Lighter recoil spring?

I have no place to shoot most of the time other than my back yard. While legal in my area I have no desire to be any louder than can be helped ( I live in a nest of liberals but that is another story). At any rate the CCI quiet is very and works well in my AR 15 22. It even cycles and chambers the next round to my surprise. However it does not cock the hammer. Would it be possible to use a lighter recoil spring while using these low power rounds to allow the bolt to cock the hammer? Any other thoughts?

There could be other solutions. But if it is legal in your state buy a suppressor. That would probably be the best solution.

Yes it is legal but funds are short at this time. The suppressor guy around here wants about $400 plus the stamp $200:( Plus I am told that these 22s are not that much quieter with a suppressor than they are with the better subsonic loads. The sound of the bullet hitting the backstop is as loud as the gun with these CCI rounds.

There are some cheaper options out there for suppressors where the over all cost would come out to around $400-500. One of the companies I have considered is Huntertown Arms

I know subsonic ammo is not recommended for the 15-22, but have you tried other brands to see if they will cycle properly?

The problem is not so much the recoil spring on the bolt, it's the hammer spring. Reducing the hammer spring power is a good way to ensure a high percentage of failures to fire.

Thanks. Ya I would not lighten the hammer spring,:o I was hoping just a little less tension on the bolt might be enough to get the hammer to catch. How about a 50 grain subsonic...any such animal?

Why not buy a cheap single shot and look on You Tube for the "oil filter silencer" and not **** up such a nice rifle as the S&W 15 22???

Not screwing any thing up. A lighter recoil spring has been used on many guns to deal with loads of different power. I would like to shoot my gun in my backyard without disturbing the neighbors. Thought I might tap into the knowledge on here and see if anyone had done so on the 15 22 to allow cycling the subsonic rounds. Foolish me, thought that was kinda one of the purposes of these forums:rolleyes:

i run the jp yellow springs without any issues as well although ive read about similar issues for some.

springs are cheap so why not just give it a try, you've got nothing to lose but a few dollars. and they're not permanent so you can always go back, its not "screwing up" anything.
 
What Majorlk was saying ( I think) is that a softer recoil spring won't negate the pressures needed to cock the hammer. Lighter sub sonic round has a hard time pushing the bolt back over the hammer to reset it. If ammo is putting out less power the hammer spring has to be lighter, if the hammer spring is lighter you could run into light primer strikes.

Just save up for the suppressor and tell your neighbors to go hug a tree.

Exactly. There's no harm in trying, though, but don't be surprised if it doesn't work as you expect.

That's primarily with centerfire pistols with a locked breech. Blowbacks are another animal entirely. There is a very small allowance for the balance between recoil spring pressure and bolt inertia.

You asked and got answers based on our experience - which is exactly what you asked for. That the answers are not what you wanted to hear is immaterial. :)

I combined the yellow reduced power JP springs and the speed hammer modification. IMHO I think if you decrease spring force you should decrease the mass of the hammer too to compensate.

These modifications increased my reliability with subs and HV. The only ammo that has failed to fire in the last 1500 rounds are factory duds. I have had no FTFs because of light primer strikes.

Aguila makes a 60gr SSS I have not shot these in my Smith PC but they work in my Colt M4 and my Walther P22 . Aguila also makes some 20gr 500 fps , they are not recomended for rifles but I have killed racoons with these useing a bolt action Marlin .

What sub sonic rounds have you run? What is the speed hammer mod? Thanks

When the bolt is forced back it has to push on the hammer to reset. There is friction there which can be lessened by polishing. Without any added cost why don't you try and smooth out the surfaces that rub together reducing the friction which will make the bolt move easier. Personify I polish all mating surfaces and spray on Teflon chain lube which makes the surfaces slick and it doesn't attract dirt.
