Looking to start shopping for another build in the works, and I've always seen these as more expensive than they're worth - but is there some advantage to these captive buffer weight/spring things that makes them worth the 800% markup over a normal spring and weight?

Personally for me, I say for everyday use it's overkill versus a standard buffer. Now if running suppressed and trying to take out all the noises and rattles... worth it !

Yep, this is the reason I run several in my suppressed rifles. For everyday rifles it’s unnecessary.

Not familiar with this product, but a Tubb’s flat wire spring and a tungsten buffer work great in my rifle and don’t really hear anything going on in the buffer tube when I shoot it. Wasn’t all that expensive either. If you’re looking to quiet down all the rattle and “sproing,” this is a way to get there.

I put the JP Silent Capture spring in all of my builds.

Honestly, some light lube on a quality buffer spring does a lot to eliminate the 'sproing'.

I used either Colt H2s & SpringCo Blue or VLTOR A5s & SpringCo Green Rifle springs (in A5 RE, of course). Also the Geissele triple wire spring and buffer works great at quieting it down.

I just put a Geissele buffer and spring in my rifle today. I put a light touch of grease on the coils and the buffer before installing. Buttery smooth, and no noise or scratching.

use the JP Silent Capture in my patrol rifle as well. Maybe overkill but I like it and others who have shot my rifle seem to as well.

easy way to get rid of the sproing is to grease the spring,

just a dab of axle grease and it is as quiet as can be

Yup, I ran a thin coat of white lithium grease down both sides of my flat wire spring to eliminate the scratching noise. It's about as silent as I would want.

I have one in my 3 gun and PRS gas gun rifles, both of which are also equipped with JP low mass carriers and adjustable gas blocks.


I do really like the way they change the recoil impulse. It is easier to feel than it is to describe. Best I can say is that it eliminates the sensation of being able to feel the rifle cycle when you shoot it. Shooting several of my rifles side by side I can feel the back and forth movement of the bolt carrier and buffer in my suppressed 16" rifle with H2 buffer and standard m16 carrier. In my low-mass and SCS equipped rifles, I can't feel the action cycling. I feel recoil, but it feels like I am shooting an AR with a completely closed gas system. Or like a bolt action, I suppose.

As far as any noise goes, as others mentioned a bit of grease on your buffer spring takes care of that.


Worth it? If you are seeking that last bit of refinement in tuning the recoil out of a competition rifle, perhaps.


I'm not going to get rid of mine, I like them in the rifles I use them in, but I'm not going to buy one for every rifle.

A common sentiment I get when I talk about tuning the recoil out of an AR-15 chambered in 223 is a joking assertion. "What a wimp, 223 doesn't even recoil."


I get it, an AR-15 is a soft shooting rifle. Especially compared to say, a bolt action 300 Win Mag.

But a lot of people don't appreciate how much of that recoil, and how the duration of that recoil impulse, has to do with the oscillation of the bolt carrier group and buffer.


A frequent reaction I get when someone who is reasonably familiar with ARs, shoots one of my tuned match rifles is: "Wow, how do you get it to feel like that?"



Necessity? Nope. But it is a nice refinement, as part of an overall system.


If you drop one into a standard AR without an adjustable gas block, you will probably be disappointed. That one part, in and of itself, won't change a whole lot.

I find this a "non issue." I just grease up a regular spring and it is good to go.
