Although the M249 was adopted in 1984, it wasn't until the 1990-91 Gulf War that most of us civilians really saw one in action and I was no exception.  I was in college at the time and I soaked up anything and everything I could about the conflict.  And when FN released the M249S, my memories of that stage in my life were the main reason I wanted one.  I was enthralled with the SAW in 1990 and I was just as fascinated when I picked my semiautomatic version up in September of 2016.  And to this day, I really enjoy the hell out of the thing.  

Well, it wasn't long after I brought it home that I got the bright idea of rounding up old parts to dress it up like it would have looked in the Gulf War.  It should be easy, right?  I mean, the 249 changed over time because it was improved upon so nobody would want those old obsolete parts........or so I thought.  Well, to make a long story short, it turns out that the US Government didn't want replaced obsolete parts laying around so, rather than surplus them, it seems that they were mostly destroyed and today, it's easier to find parts for a WWII MP44 than it is a 40 year old light machinegun that's still in use.

When I originally bought the thing, parts were cheap because there were so few in civilian hands.  I was buying spare barrels for as little as $75 but that didn't last long.  As more and more were out there, the demand for spares grew exponentially and prices increased accordingly.  Fortunately, I anticipated this and bought a lot of bits as quickly as I could.  However, I still kick myself for not buying one of the titanium tripods when they hit the market at sub 1K prices.  Oh well.

Anywho, finding spares cheap was easy in 2016.  What I learned was hard was finding early parts.  Still, by networking, they slowly came in, but the most elusive part was an old-style top cover.  Try as I might to find one, they were unobtanium.  But, lady luck finally shined her wonderful warm glow on me and I found one earlier this year, complete and in almost NOS condition.  It had a few wear marks in the finish from storage over the years, but mechanically, it showed almost zero wear.  Even today, I don't have every single part needed to transform my modern 249 into one from 1990 but the parts I'm missing I don't care to own because installing them may mar the modern parts they'd be replacing (e.g. the charging handle) so I'm perfectly fine with what I have.  

So, let's get to some pictures.  If you're not a fan of the SAW, you may not get much out of what follows but, if you are an admirer, you'll probably enjoy this.  So let's get to it.

This first picture shows the rifle with the old school parts installed and the newer parts that came installed when I bought it new sitting in front:

Every single change they implemented without question made the 249 a better weapon but we don't care about that here.  We're more interested in nostalgia.

We'll start with a couple views of the rifle dressed rocking it's 1980's look:



Dig that funky FN stock that heralds all the way back to the FAL Para model!  And that non-folding cary handle that'll catch on everything is the bomb!!  Optics rail??  It's a full-auto machinegun.  Who in the hell needs an optics rail?!?!?!?  Hey!  Which one of you guys is playing that hair band mix tape?  I LIKE it!!

Let's take a brief look at the retro parts, shall we?  We'll start with the top cover:

Compared to a modern one, the rear sight is the same, but it's more forward on the cover because the only optic they originally envisioned was a night vision one and the only way to do that was to attach a proprietary bracket that would allow the use of an AN/PVS4 night vision optic.  In 1991, they redesigned the top cover to include a picatinny rail so that you could mount a daytime optic.  Although various units have been used over time, the original optic installed was the 4x ELCAN M145 shown below:


Here is a closeup of the manufacturer marking on the top cover:

"3S679" denotes FN manufacture for the US military.  There was an even earlier version of this top cover that had a bit that protruded upward to let you know that a belt was inserted but that version has eluded me to date.  They are vanishingly rare and I don't expect to ever find one.

A picture showing how well the paint for the elevation and windage on the rear sight has held up over the years:



Early barrels had no provision for an upper handguard and the carrying handle was fixed.  Later handles would fold so as not to stand up so high so as to catch on things while transporting:


This particular barrel was NOS and has absolutely pristine rifling.  It's also made in Belgium and has the proofs to prove it:


"TW7" means it's a 1 in 7 twist rate:


Early barrels had a different style of flash hider.  The number you see is a part number:


The early barrels also had two gas settings.  One is "Normal" and the other is fouled.  Running the MG on the fouled setting when it wasn't increased the rate of fire and beat the hell out of the gun so later barrel designs removed this feature.  
Gas system set to normal:


And set to fouled:


Among other minot differences, early handguards had a checkered texture on their sides:


Early and later handguards compared:


Both early and later handguards were designed to hold a cleaning kit.  
On the left side, we find two sections of the cleaning rod and a multitool for removing carbon from various parts:


On the right side, we have the top portion of the cleaning rod, a nylon brush, a copper brush, and a jag to hold cleaning patches:



There is more to come, but that'll do for tonight.

I had a love hate relationship with my SAW back in the 90's.  Loved her enought that I didn't give her up when I picked up NCO but sure hated carrying and cleaning her.

Nice pics and thanks for the trip down memory lane.

Pretty cool.  I did a similar thing with one of my M249's - though I stopped short of the top cover; wasn't sure I cared enough to try to get one or mess with swapping it especially since it couldn't ever be a 1:1 because of the magazine feed system that is part of the gun itself.  Picked up the other Minimi parts though:



I also got pretty much all the other M249 parts you could get (SAVIT stock not pictured, but I have one):




Stock FN M249S:



My other one - technically a MK46 Mod2 - this one could arguably get closer to the original Minimi because it doesn't have the mag feed system:

Very cool OP! That is exactly how the SAW I carried as a USMC 0311 in the early 1990s was setup. Only thing that I don’t remember was the early hand guard - I think ours already had the later style. But we did have the tulip flash hider, fixed handle on the barrel and the original stock. The plastic stock and heat shield for the barrel arrived some time later and I remember the old tulip flash hider barrels did not have the extended pins that the front of the heat shield hooked onto - so it was kind of a crappy fit. That heat shield for the barrel always struck me as stupid since the original plastic hand guards on the SAW do a pretty good job of protecting your hands. Brings back memories!

A lot of guys in the early 90s hated the SAW but I loved it.  If it wasn't beat to shit you could deliver some serious hate with that thing, considering how lightweight it was compared to the more general purpose machine guns.

Funny story - when I went to join the Marines I told the recruiter I wanted to be a machine gunner because I wanted to carry and shoot the SAW. He must have been a grunt because he told me that it was the regular 0311s who carried the SAW so that is what I did. When I got in and trained with and carried them I realized that they are OK but certainly not the incredible weapon that I had read about prior to joining up. Every one I got to use was clapped out and required work and luck just to keep running. The most reliable gun I ran into in the service was the M16A2. That was back in the era when it was all the rage to bash the M16 too! I realized later that almost all of the books on modern military weapons that I loved as a teenager came from England and they really don’t know shit about small arms! Every one of those books parroted the same shit about how the M16 series of rifles were unreliable and required kid gloves etc. while the super modern L85 was more accurate, more reliable blah blah blah. Turns out it was all wrong LOL!

Alrighty.  My continuation of this little essay has been longer coming than I intended but Life has this nasty habit of throwing you a curveball sometimes and you just have to adapt.  BUT, I've got some time this evening so let's pick up where we left off.  We'll do that by taking a quick look at the inside of the top cover:

As far as I can tell, nearly every single part will interchange between this cover and a new style cover.  The only real difference is the bare aluminum feed track.  It'll still interchange I think but the later cover feed track has a series of holes drilled along its entire length to save a little weight.  


And now, let's take a quick look at the early stock:







The majority of this part is an aluminum alloy so it's fairly light weight.  The shoulder rest is spring steel and the webbing between the upper and lower stock tubes is plastic.  When the stock is being assembled, the upper aluminum stock tube passes through a plastic sleeve molded as part of the webbing so that you don't burn your cheek in hot weather or freeze it to the stock in cold weather.  The lower stock tube is just exposed anodized aluminum.  

Early stocks had no buffer built into them.  The buffer was placed on the recoil rod assembly in the form of a bright yellow painted spring:


Part of the 1991 Product Improvement Program (PIP) was integrating the buffer system into the stock and making it hydraulic instead of a spring.  Here are the early and later stock/recoil rod assemblies compared (early stock shown is missing the plastic webbing):


This means that you cannot change out stocks without also changing out the recoil spring rod.  I've heard it said that you can't use the early system on the M249S but, when I install my early parts, the rifle cocks and dry fires just fine.  I have not live fired it though so I cannot say with 100% certainty that it'll work but I don't see any reason why it wouldn't.

Here, we see the newer stock at the top with its built in hydraulic buffer and the early stock at bottom with no buffer:


A bit of minutia.  In the September of 1983 Operator's Manual, it clearly shows the recoil spring guide rod being used as a disassembly tool in a variety of places but, by July of 1991, this has been replaced by using a section of cleaning rod.  Interestingly, the April of 1984 Technical Manual specifically talks about what to do to reshape the tip of the guide rod if it has been broken off.  I have two early guide rods, one with the tip still intact and another that was refurbished for continued use after the tip broke off:

I guess they eventually decided to stop using the guide rod as a disassembly tool because the tip was too fragile.  Consequently, the newer rods have no such tip and there use as anything other than a guide rod was discontinued.

Very nice of both of you gentlemen to share those pics.  Very nice gats.

Didn't the Minimi originally from FN have the STANAG magwell?

Now, we will look at some early parts that I have but have not installed and one that I have never bought and probably never will.

First up are the stock retaining pins:

On both early and later 249's, the pins are captive.  In the picture above, the early pins are in the white and shown laying on top of the pins that replaced them.  While it's an easy enough procedure to swap them out, I find it pointless to do so because the newer versions are far easier to manipulate.  With the early versions, the upper one is removable by hand and the lower requires the use of a punch.  The newer versons, both upper and lower are manipulated without the use of a punch and easier in both cases.  


Next is the pistol grip:

They are identical other than the texture.  The early grip is smooth and shiny relying on the molded grooves to supply needed grip.  On the later style, the entire grip has a stippled finish to provide maximum grip.  It also has a part number and manufacturer number that is lacking on the earlier grip.  Both have a trap door at the bottom to allow the storage of a lubricant bottle and a few bore patches.


Here's another view of the early grip in a different light showing how smooth the general finish is:

This particular one is pretty beat up so I'm still looking for one in better condition.

Both early and later grips are molded internally to fit a lubricant bottle so that it won't rattle around:





The extra space is intended to fit a few bore swabs.  I LOVE this kind of efficiency!


The last thing I'd like to discuss is the charging handle:

The one that comes on the current M249S is the latest version.  It's "skeletonized".  That means it's been lightened by removing as much material as possible to save weight.  Early versions were the same shape but the 12, 3, 6, and 9 o'clock positions were solid steel.  The early version of this part is currently selling for around $275 and requires a pin punch and a hammer to replace.  To replace this part is more intrusive than I care to be and, added with the cost, makes purchasing this part pointless to me.  So, I have forgone it.  


So that's it for now.  Over time, I have pulled together a small treasure trove of parts and printed material regarding the M249.  Eventually, I will probably put everything together in one post but this will do for now.  If you have anything to share, especially personal stories about your time in service with the MG, I'd love to hear it and I'm sure others will as well, so please share your experiences.  Thank you for your time and I'll see you soon with my next musing.  May God bless you, each and every one!

Looks like FN applied for the patent on the magwell in 1977.

That aligns with the US Army requests.  Normally, not a place I'd reference, but the wikipedia article for the M249 seems to have a pretty good timeline for the Minimi and M249:  https://en.wikipedia.org/wiki/M249_Squad_Automatic_Weapon

While Wikipedia has skewed left in recent years, there's a whole lot of technical data on there that is properly referenced.  Where do you think I got the link to the 1977 patent?

Early 80's SAW gunner here.  Great post, and super cool.

I remember one of the issues we had was with the barrel latch... the sling would snag on it, and when you grabbed the carry handle during IMT, the barrel would come out, and the gun would stay behind.  I don't remember exactly what the barrel latch looked like, but I think it's higher profile than the current setup.

I never experienced any firearm more uncomfortable to carry than this thing, to include the M60.  Parts sticking out in all directions, carry handle being the worst!

Crazy high rate of fire, loud green box to the belt.  Idk, I never liked it.  

But well done, great job putting that together, looks pretty damn cool, and lots of memories.

Man, this is a cool thread!  I first got to the FMF the old saw was on the way out. I was a 0331, so I spent more time with M60E3, but I remember the old SAW.

One thing I remember was the tombstones changing from green to black and the nut sacks were frog pattern.

And I agree with the poster above, the 60 was heavy, but the saw had no comfortable way to hump it!  It was fun to shoot though!  The high rate of fire was scarry as hell when fired from inside a building, it was horrific!

OP, where do you find your parts?  I am looking for old handguard for my 2nd 249s. I'm going to set it up as a Minimi Para
