Matador shroud vent mod=quieter
Ive been shooting my new R3(new reg version) 25 cal Long and cant help but notice the distinct blast of air out of the vent holes.
My R3 22 Long air release is barely felt or heard,but this 25 is blowing hard puff of air and the sound is definitely noticeable(mostly what I hear on shot).
The vent holes are same size on both shrouds as shrouds appear to be same( standard interchangeable part)
I know the 25 is pushing considerably more air and am wondering if slightly larger holes or more would be more efficient to venting additional volume(allowing pellet to leave baffle in a vacuum,increasing accuracy ) as well as larger/more holes not increasing velocity of escaping air(less noise).
After all compensators on PBs get more or bigger holes as caliber/power goes up.
Thoughts anyone?

That’s why I never drilled out the shroud..I was afraid of putting holes in the damn $2000 gun…and then I was afraid of not likening the outcome…so I learned to live with the sound it makes…
This evening I went to the hardware(lowes) store to look for scotchbrite pads but they look exactly like the green ones I have at home in the kitchen. So my next stop was to Michael’s(craft store) and found felt sheets and thin foam sheets. I bought one of each just for testing. When I got home I cut 2×4 of each piece and shoved them down to where the vent holes are. With the felt sheet, it was louder than if I had nothing in the shroud. It was a loud pop. No longer ppfff. I then tried to squeeze the foam piece in there but it didn’t move that well down the shroud so I took it out.
When the felt piece was in there though, I went into a guest bedroom and my wife was standing by the door. I asked her if this is loud. Pulled the trigger and she scream yes as if I was crazy for shooting it lol. She left. I was a little disappointed in the results too because I could tell it was really loud!. When I hold the felt sheet up to the light, I could see through it and see the light. Porous enough for air to go through. My guess is that the air came down the shroud, got too tight so it reverse and went out the front. Causing a louder bang.
Things I did to the gun today. Drilled pre-existing holes in the shrould with 3/32 drill bit. Drilled another row with same bit. Also drilled the baffle nut with the 3/32 bit. Every other hole in the nut like Demp. Not sure what else I could do. Since you guys(Hoot, Demp) got the long, maybe that works better? Anyone with R3 .25 STD have good results with this method?
Hoot knows what he’s talking about. His adult diapers have enabled him to sneek up on Oldgoat numerous times for a a quickie no matter how much Mexican food and margaritas he had the night before.
Porous foam works too. Almost any material that is porous, and allows air through it, will slow down the blast impact from the initial release and stop any sound from being produced by the larger vents.
All you are doing with the vents is allowing more air to be released at the rear of the shroud, take the excess pressure off the muzzle, and the “filter medium” whatever you use, simply slows down the velocity of the air going out the vents.
Rear venting makes a Serious sound difference!

Why not try a wad of fiberglas insulation? You can twist it to get the right shape and density. It should work.
Thanks for the tip guys, I just tried to squeeze in the green kitchen scotchbrite pad but it is a little too thick. I might try some coffee filters and see how that works. If not then I’ll go buy the scotchbrite pads at the hardware store.
Don’t forget the black felt pen.
Or try some airfilter from a vacuum cleaner. Over here almost all vacuums has a thin compact felt filter between bag compartment and vacuum motor.

The quote below should’ve been in the tutorial. I drilled my holes in the shroud and it was very easy to do. Like everyone said, go slow and then once the drill bit is stable you can speed it up a little. Pre-drill hole puncher is recommended on the second row or else it slides. My holes aren’t lined up exactly with the existing holes but looks good to me 🙂
Next step, find some scotchbrite pads.
Use this as the perfect excuse to invest in some more tools. The only thing I have more of than guns is tools. 😀
Hahaha Donny. Great response. I’m keeping your card though. Roar like Katy Perry and squealing. ❓ ❓
You get it back with first confirmed kill at 100yds. I took my regular open 19mm open-end wrench and just ground down the sides thinner so it would fit and give good leverage.
Don’t forget to use a bit of antisieze on threads during reassembly. As a matter of fact go through all bolts on gun and put a bit on them. It will make life so much easier as well as saving threads when you do work on it.
Yes it is and mine would do the same Brant. Luckily he was still sleeping. At 35, I am still scared shietless of my dad. I went through all of my regular wrenches but their width would not allow them to attach to the nut. I was afraid to damage the shroud thread. That was actually my 3rd adjustable wrench before I got it to work. The other two just couldn’t handle the resistance and broke.
You heard a squeal and slipped a nut? Is that an adjustable wrench? My father used to beat me like a step child if he caught me using one. 😆
First thing in the morning, all I could think of was Demp223’s saying I should give up my man card. I got out of bed went to my office, laid the gun down and padded it with one towel holding down the gun by the scope rail, another smaller towel wrapped around the wrench handle. I gave out a ROAR like Katy Perry with “Man card” still on mind and I heard a little squeal. That was the best squeal I’ve ever heard. I knew the nut gave in. Repositioned the wrench and turned it again and it moved some more. I then use my hand to unscrew the rest. The problem that I encountered with my gun is that the head of a normal wrench like the one Ed used in his video was too big. It would hit the thread on the shroud and the metal on the baffle. So I had to use a mini 6 inch wrench to be able to grab the nut. Definitely lacked leverage. See picture
Left hand pushing down on scope rail with forearm leaning on stock for leverage. Right hand on wrench pulling towards you. Just give it a good tug. It will come right off no problem. If not give your man card to wife and let her do it. 🙂

The drilled holes really don’t look that bad. I actually like it. Gives it more character. Even if it doesn’t work, I am not bummed about the way it looks. I was lucky not to have any runoffs with the drill as I was drilling. That was my biggest fear, leaving a silver streak in the coat.
Edit* UGMJ I could also say that about stripping and staining your close to 2k gun 🙂 That’s more of an overhaul then drilling these holes. Looking forward to seeing the final product on your stock though.
