I recently got a 308 suppressor, and have been using it on both my 308 bolt and 5.56 AR-15. My 308 bolt is great, but the AR-15 action clatter kind of pisses me off. I asked a coworker about it, he recommended greasing up the buffer spring to reduce the "sproing" part. Any other hints on how to reduce the noise? Heavier buffer?

Re: AR-15 Action Clatter
Do not grease / oil the spring in the buffer tube. It is not related to suppression of noise related to a projectile leaving the bore.
If you want a *more* quiet AR - get an adjustable gasblock / gastube and shut the gas off. Now the AR is a single shot. This will be the single biggest thing you can do.
Good luck

Re: AR-15 Action Clatter
The can is over gassing the action. All cans are not made the same and some cans made for bolts will create large enough back pressure to create havoc. IF the designer has speced the unit for a bolt gun he can increase the diverter/primary pressures considerably. In your case? Most likely that extra noise is bolt/buffer slam. Stop. Mo's solution is correct though, get the right amount of gas down the tube and the host can remain fully functional. But you don't have to completely block the gas, reduce it through the use of an adjustable block.

Re: AR-15 Action Clatter
Do you hear more than the normal AR-15 "sproing"? Most experienced AR-15 shooters don't notice any sproing anymore just due to getting used to it.

This is why i will run a piston upper when suppressing 5.56

Re: AR-15 Action Clatter
Okay, adj gas block is on the list. I hardly shot AR-15s until I bought one the Monday in December right after a certain event, convinced they would be banned. So I'm not used to anything but bolts. I'll get it down eventually...

Re: AR-15 Action Clatter
You will always have the racket of the bolt slamming home. It's a fact of life with AR's. Noisy to you but not all that noticeable down range.

Re: AR-15 Action Clatter
Well, I shot with some other people. 5 ft away, didn't really notice. I think I'm just overreacting to it. Another guy's AR-10 was quieter with my 762-SDN-6. Now I need me one of those.

Re: AR-15 Action Clatter
The noise can be much worse if you are using over the ears hearing protection. If they contact the stock, which almost can't be avoided on an AR, it will channel the mechanical noises directly to you ear instead of blocking it.

Re: AR-15 Action Clatter
Good explanation. I was using them; they were on the stock.

Re: AR-15 Action Clatter
I just finished my MA-TEN build utilizing the MagPul CTR Stock, VLTOR Carbine Receiver Extension Buffer Tube, and the JP AR-10 Silent Captured Spring. The Silent Captured Spring is truly amazing in eliminating the cheese grater sound as well as making the cycling action extremely smooth... It's almost like shooting a bolt action! It is a bit pricey, but, for me, is was worth it. YMMV.

Great, now I have to add THAT to my shopping list. Looks cool!

Re: AR-15 Action Clatter
JP's silent capture spring is probably the best choice for reducing the spring noise.

I would NEVER suggest blocking the gas to eliminate cycling completely. It will work, but it will greatly increase the chance of damage to your weapon. Especially if you're running a can that's increasing the back pressure anyway.
Will it work, yes. Is your rifle designed to handle that kind of stress. No.

No picking a fight and I am just curious.
What do the people in England do when they convert their AR15's to single shot to avoid damage from blow back pressure?
