Enidine Hydraulic buffer. > Rifles, Uppers, Lowers, Barrels, and more

I'm interested in putting the Enidine Hydraulic buffer into my 16" M&P15. I've been told by a knowledgeable guy that these work well do reduce recoil and improve compensation. Has anyone else used one of these? I'd appreciate your overall opinions about them before I buy one. Thanks, guys!

I've got one in my lower (still waiting on my upper). And my brother and me switched his M&P15 upper onto my lower to test out the Enidine. The main difference that I could see is that it virtually eliminated the muzzle rise 100%. I'm happy with mine.

If these are hydraulic, I wonder how they function in a place like Alaska or anywhere else below freezing? I would think it would slow the flow of whatever fluid is in it and maybe cause a short-stroke?

Iv'e got one on my .458 SOCOM and it seems to have worked pretty well so far. The .458 is in the shop right now for other reasons.

No. Even if the hydraulic fluid freezes solid, it will just act as a regular non-hydraulic buffer.

I ran one in a 14.5 carbine for some time. It worked as advertised... it was a notable recoil/muzzle flip reduction.

I changed it for a H2 buffer just because I didnt want anything breaking/leaking inside my extension tube/rifle action that may stop my gun to go bang in a stressful situation... you know, Murphys Law.

While the Enidine is longer than the regular buffers so it has room to compress, even if it does not compress at all you still have enough room to charge the weapon, expend a loaded case and load another round. It can lso hold the bolt back half assed on an empty mag. The extra length is not much and I have never heard of cold making th ebuffer work impropperly.

Well you have less faith than the US military. They use Enidine buffers in the M249/M240 as well as the M2 soft mount and many, many other military applications. Even if the unit leaked it would not cause a malfunction... it would just, in escense, become a dead weight H2 buffer. They DID have a run of over hardened shafts over a year ago that would break but as far as I know that issue was resolved.

If it all leaked out/froze up, wouldn't that lead to bolt-bounce as the Enidine uses hydraulic fluid vs. sliding weights as a "deadblow" mechanism? or am I confused.

People have filled regular buffers solid with lead shot and not suffered bolt bounce. It is not a certainty, no.

IMO not using an Enidine is like not using an Aimpoint because "battery powered optics might fail." If it worries you that much just buy an MGI. Its supposed to be even a hair better than the Enidine but at a higher weight and price (mind of like a Vortex vs a Phantom flash hider) I have heard one of those (MGI) filled with blowback crud and needed to be disassembled and cleaned to get it working again. Everything has a drawback.
