    It's 1.75" longer than a 11.5" with an A2 FS'r. Here's a pic of both of my 11.5" uppers.



    Here's the same 11.5" w/KX3 with my 14.5" LMT SBR.

    These are my two 11.5" uppers. The haters think that's way too long. I carry this gun around with 77gr BH so barrel length/velocity loss isn't an issue.


    gotM4,


    Could you give me the specifics on the LaRue rail on your 11.5"? Is it a cut down LaRue 12.0?

    A friend and I were discussing a SBR project with a 11.5" barrel + KX3 and asking LaRue or having a machinist cut down a 12.0" rail. BTW what kind of barrel did you use on that upper? Great looking SBR's. Any help would be greatly appricated.




    Thanks,

    The bbl in the Larue 12.0 is a CMMG 11.5" chrome lined 1x7, the one above it is a M1sales 1x9 non chrome (I got on trade). The Larue 12.0 was cut down about an inch by Harlan of Hardgear LLC (he's a member of this forum) We basically measure it out and marked where to cut it so that the flats of the KX3 would be under the rails. I used a strap wrench and a peel washer to mount it instead of using a crush washer. I use a Enidine buffer in this gun and it has very little recoil (even less than my 14.5" LMT).

    Harlan cut the rail with a hack saw and cleaned up the cuts using a bench mounted sander and finished the end with flat black Norrells.

    It adds around 2.4" to 2.5" to a barrel's length so that 11.5" becomes a 14".
    This is why you see them permanent attached to 13.7" barrels for a total length of 16.1"

    Thumbs up The PIG

    I noticed less noise inside, a lot less recoil, and no difference in flash. Its well worth the money.

    I got the KX3 standard on my Noveske Infidel 13.7''. I've had it for about 2 years now.

    I can definitely agree that the pig does an excellent job of directing all the propellant gasses forward (not a hint of powder-burn or concussion when shooting). I'm afraid I do have a few beefs with it on my setup though:

    1. I think it was my mistake to have it on a 13.7'' barrel, seeing as how it is a little chunky and a longer barrel will bring that weight out further. Between the 12'' VIS rail and the KX3, my rifle is pretty front heavy.

    2. I had myself convinced that the extra weight on the front end would help reduce the muzzle climb and recoil (makes sense to me, anyhow: more ass = less movement...) Here's the thing that finally occurred to me though: with the KX3 directing all the gasses straight forward, with no lateral dissipation, the recoil felt actually seems to be greater than that of my work rifle.

    Again, I think these are only really issues with my setup. The KX3 is a great product for several applications (shooting indoors / shooting in close proximity to others / helping properly cycle gasses on SBRs, etc), just not for the setup I'm running.

    Anyone else have the same notion of increased recoil with the KX3?

    I don't see that on mine, but mine is a little different as my barrel is a 12.5"
    Perceived felt recoil is about the same as it was in its 16" form.

    You're pretty much right on track T-Dot. The force of all the propelant gasses exiting the front of the rifle, rather than laterally, can increase felt recoil a bit. If you apply the physics to it, the device is designed to add more force to the BCG to increase dwell time and gas pressure, so in turn, yes, you are going to get a little bit more felt recoil because of not only that, but again, what you were speaking of, the gas being expelled directly forward.

    Edit: I don't really want to speak in absolutes, I said originally that it does, but changed it to "can" because as with anything, there are other variables that come into play that may negate or add to felt recoil.

    Thanks for the replies.

    Yeah, I really can't speak to the recoil effects on a 12.5'' barrel since I've never experienced it. I can imagine that any drawbacks in recoil are far outweighed by the advantages at a 12.5'' barrel length.

    Mega: when you say that the felt recoil on a 12.5'' were similar to the 16'' form, I assume you're saying you've used a KX3 on a 16'' barrel? I'm interested in how that shot: was it noticeably more unwieldy than a 16'' without the KX3? The reason I ask is that my 13.7'' is a little front heavy and I'm trying to figure out if it's the KX3 or the 12'' VIS upper that's the culprit...

    viperashes: Thanks for the reply. I guess the question I should have asked myself was "Does a 13.7'' barrel really need as much help as a shorter barrel with cycling gases?" I'm imagining the answer is no.

    Next question: what barrel length warrants a KX3? My first vote goes for 12.5'' (like I said, the 13.7 doesn't seem to need it).
