Mike Bell Posted August 17, 2013 Share Posted August 17, 2013 Has anybody switched to the JP silent recoil spring system in their ARs? I'm wondering if the supplied spring is good to go, or do I need to also order the spring kit that's sold separately? I shot my bosses AR he built with one a few weeks ago (just 3 shots) and I could feel the difference over the regular buffer/spring set up. Its felt smoother and there was no springy twang in the butt stock. Link to comment Share on other sites More sharing options...
latech15 Posted August 17, 2013 Share Posted August 17, 2013 Oh, yeah. It is standard equipment for me. I haven't changed the springs. Link to comment Share on other sites More sharing options...

ctay Posted August 18, 2013 Share Posted August 18, 2013 Having never seen one of these - is it just removing the spring sound or is there something else? Seems pricey for just the twang sound... Link to comment Share on other sites More sharing options...
B45C22 Posted August 18, 2013 Share Posted August 18, 2013 It's just the sound/feel of the spring for me. I love the way it feels now. So smooth. Link to comment Share on other sites More sharing options...
anilson Posted August 19, 2013 Share Posted August 19, 2013 Got four more today, they now in all my rifles. Link to comment Share on other sites More sharing options...
denn1911 Posted August 20, 2013 Share Posted August 20, 2013 I have 4 of these installed, and they have been flawless. I just bought one for my LWRC REPR and will drop it in in the next day or two. Link to comment Share on other sites More sharing options...
hpnewby Posted August 20, 2013 Share Posted August 20, 2013 I love them. I'm running 18" with rifle gas in .223 and have an issue with the bolt locking back. I'm half attributing this to the fact that I need a slightly lighter spring in the SCS, but who knows. It makes a gun feel and shoot so smoothly. I'll never install anything else.

rangerguy Posted August 20, 2013 Share Posted August 20, 2013 I had one, being brand new to the AR platform I really couldn't tell a difference except the sound. I have since sold it and put the stock spring and buffer back in. Link to comment Share on other sites More sharing options...
ogiebb Posted August 20, 2013 Share Posted August 20, 2013 bought one just to try out.. now all my rifles have them Link to comment Share on other sites More sharing options...
Brine0 Posted August 21, 2013 Share Posted August 21, 2013 (edited) IMHO it seems that the JP spring system is not helping but instead introducing new variables to troubleshoot in the future. I get it and now there is zero advantage but i have introduced a new point of possible failure. If you have a variable gas block and the LMOS you are good to go those two are all you would need. At the most just use a light buffer in the receiver extension. Edited August 21, 2013 by Brine0 Link to comment Share on other sites More sharing options...
rvb Posted August 21, 2013 Share Posted August 21, 2013 (edited) I like the twang of the spring. no twang = time to reload! -rvb Edited August 21, 2013 by rvb Link to comment Share on other sites More sharing options...
jaredr Posted August 24, 2013 Share Posted August 24, 2013 I like the twang of the spring. no twang = time to reload! -rvb this was my first thought. i haven't used the JP silent spring so have no experience with it, but the sound of the spring in the receiver extension (or lack of it) is a pretty clear sign you're out of gas. Not sure I want to give that up... Link to comment Share on other sites More sharing options...
JGC Posted August 27, 2013 Share Posted August 27, 2013 I have one of the JP Silent Captured Recoil Springs in my CTR-02. At the 2012 AR15.com/Rockcastle 3-Gun Pro-Am, I was talking to some guys about how much they liked theirs and was going to order one as soon as I got home from the match. I was lucky enough to pick one up off the prize table and have been using it for a year with no problems. Link to comment Share on other sites More sharing options...
mpk1996 Posted December 10, 2013 Share Posted December 10, 2013 I have one and changed the spring due to the comb i am running. changing the spring is a little bit of an effort, but not too bad. the little 3mm allen screw is red locktited in and has to be heated to be removed. so, you push the spring down, lock it in the vice and "heat it till it smokes" (direct quote from the guys at JP) then remove the allen bolt. let it cool then carefully release the vice, remove the spring. install the new spring. compress it in the vice, intall the allen with locktite. good to go. its a great piece of gear. one other tip from the guys at JP. DO NOT run the normal buffer catch as it will make removal of the SCS very difficult. plus its better to have positive pressure at all times on the BCG from the SCS. if the spacing is off, use quarters inserted before you put the SCS system in the buffer tube. again there should not be any space between the SCS and the BCG with the bolt in battery. if there is, you might not always get good bolt lock up Link to comment Share on other sites More sharing options...
MetropolisLake Posted December 10, 2013 Share Posted December 10, 2013 (edited) I have a rifle that looks like a JP and a military'ish recce rifle had a love child, it's a BCM upper with a full mass BCG. I started out with a normal spring from Daniel Defense and a cheap carbine spring. The bolt speed was way too fast, very harsh. It greatly improved with a JP polished CS spring and Spikes T2 buffer, I thought it was the cats ass. However I just recently put in the captured spring and holy cow it's smooth. Now the only feedback is the shockwave from the muzzle blast, I don't have any mechanical feedback. It feels great and feels faster yet smoother for some reason. You don't really have a buffer smacking the back of the tube anymore and that is definitely noticeable. And this is without an adjustable gas block. Only thing I'm skeptical about is that I've had this gun for 3 years and I put the thing in and get my first double feed after just a couple of mags worth of shooting. Of course that was also the first time I loaded my Pmags to capacity too. Not sure if it's related to the JP spring. Hopefully that doesn't happen again anytime soon.

Albertl35 Posted December 11, 2013 Share Posted December 11, 2013 I do not miss the "twang" sound. With the JP, it feels more like a precision instrument. Link to comment Share on other sites More sharing options...
