  • AR-15 with carbine-length buffer tube


There are a lot of upgrades available for the shooter who wants to improve his AR-15. Many of these upgrades are designed to reduce felt recoil or improve issues caused by poor fitment or sloppy design in standard Mil-Spec components. If you’re looking to improve upon the standard buffer assembly in your weapon, look no further than the Armaspec Stealth Recoil Spring Buffer Assembly.

Advanced Design, Reduced Friction, and Recoil

The Armaspec Stealth Recoil Spring Buffer is an advanced revision of the standard buffer system. Instead of a single large buffer spring and buffer weight crashing around loose in the receiver extension, the Stealth Assembly features a two-stage recoil spring assembly that eliminates the excessive violent movement of traditional buffer systems as well as the friction of uncontrolled parts inside the buffer tube.

The Stealth Assembly is kept under continuous tension against the BCG. An o-ring is incorporated into the head of the buffer to eliminate metal to metal contact. The dual springs of the Stealth Assembly are held in place by a central rod, operating in two stages to absorb excessive recoil force. Since they never touch the inside of the tube, the springs won’t make extra noise or wear prematurely like those in traditional buffer systems.

Drop-in Ease, Reliable Performance

The Armaspec Stealth Spring Assembly is designed to easily replace the standard buffer assembly in your AR-15 with no extra modifications or special receiver extensions. Its dual-stage operation allows it to operate smoothly, with less recoil and fewer failures than other buffer systems. When you replace a Mil-spec buffer and spring combination with the Armaspec Stealth Buffer Assembly, your accuracy and follow-up speed will improve and you’ll spend more time at the range than on the bench.

    I've had the ARMASPEC Stealth recoil spring assembly for over a year and about 3000 rounds with it and I have to say this thing is still churning along beautifully. I went with the heavy for my 14.5" 5.56 and there is zero recoil, zero spring "ting", zero failures. It's pretty stiff when using the charging handle, but to me that's a good thing. It's telling me the spring isn't losing any stiffness. I would recommend this product highly.

  • Perfect fit

    Love the item. Easy to install. Quiet when shooting. Love the fact I don’t need a retaining pin for it.

  • Quality product

    You should try this I love it?

  • So Far, So Good

    I put a few hundred rounds through a rifle that had this recoil system installed. Seems to be very good quality, much like the JP Silent Capture System. So far, so good.

    These actually work well, was a bit skeptical at first. Heard friends raving about theirs so I got a couple. Very smooth and very quiet. Love it.

  • Armaspec captured spring

    These work great, 1/2 the price of the JP captured spring. We pretty much only shoot suppressed anymore so we really started to notice how loud the twang of a recoil spring can be. These stealths make a huge difference when shooting suppressed and they are reasonably priced. If they were say...$50 instead of $80 I'd put one in every AR we own. Although, definitely worth the $80 to throw these in the rifles that get heavy rotation. Get one, you wont be disappointed.

  • Seems like a great alternative to a standard buffer spring

    Installed this on a 7.5" pistol build with an adjustable gas block. I only have 100 rounds through it, but what a pleasure to shoot. I will probably replace the buffer spring in my others with this as well.

  • Same quality as the similar JP style Buffer assembly

    Posted by Erik Olsson on 16th Nov 2018

    Great quality and about 1/2 the price of the JP Enterprises captured buffer assembly. I ended up going with the H2 variant due to using a pistol length gas system and wanting to better control the very high psi due to timing and the fact that the Armalight gas system was designed around a rifle length gas system. The is a little heavier than a simple buffer assembly but the assed weight is not a problem because the entire firearm is very light even with optics. As is with BUIS and reflex optic (Meprolight M20) it is still under 7 lbs. If you are a 3 gun competitor r simply want a more progressive recoil impulse I highly recommend this part.
