How to get the "slap" out of an AR15?

[Buzznrose]

Okay how about the slap feeling when it recoils backward? I’m not talking the gun recoiling I’m talking the spring slamming into the buttstock

Almost every semi auto firearm has that feel in some shape or form. It is the action cycling.

I have a Ruger MPR, all stock. Never heard a slap, bong,spring or plunk, can't help you.

 

[LoonWulf]

It’s not hitting my cheek. It’s like the sound of the spring hitting inside the tube. Almost like a ping noise that’s super loud and I can feel it inside the stock.

I despise that "Proing". the cheap fix, if your not using them in cold weather is just enough heavy grease to deaden the sound. otherwise yeah captured recoil spring.

The recoil impulse can be smoothed out by heavier buffers, and adjustable gas blocks. I use adjustable gas blocks all the time now.

Evidently my hearing protection is working because I've never noticed anything like that.

That's the thing, without hearing protection* or with only ear plugs, I don't hear the sproing either. But with hard shell ear muffs that rest on the stock while firing, I hear the sproing.

*In my mis-spent youth.

BTW, the reason I put a flat wire recoil spring in my Armalite AR is just to annoy my shootin' friend with a pair of Colts. His sproing, mine almost doesn't. So, when he fires my lowly Armalite, well . . .

The sound won’t make you miss anything, I don’t hear them anymore but hard to imagine mine don’t make the noise they used to, likely I just can’t hear it any longer.

That said, I can’t even hear it with the volume turned up on a recording of my suppressed 458 AR, shooting subs.



In any case, if you are doing your job and the rifle is doing it’s job, odd noises won’t cause misses.

I do know there are products designed to solve the problem as well as home brew fixes, a google search will come up with lots of them.

The "sproing" of the spring inside the buffer tube is obnoxious to me too. Ear muffs that made contact with the stock during firing just amplify it. I changed from to a Magpul MOE stock to an ACS-L stock and lightly oiled the spring. It helped a little but its still there on a S&W M&P. Sorry I don't have a solution for you, but I understand where you are coming from.

Ditto.

Same reason I can't stand shooting AR's. I found the Chinese SKS's more pleasant to shoot to be honest.

I feel this too. Same with my springer air rifle. Took some getting used to with the air rifle, but it's another annoyance with the AR to me.

Gas spring Nitro Piston air rifles get rid of that annoying noise, too.

I like the AR for coyote calling and to be honest don't hear much of anything when I am shooting at coyotes. I am focused on hitting, the gun goes off, and I was either successful or not. I get that when sighting in an AR the spring noise can be annoying, but I don't notice it much any more. Fore me the benefits of the AR system outweigh the detractions much to the dissatisfaction of the coyotes. YMMV

Out of all the AR’s I’ve owned, only one has made the “sproing” sound. That rifle was an old Eagle Arms A2, and the “sproing” was very noticeable. Very weird for an A2 buffer system. Tried grease and it helped some, but I finally just got used to it. A few years later, I rebuilt it into an 18” 6.8 SPC with carbine stock/buffer system, and never heard the “sproing” again.

Gas spring Nitro Piston air rifles get rid of that annoying noise, too.

Yea, I owned one. It was nice. LOL Wish it had been as accurate as my RWS springer though.

 

[TonyAngel]

Flat springs are a PITA to get past the plunger. Stick with a mill spec spring.

Grease has no business on any part of any AR, or any firearm you’re gonna need to trust. You know what you get when you mix grease with oil and the debris associated with a firearm being fired? You get mud. And sort of an abrasive, like lapping compound. Traditional lube, oil if you will, has two purposes. It, of course, lubricates and it provides a medium by which the working action of the parts displaces crud. Grease keeps crud where it is.

if you don’t like that boing, maybe check the diameter of your buffer tube and see if it’s a mil spec or commercial spec diameter. If it’s commercial, get a mil spec. Tighter tolerances. I also run a buffer filled with tungsten powder. Regular buffers have what are essentially washers in them.

a "tune" will usually remove a great deal of the vibration from decent quality springers. Ive shot some of the big RWS 350s that were tuned and while they lost some fps, they also shot with much less jolt, and none of the PRONK! that they originally had.....The 48/52s are incredible when tuned.

Any recoil “flinch” is a function of anticipating the aftermath of the trigger pull; I find that if I am concentrating on technique and the sight picture, I hear the gun discharge and I feel the recoil but it is always secondary to my concentration on hitting the target. In a hunting scenario, I notice just about nothing at the discharge, I am concentrating on the animal. You will need to shift your attention to “shooting” well and away from the recoil noise - shooting well is training your mind to shoot well.

 

[bassjam]

Every AR I've shot with a carbine gas system has that annoying "sproing" sound. I hate it, makes the gun sound like a cheap toy to me. I greased the buffer spring of my M&P Sport which significantly cut down on noise. I also have two builds that are both mid-length gas systems which seems to help to begin with (not sure why). In one I put this silicon covered spring which seems to eliminate the slapping sound. http://damageindustriesllc.com/store/index.php?route=product/product&product_id=409

In the other I put a very thin amount of 0000 Go Juice on the spring, which seems to help in that case as well. I should also mention both of my builds have adjustable gas blocks.

OP if you're looking at the MPR, it's got a rifle length gas system which should help. If you still notice the spring noise, I suggest trying the damage industries spring I linked, or Larue also makes one. The other option is the JP system some have linked.

 

[edwardware]

For the spring "sshhproing" noise that is mostly bone-conduction through your cheek weld, I observe:
1) You get used to it, and eventually its absence becomes a hint that the bolt's locked back.
2) You can hone the inside of the buffer tube smooth to reduce it, somewhat.

My head doesn't seem built right to use muffs with a rifle and I don't even attempt to anymore. Good plugs for me.

 

[DeepSouth]

I’m one the people that hear and fell the sproing in every AR I’ve ever shot except a friends Daniel Defense. It is rather annoying but I’m not a big AR fan to begin with so it’s just not a big deal to me as their are other things about them that annoy me more.

But I’d just like to point out that by the time you heard and/or feel the slap/sproing the bullet is out of the barrel and well on its way to the target, Therefore their is no way it can affect accuracy. Now mistakes made because of the anticipation can certainly affect accuracy, but that should be a fixable problem, as it’s behavioral....for lack of a better word.

 

[Sistema1927]

The only time that the "sproing" caught my attention was the first time i fired an M16A1 in basic training. I thought "that was different", but then quickly forgot all about it.

 

[Bfh_auto]

It’s pretty much like a pogo stick sound. It always makes me move my head or close my eyes.

It takes time to overcome it.
I ran at least a thousand rounds through mine before it became a normal sound.
It's definitely irritating.

 

[Robbins290]

Sounds like the buffer weight is light and/or over gassed. I have about 15 ar15's. And none of them describe the issues you have. The spring is noise when new. But will go away or you till get immune to it. I would go to a range where you can rent some and try another. could be a issue for that rifle.

That's been my exact experience also. It's to the point that I would probably start checking for a malfunction if I did NOT hear the "sproing"

Captive recoil spring. Problem solved. Not cheap though.

[Varminterror]

H2 buffer, adjustable gas block, little grease in the tube. On a rifle length, JP Silent Capture is the way to go. Just too much length in there to really eliminate that spring lash.
