    Hydraulic recoil buffers

    These never seem to have caught on in any significant way, although someone must be buying them as some companies are making them:

    So, what are the pros and cons of such a device? Any chance of a fluid leak?

    I remember them being one of the many gimmicks offered to correct what we now know to be massive over-gassing buy idiots who spec out barrels.

    I can't think of a legit reason to introduce such an item to a system that doesn't need it when gassed correctly.

    I've only used the enidine (first one broke). It works to soften the recoil impulse a bit, but also requires a very definite tug to lock the bolt back manually. Based on my sample size of one breaking (it was replaced); I've just shied away from them. The replacement has not broken but then I have not used it much as most of my rifles have the A5 system, which works well for me.

    Always seemed like a solution in search of a problem, to me.

    When they fail, does it cause stoppages, or does it act like a regular H1 or whatever buffer?

    Edit: I mean in a semi only gun.

    When mine went from the article, it was while shooting a stage at a 3gun match. It still worked, I just noticed rifle recoil felt weird. Swapped it out for H2 to finish the match. Replaced it with Crosshair hydrualic buffer still going strong.

    For less money, you can get a complete A5 setup.

    Why I’m interested in this thread: I’m “building” a game gun. Previously, I’ve competed with rifles that are suitable for putting in work. Usually whatever is found at my bedside. Setting up a proper game gun has created an interest in such things as muzzle brakes and lightweight carriers. I have a colleague that swears by hydraulic buffers, including in a duty weapon (not my style). So I might put one in this game gun, along with the first non-mount brake I’ve had on a AR since 05. I’ll take a regular carrier to a machine shop to take some grams off the tail, because I’m not ready to make a leap to exotic materials.

    Jeff, what brand buffer do you recommend (ITAR does not affect me)? Do you use a regular Colt spring? Are these doodads compatible with a non-full mass carrier? Is a hydraulic buffer useful if I already have an adjustable gas block, or is it a waste at that point?

    I have both kynshot and crosshair buffers in rifles, I prefer crosshair now. I use stock spring. I don't know about low mass carrier. But for me to get lightest recoil, hydrualic buffer with comp muzzle brake and adjustable gas system. Piston or DI, I have hydrualic buffers in most my guns. Both adjustable gas and standard gas, adjustable gas way to go to.
