Armaspec silent buffer review

[MarikinaMan]

Started playing around with a rifle I bought used about 2 years ago. Did some drills, and immediately noticed how flat shooting and cool sounding the rifle was. It was flat and was very easy to keep on target even at an almost full auto rate of fire. I was stoked.

When I was cleaning it, I then remembered that it had an Armaspec silent buffer system. Watching some videos of the drills, I noticed that the ejection pattern is like 1 o'clock. That piqued my curiosty.

I researched Armaspec a bit more and found out that I can change the buffer weights. I ordered an H1 and am waiting for it.

Ive seen this system for as low as 44 bucks. I think its very reasonable. If you were to buy a Springco chrome silicon spring and a Spikes T2 buffer, I think the cost would be a wash making it a decent alternative.

After I install the buffer weight (16 bucks) I can come back on here if it does change the ejection pattern and do a full review, if anyone is interested.

please do a review

Why change the ejection pattern if the rifle runs reliably?

1 o'clock pattern is good if you're firing next to another shooter. No hot brass down the shirt, (or in the face) of a guy that's armed is a good thing.

Forward ejection pattern can be a sign that the rifle is over gassed. There is the potential that the rifle can be worn down in that situation. I don’t necessarily believe this. There is also the potential that a fine tuned ejection pattern will allow the gun to run even flatter, something I am willing to explore for 16 bucks.

ARs are normally over gassed for reliability with various ammo. I reload 98% of my ammo so I am in a situation where tuning makes a bit of sense.

I have another rifle that I tuned with a Spikes T2 4.0 oz buffer and a Sprinco heavy spring and I really like it. It ejects are 3 o’clock and it just lobs the cases in a neat pile 4 feet to my side instead of throwing them 20 feet forward. It’s been very reliable too.

At the end of the day, these little tests help me understand my rifles better and is part and parcel of my enjoyment of the sport.

Can the Spikes`s set up do that with Normal ammo as well?

Well, tuning for specific ammo can produce a different result with another brand/batch/load of ammo.

The Spike's buffer comes in different weights, and springs can be purchase at different strengths. You can definitely achieve the same tuning with the Spikes, or even regular buffer selections. The Spikes is interesting in that its all tungsten, there are no moving parts inside. Less noise and felt recoil. H1 buffers can give a little rattle when you shakem.

I agree that having a properly gassed AR clone is optimal and tuning an AR clone is a good thing, but there are a lot of variables that affect the ejection pattern.
Action spring
Buffer weight
Gas port size
Gas system length
Ejector length/spring
Ammunition type. (Spec M193 as a starting point)

I shoot a lot of steel cased (weak) Wolf and brass PMC A-load and can run M193 equivalent in my DI gassed AR's and change ammo types with gas metering with an adjustable gas block and using standard weight action springs w/3oz carbine buffers. Total reliability with either type ammo with a couple of turns of a screw.

*simply turning the gas up or down will change bolt speed. The faster the bolt goes the more 1'oclock the ejection pattern is. The less gas the slower the bolt speed.

Ejection pattern can be 1 symptom of an over gassed DI AR, but there are usually other symptoms that accompany this. Case ejector swipes, blown primers and or more noticeable recoil.

My point is that a quick change of a buffer and action spring will band aid the symptoms, but is not as effective as gas metering when you tune the AR clone du jour.

Do carry on with your testing. Reviews are good for learning.

The weight arrived. It took 3 minutes to unscrew one bolt. clean up the assembly a little, oil some of the sliding surfaces, slip on the weight an put it back together. Test firing this weekend.

Thanks for sharing.

I've really been eyeing these springs because, while the AR is by far my favorite rifle, I just can't stand any rattling / loose stocks, nor the cheese grater sound.

It just makes the rifle sound cheap, crappy, ill-maintained, everything bad. Call me whatever you want, it sounds like junk.


I have ONE JPE version, but ArmaSpec's version is like what; 1/2 or 1/3 the cost?? Very tempting........


That said;

- Does anyone here have one of the JP springs to compare to?
I wonder how the ArmaSpec compares to JP Enterprises model.


- Doesn't this ArmaSpec device have an o-ring on the face where the BCG hits it?

Are you guys concerned about that O-Ring wearing, needing replacement, or even worse; possibly failing at an inopportune time and jamming up the action?

I'm curious to how it compares to JP too. I have one JP setup, it runs great.

[deckhandmike]

I’ve wanted a JP setup but haven’t been able to justify the costs.

[deephouse]

I think there's some videos on YT that compare the two...

[MarikinaMan]

I finally test fired the rifle. I did some drills and went through some 200-300 rounds.

After switching to a heavier weight, the direction of the ejection pattern didn’t change. It’s used to throw at 2 o’clock, about 15 feet. Nows it’s 2 o’clock at 5 feet. It looks like its mildly tossing the shells forward.

I’m gonna stop playing with it as I think if it if I put an even heavier weight, it might stop feeding.

Funny, I made a thread the past week concerning the Armaspec Silent Buffer. Missed this one. I did my normal research regiment after coming across, because I had a gift certificate. You actually have Armaspec’s “captured” version, they call The Stealth. I ordered the non-captured H2 weight, for $44. And I like it. My previous setup on many other rifles, was in fact the Spikes T2 and Wolff Xtra power spring. Which cost about the same as this new Armaspec I have. The Stealth model you have, is a bit more(around $80). This is still far less than the JP version. I cannot speak for the JP, but I can say the quality of the Armaspec is outstanding.

Of course I’m not expecting any increase in performance, as my setup has worked very well on many rifles for the last 7 years. A buffer is unlikely to change trajectory. That is pretty much ingrained by the bcg, extractor, ejector and machining of the outlet on the upper. The buffer helps control speed of the bcg only. As I said in my thread, the Armaspec for me, was more about the compactness & efficiency. Also the high quality of materials. And while I’ve been quite used to the familiar “Sprong” from my ARs, it certainly won’t be missed!
