vltor a5 kit on a middy?
Ive been thinking about buying myself a mid-length and using it with a Vltor a5 kit, but Vltor specifically states that it must be used with a carbine gas system. However i know for a fact that many people do use it with a mid length and have no problems with it. The only issue I can see arising is due to the fact that a heavier buffer requires more gas to move, and the mid-length pushes less gas back into the gun. So at a lower elevation problems could potentially arise when using less powerful ammunition, such as subsonic ammunition, yet of course a suppressor will also increase the amount of gas forced into the chamber and thus help to correct the problem. So I'm essentially wondering, are there any known drawbacks or problems with a heavier buffer on a mid-length? Anyone with a Vltor a5 buffer on their mid-length who has used cheap ammunition or subsonic rounds and can attest to them having worked ok? Thanks for your help in advance.

Hey buddy hit up the search and you will get a metric ton of info on that. The short answer is the A5 will work fine in a Middy I run one with a A5H3 buffer and it chews any ammo. The A5H3 buffer is heavier than the A5H2 that is sent with the A5 until.. Depending on what your shooting and the components you should have no issues.

search is your friend, lots of discussion on this subject, my 2 cents is it does work with a 14.5 middy using a h3 with regular rifle spring but I was also shooting my practice reloads with 24.5 tac/or 2230 which is pretty warm 223 loads, gas port gets pretty critical for that combo. just buy a BCM ELW barrel and have no worries that the ports correct

I run an A5 system with a 16" middy with no problems. I'm using the standard A5-H2 because it's what you get if you buy the A5 as a kit rather than buying the different pieces separately, but I'm going to step up to the A5-H3 and see what happens. I recall seeing reports of problems with using the A5 on 14.5" mid-length guns, but those were hit and miss. There are lighter buffers than the A5-H2 you can try if you're having problems with short stroking or failure to lock open after the last round.

The A5 will run anything from a pistol length gas to a rifle length gas, provided the gas ports are sized properly.
The standard weight works well, but I prefer the slighter lighter A5H1, as it matches an H2 buffer in weight, meets the minimum weight to prevent bolt bounce in most cases, and exhibits minimal nose dive during return to battery.
The cartridge characteristics, barrel length, gas system length, gas port size, buffer weight and action spring all work together to determine the behavior of the operating cycle.
It all works together.

I don't have a lot of time behind it yet (maybe 600 rounds), but my 16" middy with standard weight A5 runs very well.
Not failures to date with .223 spec 55gr, 62gr, 69gr and hot loaded 77gr.
Everyone who shoots it is amazed at how the minimal the felt recoil is. Very little muzzle movement.

I run a BCM 11.5 with a A5H2 and recently tried a 14.5 middy on the same lower using Remington .223.
My VERY first shot (new BCM barrel), the case did not eject properly causing a malfunction.
the remaining rounds (around 30 for zero and test) fired and the function seemed sluggish.
I bought a A5H0 buffer and will try that tomorrow with the same .223 and some XM193.
I also switched the green Sprinco for the factory Vltor A5.

The A5H2 runs really well with my BCM 14.5" middy, but the A5H3 gave me some problems and the A5H4 was pretty much a no-go with lower powered ammo.

I run carbine, mid, intermediate and rifle lengths with zero problems. Most current favorite is the rifle length set up.
