Hydraulic Buffer?

John, I really want to hear how it does... I wonder if it starts to build up pressure as it cycles?
 
I really hate how tapatalk screws up links to brownells on the iPhone!

Was hoping to take a look at it as well....

**edit...bookmarking that one for a purchase** :)

I've found with the Tapatalk links on iPhone to brownells tap the link once, let page open them exit the page. Return to Tapatalk click the link again and it goes to the page. I think it has more to do with brownells mobile page than Tapatalk. Give it a try that's what works on my iPhone.

How does the length compare with an H-2 ?

Here are my quick measurements using a postage scale and my digital calipers.

Carbine Buffer: 3.0 oz , 3.259" long.

H Buffer: 3.7 oz, 3.244" long.

H2 Buffer: 4.6 oz, 3.329" long.

Hydraulic Buffer: 4.2 oz, 3.649" long uncompressed, 3.252" long compressed.
 
Hmmm...within an ounce wont be noticeable...im really curious about the "follow-up shot" factor more than anything...i would sacrifice a full pound of weight for dependability and quicker, accurate shots...but then again, im used to carrying a much bigger rifle...lol

The weight I listed is the static weight of the buffer. We're all used to using buffers of static weight: carbine, H, H2, etc. The hydraulic buffer changes the dynamic because hydraulics is a force multiplier. The bolt not only overcomes the static weight of the hydraulic buffer, but also the resistance of the hydraulic piston. As I compressed the piston by hand, the force required increased the closer the piston came to bottoming out.

I've read forum posts about hydraulic buffers. The issue I have is gaining a frame of reference on which to interpret the forum post author's report of a completely subjective feel. "Recoil feels softer." It's hard to judge that statement because I do not share the same frame of reference as someone else as to what recoil is "soft" or "hard". It's akin to different people having different tolerances for spicy food. "Follow up shots are quicker." How fast.

Is the perception of an improvement true, or is some sort of placebo effect or denial? Spend $90 on a hydraulic buffer instead of a $15 standard style buffer, and you'll want it to work no matter what. I'm going to have to keep this in mind when writing up my subjective opinion. If my buddy comes to the range to test out his own AR15, we'll try the buffer in his rifle too.
 
When installed is this addition visible JaPes? If not and your buddy joins you you could do a blind study. He walks away. You either install or not. Hand him the weapon for evaluation. He takes notes. You each repeat this process a few times. That way there is no perception involved KNOWING its installed. It's only a feeling the gun gives when fired. If you limited shots to 10 per round the entire study could be done with 80 rounds...40 per shooter. 20 with and 20 without - without knowing the order.

Thanks John. Now for the biggie. It's yours and up to you. Is there any way to mark the rod so we can tell how much of the piston rod is actually used taking up recoil or if it bottoms out ? Like putting a mark on the rod with a magic marker for a couple 3-5 rounds. I don't know if a magic marker would stick or even rub off to let us see. Like I said,it's yours and up to you.

Are you using a stock spring ? Any chance for a spring coil getting "ate" inside that piston on impact ? (S do happen). I almost bought one but found a couple H-2 and an H before prices went totally crazy. That one was a bit high and new yet.
 
The rod is nickel coated. I'll try to mark the rod, but I'm not sure if it will work out. I'm using the stock buffer spring. The rim on the hydraulic buffer on which the buffer spring seats is similar to the stock spring. If the buffer spring does slip off the rim, it would be most likely due to a spring issue.
 
Maybe try a dry-erase marker on the piston. Try and dry it off and color in the entire visible shaft than fire a few rounds and check it. Should be clean as far as the piston went into the housing.

The only problem I see with this is the probably lack of the standard buffer *twang*
 
personally, i always hated the "twang" anyways...first time i fired an M16 in boot camp, i thought my weapon was malfunctioning, all i had ever fired before was bolt-action hunting rifles, wasn't expecting the springy sound...you get used to it though...
 
I bought one of the Endine, everyone advised against it on the M4CARBINE site, but works great for me. Cuts the recoil in half. The "bolt bounce" that is mentioned seems to be improved and muzzle rise is diminished so aquiring target for a second shot is quicker. I can see shot impact on first shot also, so it gives me a better idea of where the second shot should go.

You're right, cyclic rate on semi-auto is not an issue really. The others are, and this fixed them for me.


Sooooo. If I add one to one of my AR's with the FAB GL-Shock stocks,my AR should feel like shooting an air rifle. :o LOL. I have been thinking about getting one to try out too. I saw a couple different ones on another web site that were really pushing them. Weren't any reviews to go by though.

Said that (first part),to get a smile outa Grover,JaPes and the rest. With all the "hoarders" getting the prices jacked up,we need a small chuckle now and then. :o Come on JaPes. The suspence is driving me crazy (no worries,short trip).

I went from the M-14 to that "twangy pony" in late basic at Ft Lewis. And you did get use to the twang next to your cheek.
 
Lol...its amazing how u get used to it so quickly, then when u go for 5 yrs without it and fire an AR then, makes u feel like ur back in boot camp immediately...lol...so is this hydraulic buffer gonna ELIMINATE the twang, or just reduce it? Might be an added benefit to increased follow-up shot time...

From what I've been reading,it's actually made for heavier rifles too. But can also be used in the 5.56 and is supose to help with reduced recoil. I thought I saw a heavier one for 308.

It should help take out some of the twang,but I doubt it will remove all of it.
 
I figure the twang is because of the extra room for the spring to re-extend, kinda like shaking a slinky. If it's like I imagine, and there's not a spring, I would guess that the hydraulic buffer would have more of a whoosh..... onomatopoeia
