Must have item!
Excellent. Once you install these buffers, and tune your AR with an adjustable gas block to use the minimum amount of gas to cycle, you will, overtime replace the open spring style on all of your AR's. They are that nice. You will not hear and the spring rubbing on the tube, and instantly feel the crisp cycle of your AR. I have these in every AR that I own.
Doesn’t even let me charge it back do to the end p
This doesn’t even work with my 9mm bolt carrier group it’s literally won’t charge back because it’s literally solid steel I’m not impressed trying to get my money back don’t waste your time if ur getting it for a AR9
9mm buffer
I really like this product. It was very easy to install and the gun now runs much smoother and much quieter!
Great buffer system
Fit was great and excellent quality
Less is more
After 100 rounds and broken in, and two cleanings I can say I love not having the rattle and grinding in my ear as well as the additional unbalanced weight in the buffer tube. I used a little clp in the spring and shaft to quiet it down even more. The only drawback for me has been when I remove the upper and have to hold back the buffer a little but it’s not that big of a dealbreaker… read more for me.
Sweet
Love this thing.
Smooth & quiet
I was surprised at how well this buffer worked. It's quiet & very easy to install. I'll be getting a few more for my other rifles.
Best option for buffer in your AR10 build
If building a AR10 I suggest going with one of these instead of a regular AR10 buffer. Cost is about the same as buffer when on sale
Great buffer
Noticeable difference between this and a standard buffer.
Silent Buffer
Due to the near impossibility of finding 6.5 Grendel ammo I haven't used this yet but the quality looks great and the installation was simple.
Very Good Product
Great price point. Easy to install. Works as advertised. Quiet and smooth.
Great product at a good price
A+++ product, shipped quickly at a good price
SMB
Great service and fast shipping. The spring seems fine. Not sure on its longevity, but it is definitely more quiet.
Great product
Does what it says, definitely runs a lot smoother over traditional buffer system, and does it quieter.
Very smooth and quiet
Installed this and was amazed how much quieter the action was... no more boing sound that I had with the standard buffer and spring. Will buy more as replacements.
Sounds Good
I'm still purchasing parts for my AR build, but I've recently used this on a friend's AR and it def help keep that thwang sound to a minimum or none. Good build quality, feels like it'll hold up for a while, looking forward to using it more once mine is completed. Def recommend.
Not sure how this is supposed to work
I bought this for my ar9 and after reading about it I asked customer service, who responded right away, if I had to remove the weight off the back of the bcg and they said yes. After removal their is a big gap between the bcg and buffer causing the bcg to slide around. I took out the buffer retainer but their is no way this will work because it leaves a massive amount of back space… read more for the bcg and you can't take the gun apart to clean it. Very poor design, any stars you see is because Victor and the customer service team is awesome
Armaspec mitigation buffer!
What a difference from the standard carbine buffer to this beauty! Price it’s right too!
Works great
Works great no issues
Excellent
Smoothest buffer kit I've ever used. I have Armaspec in all my AR's, and I don't see that changing.
Smooth and Silent.
Great fast shipping. Went right in. It does protrude a little so be careful mating the upper and the lower, but works great and well worth it.
Sound Mitigation Buffer works as expected
It’s a well designed sound reduction device. It you suppress your weapon, often times the only sound you’ll hear is the action working. While you’ll still have most of that noise, the echo and squeal of the buffer spring rubbing against the buffer tube is effectively removed. I would recommend this upgrade.
Works better than expected!
Quality materials, easy install. The little flag on the end of the spring guide is a very nice touch! Spring noise is gone as advertised. I got the H2 and it smoothes out my 10.5" pistol so well. The buffer has a rubber pad on it that extends past the receiver extension when the upper is removed, and it has to be pressed back in for the upper to close. No big deal. Overall,… read more 9.5/10, and I'll be getting another for my other rifle as well.
Haven’t used it yet
My 9mm bolt doesn’t not have an open chamber so I can’t use it yet.
Outstanding Value
Quiet and effective. Replace your current setup with this and smile.
Have 2 of Armaspec Sound Mitigation Buffer h3 and the 9mm... only a small issue
the rubber ring goes past my buffer retaining pin and makes it hard to open and service the rifle. it works great but I have the Armaspec Stealth Recoil Spring (Armaspec SRS) and it works better and great performance spend the 30 dollars more
Awesome product for the price!
Had no problems installing it and my rifle doesn’t have that irritating sproing noise anymore. I’ll be getting theses for future builds.
Won't work
I have a juggernaught 9mm if you a weighted bcg then ths wont return.
Smb-9
Good looking product.Not compatible with all BCG.If your BCG is solid on buffer tube end it won't work.
Great product and price
Very solid product and reputable company. I will definitely be back with my friends.
Kaw, strike, armaspec
great!
The cure for AR-9
This fixed the feeding problems with AR-9
Awesome product
The item works as described. Fits well and is 10x better than a traditional buffer system.
Works excellent
Excellent fit ..thank you guys.
H2 buffer
Installs easy, quiet and shoots well ,worth it in my opinion considering only a few dollars more than the traditional style
Seems high quality
Seems rugged for the price. Only thing i dont like is when the uper and lower are separate the rubber ring rides up against the buffer retainer pretty hard.
Works great!
I love this buffer. I use it in my suppressed 300blk AR pistol. Its really does help reduce overall sound of the gun.
Love this product
Armaspec did a great job with this. Even better is the pricepoint. You can pay top dollar for a recognized traditional buffer and spring, or get a better silent system for less. I’ve bought 2, one for my 5.56 and 9mm AR. Will buy for every build.
Fantastic!
Bought one for my AR15 and what a difference. Smoother cycling, no twang, and no spring/buffer riding the inside of my tube. Liked it so much bought a second for my ar9.
Cool design but flawed
This is an interesting replacement for a traditional buffer and spring but it has a flaw. The rubber piece when used with a retainer spring rides too hard against the retainer and makes separating the upper and lower difficult to the point where I had to wrench it open and when I did so the rubber o-ring popped off.
Good to go
Really works, can't go wrong with this device ! Luv it!
