Want to fine tune your AR and lose that annoying SPROING sound every time it cycles? CapArms’ new Quiet Shuttle System accomplishes that with impressive engineering at a remarkably affordable price. We got a sneak peak at one of these at SHOT and have a couple on the way for review. Stay tuned. In the mean time, here’s their press release . . .

SIBLEY, IOWA – CapArms is excited to announced the release of their Quiet Shuttle System. The all-new, CapArms Quiet Shuttle System replaces the traditional buffer spring in the AR platform and is designed to be quiet and tunable. Its patent-pending, drop-in ready design allows for less erratic recoil from the buffer spring and is significantly quieter than a traditional buffer system. The Quiet Shuttle System is great for suppressed ARs and allows for the additional tuning of the gas/recoil system.

The Quiet Shuttle System comes fully equipped with two (2) springs and two (2) shuttle weights that can be configured to cover the gamut of different pressures seen in the AR platform – right out of the box, whether a 5.56 carbine or a 300blk suppressed, short barrel rifle. This system is initially offered for carbine-length buffer tubes, but CapArms will soon be releasing an add-on, affordable spacer to use this in rifle length buffer tubes.

Come visit CapArms at Booth 2660 (shared with HIPERFIRE) at the Annual NRA Meeting and check out the new Quiet Shuttle System.

    • If you have ever owned something like a JP silent spring you’d know your comment is full of shit and ignorance. No amount of grease is going to eliminate that cheese grater sound using the original designed parts of a floating buffer and giant spring.

      • whoa, we go round and round on this every ~ few months or so, but it’s good to revisit. The grease may ‘quiet’ the spring, it may even dampen it a little, but a (product like a) JP Silent Spring [I ain’t gettin’ paid to say so] is worth the relatively stout price point, and just racking the charging handle one time will prove it.

        I think it’s the spring’s “period” that is ‘handled’. There’s a lot of things going on with the buffer spring and the physics overlap makes the interactions very complex. AT THE VERY LEAST, the buffer has to thread itself back thru the buffer spring as it is pushed by the back of the BCG. The orig. buffers have this little plastic chamfered plug to help do that and it’s a very basic (foolproof, not NASA) system. The original system ‘works’, fist-full-o’ love grease = better, Geissele = : ) , [I’m certain they peeps at CapArms have something here with their product or they wouldn’t bother], but the JP is currently where my money’s at. I wish I could buy you one to try it, you would thank me.

  1. …or you can get the Geissele Super 42 braided spring and buffer weight kit. It’s only $65, eliminates carrier bounce and comes from a guy who has advanced engineering knowledge.

  2. Sprinco anyone?

    I kinda like the spring noise it’s like the ar talking to you saying “hey buddy I just cycled correctly shoot me again”

    • At the very least, the lack of residual spring noise after a shot lets you know that your magazine is empty.

  3. That looks very interesting. Looking forward to the review. I need to tune the buffer/spring in one of the ARs and this may be a better alternative.

  4. Booiinngggg. Hehe hehe. Booiinngggg hehe hehe hehe.

    I hear Beavis every time I pull the trigger, and that’s the way I like it.
