Subsonic ready, or modification required?

[BELT_FED]

all you need is the springs to run most all sub rounds if you get feed problems and dont wanna run a real can you can run a booster, but ive not found any ammo that wont feed since ive upgraded springs with or with out my suppressors

What springs?

What's a "booster"?

 

[BELT_FED]

j&p yellow spings will reduce the amount of energy it takes to reset the hammer.. so it can be cycled by weaker ammo...

a booster is best described as a muzzel tamer with very small porting... so that it creates alot of back pressure.. the same way a can does.. this will in no way silence the weapon it will make it louder

Already got those.

I actually had an idea along that line. I was thinking an actual barrel extension that

0) Had the same OD as the barrel itself so that it would provide an uncluttered appearance,

1) That could be threaded on (a threaded barrel would be needed of course).

2) The business end could be machined to accept a 1/4-inch hex wrench for the purpose of tightening the extension. This would preclude having to have some sort of wrenching surface on the outside of the extension.

3) The end of the extension itself could be threaded to accept suppressors/flash hiders.

4) The extension itself could be made available in 2-inch, 4-inch, and 6-inch versions to allow for more or less back-pressure as the shooter night require.


When can you have some ready? I offer my services as a beta tester.

 

[giguchan]

i just have one question... why would you want to use weaker ammo? maybe i've missed something.. what do you gain? or loose?

 

[Lian]

ammo that runs below the speed of sound... dont have the sonic crack/boom.
hence, subsonic ammo.

and apparently certain brands of SS ammo doesnt cycle the 15-22 properly, hence the springs.
or, getting a suppressor to create more back-pressure.

What he said. A suppressor can be expensive (pay for the tax stamp at $200+, and THEN pay for the suppressor itself at $300+). To avoid the need for a suppressor, you use subsonic ammo because it's quieter when you shoot it.

Adding a fake suppressor or a barrel extension would give the round more velocity without resulting a louder report you'd get with standard velocity ammo. This gives you the best of both worlds - range and more silence.

This is only really necessary for hunting.

Subsonic rounds will not cycle the bolt properly, at least for me.

I'm going to test that theory on Sunday (weather permitting). My 15-22 has lighter hammer/trigger springs, and this is supposed to help with the subsonic issue.

are you using a suppressor, or spring set?

 

[BELT_FED]

yes.....

 

[ChattanoogaPhil]

+1 Yes....

CCI Standard Velocity and Augila match consistently shoots subsonic, and never had any trouble with either cycling absent a suppressor.

 

[giguchan]

Thanks for the replies... I was wondering. the noise to me is not that big of a deal.. perhaps maybe at an indoor range

 

[Rattles]

I have used the Aguila SS too and they cycled no problems. I only threw about 5 or 10 in the magazine at a time and the rest my normal ammo. The SS' have more of a "thump" to them and the other ammo "snaps".

For reference my gun likes Winchester bulk and CCI Minimags.

rattles,
thanks for the reply. I dont know if the winchester you refer to is the "wildcat" stuff. Thats in the book as not being reccomended. I guess if it works then it's good to go.Thje Aguila stuff gets a thumb's up. it's wild that you can have 2 of the same gun one will perform diffrently than the other. I also called smith too.. the guy on the phone was like"it's a .22 how much would you really save by buying cheap sub-par ammo anyhow? it's why you bought a .22 in the first place".

Makes sense to me.

I think a lot of it depends on the break-in. Its the 333 and 55 bulk Winchester BTW.

 

[giguchan]

Hey thanks for the reply.
I will keep that inmind!

No, stock parts.
