't played with anything shorter yet.   As I always shoot from a rest and almost always indoors, it doesn't bother me.

Do you have a source for tubes & end caps, or do you make your own?

I am using 1" pvc for the LDC tubes.   I have to wrap the end of the shroud with thin duct tape for a snug fit.   It isn't pretty, but it works for me.

For end end of the pvc, I simply use duct tape, shoot a pellet through it and then ream it a little bigger with a hot screwdriver.

Oh!
Essentially a baffled shroud that slips over for the rifle's shroud
That make a lot of sense, Kelly;
and offers some interesting possibilities such as varying the amount the ldc slips over your shroud & finding a way to leave the back of the LDC vented or open

Thank you

The Trail NP2 baffles are in the rifle's (Freedom) shroud and the PVC LDC slips over the shroud and keeps the Trail NP2 baffle in place.

For now, I have not changed anything on the PVC LDCs I have been testing.   I simply use them as is over the shroud as is.

The Trail NP2 baffles did not work well when I tried them in the PVC LDC and caused erratic POI shifts.   When placed inside the shroud, they work very well!

I have not tested the Trail baffles in the shroud alone, as that would require modifying the baffles (as some have done) and I don't want to do that.

[BackStop]

For those who simply want to make the Freedom/Liberty a little bit quieter, I suggest modifying the Trail NP2 baffles so they will fit in the shroud at Hawkeye51 and others have done.

It will work and you should not have a problem with erratic POI.   The POI will change, but it will be consistent.

It you want to get down to "mouse fart" quiet... then you MUST use an LDC.   The Trail NP2 baffles (unmodified) did make a big difference for me when placed in the shroud of my Freedom and held in place by the internals of my already tested DIY 1" PVC LDC's.

The baffles in the shroud made a big difference to my ears, but I still don't have a dB meter, so I can show any empirical data.

Materials used in my DIY PVC LDC's are:

1" PVC pipe

Thin duct tape

Scotch Brite (or generic) pads (Dollar Tree)

Small Pink hair curlers (Dollar Tree)

Cup washers (baffles) from grommet replacement kit (Harbor Freight)

Wool Felt (Hobby Lobby)... only recently testing with this.   Not much difference to my ears.


That is about as much as I can tell you without violating the forum rules.

Does anyone have the verified diameter/thread of the shroud end cap?  I'll be measuring tonight, but don't have a way to 100% confirm.
