I cannot believe my luck or these are POS.

I broke one that was in a piston gun on a F/A lower. Well guess what, got the replacement and have been running it on the DI 5.45 upper. Fucking thing shit itself again, probably around 2800 rounds.

While Enidine stood behind their product the 1st time, the second failing leads me to believe its just a shit product.

Oh BTW anyone who says if it breaks my gun will still run=FOS. Stopped the gun dead in its tracks

Latest failure and a shitty pic



earlier failure




Note they failed in the same place

Just run a heavy buffer and call it a day?!?

What would you suggest I run for a a 10" SBR on F/A in a carbine gas system with a bolt bounce problem?

a 9mm buffer or even heavier than 9mm I think there is heavier than that.

Maybe one made of solid tungsten.

Its not solid, but its mostly tungsten, still doesn't work, need the articulation of the enidine

The hydro buffer is a band-aid fix for bolt bounce.  Fix the problem instead of masking it.

Bolt bounce is when the bolt bounces back when trying to go into battery. 87Gn has some videos about it.

It should be called carrier bounce.  The carrier slams into the barrel extension, bounces back a fraction of an inch - just enough that in full auto it prevents the hammer from contacting the firing pin hard enough to ignite the primer.  I mention in full auto because the carrier trips the auto sear. Odds are slim someone is pulling the trigger fast enough in semi auto for this to be a problem.

too much gas is the problem.
New barrel with gas port drilled too big, old barrel with gas port eroded, out of spec/tight chamber

I run my M16 2 ways. Shooting crap ammo and its an H2 which cycles and gives me 750 to 800 rpm,  I use an MGI rate reducer when shooting decent ammo and still get the same ROF. 11.5" gun with or without the HALO. I have zero issues..

I decided Enidine was junk before I broke one...

Never did fall for one.
I would buy a h2 buffer or H3 or even 9mm with wieghts

Llike bigbore said, you have a gas problem, not a buffer problem. Fix what's wrong.

Why not swap the barrel then or get an adjustable gas tube to reduce gas pressure?

Someone should design the product so that it will function with an overgassed gas system or eroded gas hole..I dont know why more thought on how certain functions that can be hard on parts isnt addressed to make the part work no matter what.So although ultimately it may not be the buffers problem the buffer for that price should be made to take it no matter what.I have heard of enedine buffers failing with less of a round count on other rifles.Maybe a heavy anti tilt buffer used in piston systems may help by having more stable contact with the carrier.

As noted above and shown here is video a couple of months ago, a 9mm buffer caused the worst bolt bounce, i.e. heavier is not necessarily better.

I didn't post this to get help. I posted to show what can happen to a enidine buffer.

I have  10" barrel with the longest gas system available, (custom) with the gas port the smallest it can possibly go and still cycle a round. The bolt bounce problem still exist, Its also present on a Tok upper and that thing is defiantly not over gassed.  

So no matter what most think sitting behind the computer, the eneidine buffer was working to fix the problem of shooting a round not designed for the  AR series. The enidine is a lot cheaper fix for a range upper on a F/A lower than buying a custom upper with gas block-that's not the point.


Again I will fix the blaster upper/range toy when I burn it up, this post was not a "help me" post but a information only and the second post was made in jest, to highlight he fact that most will post a fix, without understanding the problem or have full information available.

Im not spending more money on a cheap blaster upper that is a range toy, especially to shoot corrosive ammo.

Its usually easier/cheaper to do things half assed than to do them properly.

Whatever you do, don't try the AAC Rate Reducer either. Although the gun ran beautifully, it broke after around 700 rounds.

If they give you another one, could you have a small collar of pipe tig welded around the neck?  Too bad a poly bushing could not be placed behind the head to buffer the buffer.

How has their customer service been?
Maybe have them send you two so if the next one breaks you have a spare?

I apologize for attempting to help. You should probably in the future address the actual problem instead of complaining that your band aid fix failed.  Some of us know what we're talking about.  You aren't the only person here who has had an over-gassed short barrel F/A.  The fix is less gas, not more buffer.

I was thinking about getting one, until I saw a pic of a failure. It may have been your failure/pic that swayed me to stay  away from these.

I use H buffers in my ARs, no issues at all...

Learn something new everyday, excellent post describing the problem, rather than the symptom.

So since its a hydraulic buffer, does it leak fluid inside the receiver extension every time one breaks?

9mm buffer won't do it alone... That's how my Grendel was. I added a LT stiff buffer spring, good to go! $30 is worth a try.
