ARMASPEC SRS™ Stealth Recoil Spring ™

[GOST]

2674

The Stealth Recoil Spring™ SRS ™ is a self-contained multi-stage drop-in replacement for your standard buffer and spring. The Stealth Recoil Spring ™ is designed to reduce felt recoil as well as keep the buffer spring from rubbing against the inner wall of the buffer tube. The buffer mass is designed to stay under constant tension against the bolt carrier and the O-ring on the head of the buffer mass prevents metal on metal contact.

The Stealth Recoil Spring comes in 5 variations. SRS-Carbine at about 3.3oz equivalent SRS-H at around 3.8oz equivalent SRS-H2 at around 4.7oz equivalent SRS-9 at around 5.3oz equivalent and SRS-H3 at around 5.6oz equivalent. The Stealth Recoil Spring will be available first quarter 2017.

MSRP $79.00

Hm, interesting. Kinda like the JP. Wonder how spring life is on these.

Does it require the castle nut, end plate and RE to be uninstalled to remove? If so, I'll pass. I'm taking my JP captured spring out next time I work on my AR for that reason alone.

[fledge]

My JP captured spring goes in and out like a milspec spring and buffer. No disassembly required.

[Duffy]

You're right, it just doesn't remove the same way , the retention pin needs to be pressed and held down, then tilt the receiver to let it slide out.

[fledge]

Yes that's true. The directions specify the retaining pin isn't necessary. I'm looking forward to reports on the Armaspec, as long as it is an innovation and not merely a copycat (that theme keeps coming up these days ;)).

[Aragorn]

Also curious to know if it'll work with a Law Tactical Adapter. The buffer face has me unsure.

[Duffy]

I like the JP captured buffer and spring, it changed the recoil characteristic, my AR feels like half a SCAR16. SCAR16 has a slow gentle push, my AR's recoil is usually a much sharper knock. It's also easier to keep the muzzle down with just an A2 with the JP captured spring and buffer installed. My tiny 5 ft tall wife has no problem hitting a steel target one after another consistently, using an RMR piggy back mounted on an ACOG no less, that's a pretty convincing result.

Roger, Is this the only reason you're removing the JP unit? Is there a performance issue you're experiencing that's motivating you to dump the captured spring? I need to know your reasoning; I intend to install one in my SBR in advance of getting my suppressor, but if there's a good reason not to (Other than this new option), I want to know as I don't tear down that area of my guns as a mater of routine.

[Duffy]

Joel,
As it turns out, it was my own misunderstanding of the unit to think I had to remove the RE to remove the JP buffer. Because it's a self contained unit, it doesn't want to jump out when the buffer retention plunger is pushed down. JP's instruction states the retention plunger isn't needed, but I don't think it mentions how to remove it WHEN and IF it remains lol.

I'm happy with it otherwise, but it's expensive, I might give the Armaspec kit a try.

Hmm. I had no interest until you posted that it changes recoil characteristics.

[Duffy]

The AR with LMT MRP upper is the test bed for pretty much all of the new products we develop or buy from other manufacturers. The difference between various comps and brakes, and the A2 it has now, is quite noticeable, till I installed the JP buffer and spring.

It doesn't feel as though I had a brake installed, but it stays on target better and recoils softer with the JP captured spring and buffer than with a conventional spring and H1 buffer. I couldn't care less about the "boingggg" spring noise, I got it as novelty item to play with. I like it a lot. The price is high, but that's to be expected from someone like JP that's done its homework.

[alamo5000]

I have a question for ya'll. My SBR uses an extra power spring AND a heavy buffer. How do these kinds of products (any brand) (this one or JP) work in that scenario? Do they make heavier ones or is it just what it is?

JP has different versions, plus springs, weights that you can use to customize. H2 version looks like it has a one of the steel weights replaced by a tungston weight.

The Armaspec version has 5 variants, though on their site it's out of stock and no options show.

Straight out of the box, I doubt that the Armaspec version will work with the Law Tactical folding stock any better than the JP captured spring. My JP versions have (and Armaspec version appears to have) a fixed guide rod that goes inside the bolt carrier as it compresses the spring/buffer during the firing cycle. Law Tactical uses a SOLID extension adapter that fits into the rear of the bolt carrier. However, it "appears" to my eye that the guide rod is thin enough that one could drill out the center of the Law Tactical extension adapter so the rod is able pass through it and into the rear of the bolt carrier. It would cost $29 to buy a spare LT extension adapter to try it. Hope this helps.

Yes, you can. A guy did that here:
