New Owner, Quiet that action!

Hey "hyrule" go for it buffers are used in other rifles and quiet them a "little" but hey all little things add up... let us know how it goes... good luck.
 
Ya as a 07/SOT2 I will agree if your wanting quiet go bolt. As far as the noise the 15-22 makes its very noticeable. Me and Chattanoogaphil did a side by side test of a 15-22 and a sig 522 and the bolt noise is much greater on a 15-22. I think some of this is due to the "buffer tube" on the 15-22 its like a amplifier for bolt noise. But a integral bolt gun shoots any ammo subsonic so no need for subsonic ammo and has no receiver fart or mechanical noise other than hammer drop, trigger reset, and bullet strike which are the dominant sounds of the shot
 
Might try drilling a small hole in the rear of the " buffer tube" if there isnt one there and add alittle spray in foam as a dampener
 
A little knowledge can be a dangerous thing.

One has to begin to wonder the "Why?" aspect of all this endevour... If the "quiet" is for you, get more effective hearing protection. If it is for where it's being used/going to be used and why, then it begins to sound a bit sinister. But maybe that's just me. Buy a paint ball rifle. :confused:
 
Man your brave, shooting at that small target inside. I haven't gotten enough hang of my slidefire to hit that small area reliably yet. I also dont have a 3 lb trigger though either. I actually have an old bolt rifle that was my dad's first when he was 12 that works beautifully. I thought about having it threaded sometime in the future but semi auto is too much fun. I hear the 10/22s are quieter hosts. I thought about getting a 10/22 and going bullpup with it and making that my primary suppressed weapon when not using it on the handgun. But who knows when that will happen, i want to get the suppressor first.

This is my private little range. Don't assume it's just a cardboard box. A little background on my range.

The room is 30ft long, 10 ft wide and 10 ft high. The larger 2 x 4" box (1 ft deep) is a back stop. It's filled and has a 1/4" steel plate behind. That box is roughly the size of a man sized sillhoutee. The carboard box is filled and is the primary target. Once it's used, it can be discarded and you start with a fresh target. Furthermore, as I tell people, of you can't hit the small box with a rifle at 25ft, you have no business shooting. Find another hobby! The back stop has no problem w/ .38 as well. I have ventilation and the room gets cleaned and I mop at least once a week.

I won't get in a debate on lead exposure but will tell you heavy metals exposure is something I used to test for in a lab. Public indoor ranges are a far larger concern than the few rounds I shoot here and there.

I've designed and made a bunch of elaborate back stops in the past and kept coming back to the simple methods. They work the best. If interested, PM me and I will share what I have done and tried.
 
Thanks everyone for the replies! It's not that I need dead quiet its just I like as quiet as possible with a gun that I love and shoots reliably every time! I want to shoot behind my parents where it's legal and there are no noise ordinances but a particular neighbor has complained about the noise from shooting the 22s. In the interest of keeping the peace I have looked at the suppressor as an option and a great excuse to get something that is awesome anyway! As to the hole in the buffer tube, I'd like to keep away from anything permanent. Besides the end of the buffer tube has a plug that could be pulled out and then filled if you wanted with that foam.

I can definitely hit your target with a rifle at 25 yards but with the slidefire since I don't have a special trigger its harder to get the touch just right to make it work and keep excellent aim. I am interested I can threading my dad's old bolt sometime but figure I'd wait until I actually get the suppressor.

After reading the whole thread I think I can understand your motivation for modifying your gun(s). Since the primary source of mechanical sound seems to be the return of the bolt to battery it might be necessary to consider "blimping" the receiver section of your rifle. I don't know of any easy way to do this chore other than building a foam mold core around the gun then creating a hard-shell over that, taking care to allow for empty shells to be removed and controls to be used. The sound you are trying to eliminate is a fairly high-frequency, short duration, metal-on-metal type that would respond well to foam dampening within a rigid shell. The noise emanating from the ejector port of the rifle could be diverted down following the path of the spent cartridges. Actually, a spent-shell diverter could be used to muffle the sound of the returning bolt by directing it down, possibly into a catch-bag for empties. There would still be sound emission from the body of the lower section but such a diverter would possibly clean up the most objectionable of the "crack" of the action. Just a thought...Good Luck.

Geez, why go through all that? Just buy a bolt, pump or lever action. This is sounding like a project to make a sow's ear out of a silk purse. :)
 
Buy the neighbor an I-POD, ear plugs or invite them over to shoot! ;)

Hey, the OP seemed to want an engineering project so I tossed him one! His ambitions may not make sense to everyone but without his kind of thinking we would still be using slow-matches to ignite our charge (those wheel-locks are so overrated!).
 
Might try drilling a small hole in the rear of the " buffer tube" if there isnt one there and add alittle spray in foam as a dampener

My tube had a cap in the end that fell out one day at the range. I felt it hit my foot and it took me about half hour to figure out where it came from. As an insulator, I'd suggest against spray foam in there. It has great expansion capabilities, and while I'd bet the tube would handle it, if you didn't have the cap just drilled a hole it could rupture something. I've seen spray foam do some amazing things. I'd suggest just stick some fabric or cut a cylinder of styrofoam and put in there

Uh, am I missing something? The "buffer tube" on a 15-22 is hollow tube, one-piece with the lower, and closed where it "joins" the lower and open all the way to the other end. What need is there to drill a hole?

Neither of my 15-22's have anything closing off the aft end of the tube. :confused:

Ya mine had a little plastic cap with a grab-tab. Convenient because I wrapped a couple batteries and those springs you always lose in a sock and stuffed it in there. A dab of Elmer's glue on the cap and nothing has fallen out yet.
 
I've got a few survival items in the buffer tube on mine. Waterproof matches, a small fishing kit, spare batteries, some tylenol and antacids. I keep spare allen wrenches in my grip storage for adjusting my red dot and another set of 2032 batteries for it. I drilled two small holes on opposite sides of the buffer tube cap and epoxied a zip tie through it for a pull tab. It's worked great for a year now.

Strange ...

We have several 15-22 owners at our range and all of them have the same open-ended tube. There has been some discussion among us about using it for storage, but no one has come up with a way to close the tube except a rubber plug.
