As the title states, I wanna see some VERY early 604s. I am interested in building one, if I ever get the right parts & am curious what features you used, or what is correct. Plus, as we all do, I just like to look at other people's Retro builds. So post those VERY early 604's if you have them!

None of the 68 people that have viewed this have built a very early 604?
Link Posted: 10/31/2009 3:46:58 AM EST
I nearly did.

Well I didn't build it...

This is the best I can do to date, shooting for a very early 604, but have considered using the walnut furniture for this one???? I have the pictured set of 'shinney' furniture and assume it to be correct for a early 604. comments if you got 'em.

My first exposure to retro BRD:


Examining my first sampling of US Anodizing's work:


All put together:








It didn't begin as a retro. I just wanted a 20" rifle and it turned out this way. That is though how it happens to have some non retro guts: the barrel's a CMMG 1:7 A1 profile, the trigger's an LMT two stage, the bolt carrier's a Young slickside and the bolt is a BCM. While I got the dimpled selector from Heatnbeat, I somehow decided I didn't need any other dimpled parts.

Here's the real deal with waffle mag goodness!

Here's mine; came to me as a barreled upper. Although the upper isn't the earliest with the cut behind the ejection port, it is a straight forge, and from what I can tell, has the original M VP barrel. It also has original dimpled pins and a "Many Circles" mag button and no-drain handguards. I'd like to eventually put a dimpled mag catch and selector and a transitional bolt catch on it, but I need to find the mag catch and selector for my 601 first (I want originals, not repros).

OK guys, just got back from a weekend trip, & I gotta say the pics look great.

Looks I like a have a correct barrel (M & VP marked between the FSB legs right?), gas tube, shiny no drain hole HGs, & a very nice Type D. Just need to get a few key pieces (already in progress), & some lower receiver parts from heatnbeat.

Thanks guys.

Yeah pretty much, but I was not exactly sure on the barrel, whether it was correct or not.

I don't think I am going to go 100% correct on this one though, which is what I've said about other builds too. I plan on using a modern buffer tube & buffer, unless I find a killer deal on either or.

Oh yeah, I have a chrome BCG to, to ad to my list of parts on hand.

Yes,M vp is gtg for very early forge.

On the bottom is my old 604 clone. I sold that upper and replaced it with a grey one. The one pictured is a NDS XM lower on a Colt 604 upper. The barrel is an original M VP and the BCG is a 601 chrome assembly.


I am too tired to get the camera out and take a new pic right now.

Since your rifle is a factory built gun, I wanna ask is the receiver colors like the XM gray NDS uses, or a brownish color like a 601? It looks pretty gray in one picture & kinda brownish in the other. Could be the lighting though.

Just want to know so when I go to order a lower, whether to order it in the white or already finished.

Thanks.

Hmm..., looks like I need a few more dimples.
Link Posted: 11/2/2009 8:19:42 AM EST
I have everything except a correct buffer and a correct very early upper.
Link Posted: 11/2/2009 8:58:39 AM EST
The 604 clone while not correct was my first attempt at a 604 build. The upper is an early 604 with recessed lug, shiney HGs, but the upper doesn't line up at rear of ejection port and the barrel is marked MP 12.



I have all the pieces for a proper 604 build minus an early receiver ext, rear takedown pin with diviot, and a M vp marked barrel.



My SP1 barrel is marked M VP but I wont use that one





Link Posted: 11/2/2009 11:59:17 AM EST
Here's my attempt at an "early" 604. (It's not a "very early" 604 since the bottom edge of the ejection port does not line up with the top of the lower receiver.)



Link Posted: 11/2/2009 12:48:29 PM EST
My build from the days before NDS was around and I had to modify an A2 receiver,


Need to divot my selector


Not an early enought upper but it works


Early BCG and Buffer

This is my attempt at an "early" 604.













Still looking for some parts to finish her up.

Wow,alot of very nice 604's here..But to be honest,I would trade my "very early square forge" 604 upper for a 602 upper in a heartbeat! Nothing against the 604 or the airforce,But when I do living history displays,I do an army setup..
Link Posted: 11/2/2009 2:43:14 PM EST
What is the difference between the 602 and early square forge 604?

Basically, The arrow and R on the carry handle of the 604 is raised, and the 602 is engraved. The area above the charging handle may or may not be round or angle cut too.

I just took a look It is a tough call. I would say the XM gray would be closest. The upper has a just hint of brown. The lower seems just a hair darker then XM gray.

I would too. When I first got bitten by the "retro bug," I quickly decided that the 602 was what I wanted. But after reading about how difficult they are to build correctly, I decided to go with a 604 instead.

Nice one TGus! Is that a reweld? Or did one drop off the retro amnesty truck 41 years back? Somedays I really wish I could own a machine gun outright.

Thanks. That one was brought home from Vietnam by an officer and registered in the 68 amnesty.
