Not that my mp15t(5.56) kicks that bad, just thinking of lowering recoil to reduce wear on optics and for follow-up shot accuracy...any tips here on what i should be considering? saw enidine makes the AR-RESTOR kit for carbine...

I would really like to hear from someone who has bought one. I would like to know myself how much it slows down the rifle and how much wear and tear it stops.

Damn, car insurance due and my last ammo purchase took a bigger chunk than i had budgeted for, otherwise i'd go ahead and grab it and do my first product review since i just joined the site (iv done reviews before but new to civilian ARs)...hmmmm, the credit card is whispering to me............

try an H2 buffer, I think the hydraulic buffers are to slow down the cylce rate on full auto's

not really lookin at cyclic rate, mine won't be full auto -- just want minimal recoil/muzzle movement to reduce amt of time putting second round on target...

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.

excellent, thanks root...that's kinda what i wanted to know, someone who had used it and actually SAW a difference...kinda new to this forum, haven't gotten my profile updated, but i'm guessing as an Army vet, you know kinda what i'm looking for (my bro is Army, i was Marine -- fun christmas dinners...lol)...do you mind me asking which version you have, as well as other improvements you may have made? mine is SW MP15T, and i'm just starting on her...she's my first actual AR

quick follow-up...did you use the stock spring, or should i get a dif one when using the enidine?

Rootbrain...thank you very much. I wondered about this, these are on my list for this year.

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

Zip, at least in Tapatalk on iOS devices you can press and hold the link then choose to open it in Safari. That will open the link correctly.

man you guys are awesome...not only am i sitting here wondering if i should put it on the credit card, rather than just answering my question, members are gonna go ahead and BUY it to test it...this forum has officially made my top choice, though the HK guys are pretty cool...you guys rock! can't wait to hear back from ya, JaPes...

That's odd Bill it didn't work for me. Opened in safari but not to the right page. Let me check my settings.....

I bought one for my Sport and I didn't see a lot of difference in recoil. The recoil was somewhat lighter, 10% - 15%, but it wasn't a lot. But I put one in my LR 308 and it made a big difference in that rifle! Everyone perceives recoil differently so all you can do is buy one and try it out in your AR and see how it works for you.

The one in my Sport has worked fine for almost a year and I've had no problems with it. But once it wears out I won't buy another one for my AR. I'll try different buffer weights and springs.

The AR-Resistor arrived today.







The highlighted features quoted from the packaging:

• High Impact Striker Cap
• Smooth Running Nickel Plated Rod
• Installs with standard hardware, no special tools required
• Black Oxide Finish for Corrosion Protection
• Polyurethane Bumper

The feature that got a laugh out of me was the "no special tools required". Well duh.

I compressed the piston between my finger and thumb. There wasn't much resistance to overcome. When manually cycling the bolt via charging handle, there's a little extra "squish" at the end of the bolt's travel.

I'll try it out next weekend and let y'all know how it feels. I'm skeptical it will do any better than an "H" or "H2" buffer.

Q: What's an indicator that you may have an AR15 problem?

A: When you have a carbine, H, H2, & Hydraulic Buffer in your range bag.

LMAO.

How does the length compare with an H-2 ?

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.

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...

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. 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. 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.

Forgot about that! Lol

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 plan to get to test it out next weekend.

Tune in next week. Same Bat-time. Same Bat Channel.

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

Ahh. A word mostly always mispronounced, and widely unknown to the majority of the public. Such a fun word to say though.

I was at a local range the other week and met a guy who had just installed one. For the life of me I can't remember the brand. He offered to let me test drive a few rounds and I can say "wow, sure feels different and very nice". It wasn't that the recoils was that much less (how far down do you want it from stock anyway. But it was smoother and the twang was gone. Felt like much better control but I didn't have a whole lot of opportunity for investigation. My intial reaction was very favorable and time/budget permitting I will investigate further

Hmmm...i'm actually impressed how nice of a thread this has turned into...very pleased with the feedback and input, plus the best is yet to come with JaPes' upcoming review...THIS is the kind of thread that has already made this my fav online resource/forum for info and advice with my new AR...thanks guys

Tick tock tick tock I shall be watching the clock.

Just a thought. I'm wondering if there is a way to hook up a scale (like measuring trigger pull),to measure a difference that way ??? It would have to be mounted in/on a bench rest and it would need something more like a fish scale hooked to it to "catch" the pull weight. Hmmm,hook a fish scale (that has a weight catch,like for trigger pull) to the rear sling mount. Attach the other end to the bench rest and just balance the weapon enough for the pull weight... ??? It's not like it has that much kick like a 12 guage or 308. As long as it's done the same way for testing,that would be a rough guesstament as to how well it might cut down on felt recoil.

....hay,I'm just trying to burn up some time waiting for next weekend to get here. Grover is busy doing taxes and feeding their "petting zoo".

No worries. I trust your judgement on the felt recoil call.

...off to the Bat Cave,I need a cold one.

I myself could never get used to the twang...it always sounded like a Red Ryder to me! Thats why as soon as I could I switched out for an M60.

Sorry for the delayed response.

Other improvements, I did my own low mass trigger job and installed this hydraulic. Added RDS and reticle scope. 'Bout it for mods. I have Colt 6920.

I used the stock buffer spring, no reason to change.

There have been reported failures, but in reading them, most are a few years old. Most are people that haven't used it, but "know someone that had nothing but problems". Mines perfect on my 5.56, I suspect it would work even better with .308 or 300 blackout. Of course, not shooting much now because of ammo situation, so will be awhile before I really know how "worthy" it will be.



Rootbrain

If ammo shortage continues I might have to go back to shooting a Red Ryder. I haven't shot one many many years.

That's because it was so noisy and a hand full. Sure did make the BG's duck and cover.

I've been finding some mixed reviews about them. But you know how reviews can go. These were mixed from broke and hated it to wonderful and really settled down the recoil and would get another one. ?!?!?

So we'll have to wait and see what John comes up with. HIM I do trust. We'll see if it's a go and add it with your experience.

i'm so impatient...bought one from a guy on the forum NIB for a good price, so its worth the gamble...lol...i'm gonna check it out too, and see if JaPes review reflects my personal sentiments...although, i'm not as experienced with AR platform, so his input means more! lol
