where can you get a non NFA looking 607 mod these days. I emailed Pat who used to make them but have not heard from him.

just to clarify, you are wanting a faux 607 moderator.......3.5 inch model?

I'm not wanting to derail this thread but I was wondering if a rifle like the one pictured runs reliably with the 10" barrel?  Were any modifications to the gas port necessary?  What weight buffer is it running?  Thanks.

Let me just say I have something a little 'different' planned for my 605. I'll never outdo that 'Penthouse' shot though.

I use an H1 buffer in my 10" barrels... Whatever size port hole is in a JTdoublestar 10.5 inch barrel.

IMO a JT A1 profile barrel with the FSB smoothed over, reparked and modded for taper pins is a very good clone.

the rifle pictured is running ~15" of barrel (with a pinned on FH for an OAL of 16") and the gas port has been opened up a bit to get reliable functioning, It's running a standard rifle buffer

here's a pic of what a 605 looks like in case you are unfamiliar with them

do you need a true 3.5" moderator, or could you just cut down a 4.3 moderator such as the one made by Brick to get what you need?

I went with .093 on my 10" barrel, an H2 Buffer and McFarland gas ring, Wolf extra strength extractor spring and D ring seal. Runs great so far.

Ali,

Found it, sent a PM with details.

There is a psuedo crush washer machined into it, I can't remember who made it or where I got it, but it was one of the guys here on the forum.

I just have to decide on my plans for NFA items Corp or individual

 I would like to see them conical on the inside like the XM177 moderators personally - but maybe a shallower cut considering the length? It might not be accurate historical -wise but they'd be lighter and it would give them some flash hiding capability. Just an idea.

Hi Morg been awhile........

Anyone here have the FLAMING PIG? Dont have one, but how is that cut on the inside? From my understanding it reduces flash among other things. Maybe the 607moderator inside could be machined be similar to the pig???? Just a thought.....

that would get expensive...probably cheaper to buy a pig and lengthen it, if you really need it to be 3.5"s instead of the standard pig length

pig dimensions:
7.2 ounces
1.35 inch Dia
3.28 inch OAL

funny how old is new and new is old......hummm

it would not be to hard to macnine that radius on the inside of a 607 mog
Why would you want to remove it? Just eliminate the removable option that you show in the pig amd that would keep cost down

A. I think it would look better at the muzzle end

B. It should reduce flash at least a little bit, similiar to the 'trumpet' cone - style flashhiders commented on in a recent thread. Can't see that the current 607 moderator does anything except add weight and look cool.  Just an idea. IIRC the originals would not have looked like this, because there wouldn't have been room for any baffles, but I'm being practical here. IIRC b_rogers, didn't you  build a moderator using tubing, which I would bet is pretty effective flash - wise, but would likely ring like a Vortex. I'm thinking something between the two would be nice. Again, not being historically accurate as much as practical.

If someone is making the Faux 607 Mod with the pig insides, I would be up for buying one or two.....or three.

Best of both worlds.... It would have the 607 looks and also help keep the short barrel gas pressure up for an increase in reliability.  (Kinda like the Krinks use...)

FWIW, there does not seem to be any evidence that the KX3 does anything to increase back pressure, and all such verbiage is long gone from Noveske advertising as well.  

I would suspect that anything designed today that was muzzle-mount and had the ability to capture and direct enough gas to appreciably add back pressure would probably end up being classified as a suppressor - much like the original moderators themselves.  

The KX3 is nothing more than a big, heavy, overtly complex conical flash hider.  

That being said - I would have to agree that faux-3.5" moderators without baffles are little more than barrel extensions, while 4.5" models at least have the conical portion and flash suppression slots.  I reckon if you were going to go with a faux 3.5" moderator, you may as well get it function like a conical flash hider.

FWIW.  If you have ever worked with and around SBR's in close quarters the KX3 dramatically reduces the sound level to the sides and rear of the rifle.  To the side and slightly in front of a KX3 is deafening.

Vs a original. I ordered one from 45 bravo a year ago ,,,, still waiting,,,,,,waiting,,,,,
So a asked braceman to make one. I took the outside diameter
From my xm style moderator ( 45 bravo) and I guessed at the length .

FWIW that one braceman made for Trimdad looks just about like what I was talking about. I would love a moderator like that. For what, I don't know. I'm about done buying parts just so I can sell them off when I'm not working. I hate to say this, but I'm about done with this 'hobby'. Three times now I've gotten within a whisker of having several builds done, and three times I've had to sell off my builds. It's past frustrating frankly. I would do better by putting the money into other things.

You got me beat, Morg. Only a couple life reversals since BRD started for me.  

Speaking of 607s, my 607 project is lacking just an SBRed barrel. And the paperwork I should mention. Not sure that will ever happen now...

Well I can make them however you wish, but the real ones I have seen are just as they are shown on this page. They have a .250 deep x .375Dia  counterbore on the muzzle end. These are aproximate measurements and should not be taken as correct measurements to make a moderator, I am not an engineer or  lawyer and did not stay at a holiday in express last night :)  All kidding aside, I don't have my drawings handy but that the way the real deal is made, I can make them however you like though.

I too would like to purchase a faux 607 moderator (visual only, not functional).  As has been mentioned, the weight of these is an issue.  Pigs though, do help greatly with the sound and concussion levels from the operators perspective on 10-10.5" barrels.  I've not shot one of the originals, so I can't speak to how they compare.  Also cannot speak to the backpressure issue.  Trimdads version looks slightly different from the real deals I've seen pictures of.  The neck at the wrench flats looks longer than the images I've seen.

 This thread among several others shows pictures of the real deal:     http://www.ar15.com/mobile/topic.html?b=3&f=123&t=296919&page=2.

It would great if someone here would tool up and make some of these.  I would vote for original exterior dimentions and would lean towards the conical design because of the possible affect and weight savings; but like the visual of the original small opening.
