Alright gents, my goal here is to figure out which one of these buffer systems is better and why. I have neither and have shot neither. All my AR's have a normal carbine spring and buffer in them. So I'm asking, for those that either have or have shot both, to enlighten me on which one should I purchase for my ongoing build. Any information would be appreciated.

JP for suppressed quiet build

A5 for ultimate reliability

Which one is more important to you?

I agree with the above.  They are not comparable and are not trying to accomplish the same thing.

I used an A5 buffer for a carbine build recently.

Honestly, if the rifle is properly built, I cannot see a tangible benefit for using an A5 buffer over a properly weighted carbine buffer and quality buffer spring.

I do think the JP silent capture buffer is interesting, but have no experience here.  I might give one a shot if I build a rifle with an adjustable gas block.

Run AN H3 Carbine buffer 5.4 oz - it will slow it down.

If your carbine system is working reliably and the gun is not seriously overgassed, (like bolt bouncing or tearing cartridge heads on extracted cases) then neither alternative makes much sense to me when reliability is your ultimate objective.. I don't know what the objectives in your new build are.  If it must be reliable with all available ammo, then take care about stiffer springs and heavier buffers.

If overgassed, the proper remedy is an adjustable gas block tuned to the ammo you shoot,  or perhaps alternatively a slightly heavier carbine buffer, like an H2, just to slow things down a bit.  It's better to be a little overgassed with hot ammo (full power 5.56) if you also shoot weak bulk ammo or lower velocity match ammo, so that you can reliably cycle everything.

Just one opinion.

regarding the A5 vs carbine; what i noticed was that when using similar buffers weights, the rifle length spring in the A5 made for a smoother impulse feel when used on the same carbine upper/barrel...that was a noveske 12.5" double chrome lined.

i didnt not notice the ejection pattern though.

In my experience , I received the same result by simply changing from a stock buffer spring to a quality spring from JP or Wolff.

This.  If you run fine now, the A5 offers nothing.  If building a new gun go for it.  It offers a different way to the same end.  

The JP SCS is not intended to be a battle rifle part.  It has more parts, but I honestly see no way it can come apart and fully trust mine.  The spring is weaker to begin with, so you need adjustable gas to get any benefit from it.  Its more of a competition gun part, but obviously is quieter with adjustable gas and a silencer.  I have two.

The only rifle loaded in my house is "mil spec" like with no extra screws or springy thingys.  But, I would have no issue facing sasquatch with my 3 gun rifle.

haven't used the A5 system but I really like the JP SC,  makes for a very smooth shooting carbine. Its nice that you can kind of tweek the system for your needs never really had an issue with sprong noise, but would definitely use it again,

while not a mil spec type of buffer, its fairly simple design that I really see nothing going down on it outside of occasional spring replacement

You may like the A5 because it allows a longer LOP.

I put a SR-15 upper on my A5 equipped lower and it ran just fine.

I also run a SCS on one of my 14.5" SR15 E3 guns, and a suppressed 8" Noveske 300BLK.

They do a really good job for keeping your gun quieter.

I like the JP SCS not just because its quieter, and it is noticeably quieter, because the gun functions more smoothly.

This.

My match rifle with LMOS carrier and SCS, I can't feel the rifle cycle.  It is fast, but gentle, if that makes any sense.

When I shoot a standard carbine now, I can feel the carrier/buffer bottom out in the rear of the receiver extension, and then return back forward.

It is difficult to quantify but it is an entirely different feel.


I haven't used an A5.
