to vent or not to vent. that is the question
there seems to be some disagreement here about whether or not vented bushings decrease the noise of an Airforce rifle. my question is- do you think it helps and if so, do you get a further reduction by venting BOTH bushings. i vented the front bushing on my Talon SS with a Tony Tunes shroud and 18 inch barrel. should i vent the back one( the one near the chamber) as well? i honestly can tell that venting the front bushing did any good but maybe it did.

People the size of the ports in the frame make a big difference on the sound.
Big holes are a no no
Small holes are better
Just like a woman 🙂
Make sure there bolted back down right 😉
i will disagree with you there
i vented my frame and front bushing on 2 or 3 of the condors i had and it didnt get louder at all in fact i think it wa quieter
DO NOT VENT THE FRAME MAKES LOUD AS HELL
Only the front one, when you vent both, there going LEAD dirt in your spring / hammer /breech / trigger.
Better to put a O-ring around the second bushing, to keep you rifle clean.
I drilled my front bushing and that made a big difference. Make the holes as large as possible. I have not vented my frame as of yet. There were an equal number of no’s to yes’mat the time.
Here ya go Dollar! 😉

Ive done mine and would recomend it. Between the bushings ive used matting then a tube to keep it in place, makes it very quiet now.
probably not worth it then, if you have the short shroud,your not holding back the air like a full length shroud would.
There is a nice thread with pics on drilling the frame on here somewhere but i cant find it right now, but the holes are under the frame in the rail slot between the front bushing and the back bushing , far enough behind the front bushing to be hid under the forearm.
Talon Tunes shroud made for a 12 inch barrel. since i am using an 18″ barrel in the SS, I had to remove the internal Delrin baffel that came with the shroud.
What kind of shroud are you using? or are you just using the end cap?
so, leave the back bushing alone and maybe vent the frame-thanks guys. can’t decide about drilling holes in my rifle but if i do, where do you drill?
I can put my hand under the frame with the forearm off and feel quite a bit of air come out of the holes,and you can hear it too with the forearm off not so much with the forearm on , so the holes in the frame let quite a bit more air come back instead of going forward. That’s got to be better for keeping sound from going forward. This is at moderate power, like 14 grain pellets at 930’s , with 32 grain pellets at 1000 you hear the air come out from under the forearm. as well as all the other added noises from having the gun turned up.
For my 12″ .177 barrel I vented the front bushing but haven’t yet vented the bottom of the tube to the for-end area. When I did just the front bushing venting it was the first time I heard the annoying PING noise. I have to say the venting was a success in that the PING noise was no-longer covered up by the air expansion out of the barrel. My hearing is much better than average at low frequency but poor at medium and almost non existent at high frequency. So, any low frequency sound totally drowns out the medium and high ranges. So that explains why I hadn’t heard the PING before successfully venting the front bushing. The PING diminishes with lowering the FPS to a slightly slower and more accurate speed.
Venting the front bushing helps by creating more volume for air expansion.
Do not vent the rear.
I have heard mixed reviews about venting the frame, I chose not to vent mine.

LMAO !! On dam walk. ,
well it made my 24” .22 with 13” shroud quieter, but i have seen two people that had an SS that said noisier. i drill the holes the size of the small slot, so 1/8” i would say.
