Keeping a M4gery over 30" OAL

[J_Rock]

I found another option a KAC M4 QD Flash Suppressor with a few crush washers.



"M4 QD COMPENSATOR, WITH SHIM KIT, $89. THIS DEVICE (PINNED AND WELDED IN PLACE) WITH A FEW OF THE INCLUDED SHIMS PLUS A CRUSH WASHER IS THE CLEANEST WAY TO MAKE A 14.5" BARREL INTO A 16" BARREL. REALISTIC, TOO, AS IT IS WHAT SOCOM USES. BACK IN STOCK."

Yea but why would you want to spend $100 extra for the option to mount a suppressor? (CA: keep dreaming) Unless you are one of those uber-tacticool guys who absolutely needs to have exactly what SOCOM uses.

Because I'm making an M4gery. Not just some carbine with a bunch of random parts thrown on. I'm just looking for options to make my 14.5" bbl legal while keeping the "M4 look".

Its not about using what socom uses just because its tacticool. I'd be happy if I can mount a standard A2 on a 14.5", but I can't. So I'm just looking for options. The KAC M4 QD is just one of them. The extended A2 looks funny and I dont really want a 14.7" bbl.

For shame Optics! You're a vendor and you don't have rear sights on your gun!

Thanks for the pics. I see that it hovers at around 31" OAL. Good enough for government work.

HAHA I just took one of the uppers we have for sale and put it on my lower for the picture .

Well unless you are using all Colt parts, then you are still going to have "some carbine with a bunch of random parts thrown on". Would it be more important to you that your rifle resembles milspec more in form or in function?

Not trying to offend you, just trying to help ya save some money. IMO the KAC FH is a total ripoff, the only reason why places can get away with charging so much for it is cuz of the tacticool morons who need absolute 100% milspec and I hate to see someone get ripped off. I saw the ad on ARFcom: "what Tier one units use" lol give me a break!

Honestly though, if you have a 14.7 or a SDI extended, nobody is gonna know your front end isn't milspec "looking" other than you. Functionally it makes no difference, take the extra money you would save and buy something nice like a Colt, Noveske or LMT.

I suppose I'm just post whoring at this point --> YARRR!

But I'll say it anyway.... A 16 inch barrel w/milspec carbine stock meets the 30 inch min OAL.


I'm a fan of the Phantom as well. My next upper will sport a 14.5 inch barrel and a pinned Phantom = 16". Closest I'll ever get to an SBR in Kalifornistan.

Does anyone know if the 14.5" bbl is long enough to be replaced with a different flash hider and maintain it's bbl length?

I intend to move out of CA when I graduate and I'll probably replace the phantom devise with an extended A2 flash hider. Is 14.5 enough bbl for a gunsmith to work with or will I end up with a shorter bbl if I get the flash hider replaced?

16" barrel length is Fed NFA regulations, so unless you can SBR it you will need to maintain the 16".
The 30" OAL is Kaliban, Fed only requires 26", open.

A Sabre Defence Extended A2 FH WILL bring a 14.5" barrel to legal 16" length. I used one in my LMT MRP build.



That's my 14.5" MRP barrel with extended A2.

Is that a 10 rd. P-mag? Is there such a thing?

I don't think we're talking about the same thing.

[J_Rock]

I think what he's trying to say is that the bbl must be at 16" no matter what because its a Fed law not a Kalistan law.

Sort of a hijack here but does the FH have to be permanently attached (i.e. welded) to maintain the 30" CA overall centerfire rifle length requirement? I know to maintain the Federal 16" overall barrel length requirement requires permanent attachment.

Only if you have a 14.5" or 14.7" barrel. You shouldn't have any problems making 30" OAL as long as your barrel length is over 16".

Or you could just save money: get a 16" barrel and reap the benefits of a more reliable gas system and more velocity.

Sorry, gotta call BS here...

The 14.5" barrel with a carbine gas system is more reliable than the 16" barrel with a carbine gas system.
In a 16" barrel, mid-length is the way to go and it's more reliable than both barrel lengths with carbine gas systems.
