I recently saw @Righter13's AR. When he pulled it out, I wasn't expecting much. You've seen one AR you've seen them all right? Well he had some pretty cool parts. One was the JP silent capture spring (SCS) that replaces the buffer and spring.

Anyone else use one?

I have considered using it on my 300 blk build. Not sure tough if it is really that big of a difference. I guess I really would like to hear it side by side.

It's not nearly as pointless as some of the other stuff a lot of us spend money on. What'a a few extra bucks for something that makes a gun operate noticeably smoother?

I will say that I don't see it being as effective in something like a 5.56 or 300 SBR, but I do intend to find out.

Since Ya'll are all on here talking shit about me and my spring I'll chime in.(sarcastic voice)

Agreed it is definitely not a need thing. It's a want thing. I had my wife buy me one for my birthday a few years ago because I couldn't justify the price.

After I put it and ran the charging handle I was in love. It is silky smooth and no metalic noise when charging it. Also the recoil impulse changes in my opinion.

Long story short if I could afford them for every rifle I would. When I find them on sale I pick them up.

Lol. You're too much.

Sent from my SAMSUNG-SM-N910A

I wasn't kidding, I really had to look it up.

9mm RRA buffer. Says 5.6 Oz
Wolff extra power carbine recoil spring
Wolff extra power hammer spring (red)
2.50 in quarters in the buffer tube.

You don't realize how loud the spring is rubbing against the inside of the buffer tube until you use on of these. That sound is like fingernails on a chalkboard to me now.

Completely agree.

I've always been under the impression that they are for the type of man that applies lotion to his penis, and then doesn't masturbate...simply to soften and moisturize.

I've stayed away from these due to the price and the horror stories. It seemed like every other week on other forums some newb was having cycling issues which were quickly remedied by removing this $125 part and replacing it with the standard $3 spring and $15 buffer.

If you don't like the sprooooong sound, then sell your AR and buy something else.

Ok, maybe that was a little extreme. JP makes good shit - no doubt. The problem is that there are other folks out there assembling AR uppers that are right at the very edge of the tolerances (gas block not perfectly aligned, bolt dragging a bit, etc.). You throw a high-end, very specific part like this on one of those builds and you'll get issues.

Embrace the sprooooong!
