My M203 barrel just arrived and it appears that my FNMI 20" USGI barrel use to be a host to an M203 due to the wear marks left on the barrel where one would've mounted.

Mine also came in today. I took the orange paint off using rubbing alcohol. The tab covering the Colt logo was a pain in the ass to get off. It broke and crumbled and left an edge I couldn't get. I got out a heat gun and heated it just a little and got it off.

The M203 is heavy and just feels well made. I can't wait to mount it to a rifle. Now I just need to get my rifle barrels. The M203, 629, 603, 604, 604 and 723 or 733 is how I will build them.

I will get some pics of everything soon.

I wish I was rich. I am a poor boy trying to live the American dream! I have just been buying parts here and there when I have the extra cash. my next parts buy will be a couple of months down the road. It is the last of the parts!

The M203 is really nicely made. It is heavy and gives that feel of nothing being airsoft. It is going to be a fun rifle to have and an unusual one too. I'm tempted to sell my C7 upper and get a slick side.

Strange how some have no Orange ring/paint and Colt cover and some ( like mine ) had nothing  and were ordered and shipped roughly the same time frame ?

I think the orange muzzle and hiding the Colt's logo are only required for shipping into the US.

Maybe there's a new guy in the shipping department in Hong Kong.

I wish the FNG would have went a bit light on the glue and orange paint. I have to get down inside the barrel. I am happy with this M203. It is nice and well built and it was better than what I expected it to be. It will be a fun gun to take out and shoot. I have some plans for the gas grenades.

Mine was supposed to have the Orange ring but din't have one.  The Colt's symbol was covered over, but easily removed as was the  adhesive.

Now that is just awesome! Looks good. How does it feel on the end of the rifle? Does it make it feel heavy and unbalanced?

Looks great.  As far as weight & balance, I was surprised at how good it felt.  I get to fire my 603 build tomorrow that mine is on.

Very balanced feel. Not heavy or awkward at all, Not surprising as it replicates the original 203.

I have a question on what the rounds looked like for these in the VN period?  I'm having a difficult time finding anything and when I do I don't know if I'm looking at new or vintage rounds.



Thanks

If the heads of the mounting screws are cross drilled you guys should safety wire them in place.

Also need to get some side sling adapters on these.

The gold are HE the green shells with black caps are buckshot


Below, the green or bronze-ish shells with the long white caps are parachute flares








HE and CS




The long shells are various colored flares, left side third row down are various colored smoke, bottom left CS, bottom middle HE,  bottom right buckshot



Shell colors varied widely, gold tint, bronze tint, green, (I think I've even seen some that were sort of silver).

44Echo10, is that you carrying the M203? The one picture shows a guy (I'm guessing you) holding the M203. The latch that  you push in and open M203 looks to be worn. Was it that worn? If so, was the finish very thin on it?

Also, why so many different color flares? What did they do at night?

Great photos and thanks for sharing.

LOL. No, not me. I'm a bit younger and Ordnance Corps not a Grunt, God bless them, somebody has to do there job, I'm good at fixing things. Uncle let me play with one or two of his 203's back in the 1990's. Photos borrowed from the net for reference purposes.

Parachute flares provide illumination, the bigger ones will seriously light some shit up. Colored flares are usually clusters and would designate certain commands depending on SOP.

My 3rd year,1989, into the USMC they made us do the USMC Rifle Qual with our M16A2 with attached M203.  The years before grenadiers had always been issued an M16A2 for Qual week.  I had always shot expert the 2 years prior.  With the 203 I missed expert by 4 points.  It was due to the M203 left to right balance mainly especially in the off hand at 200m.  Most of the firing using the hasty sling with a tight position the balance did not effect it as much.  The next 2 years I was issued an M16A2 again and qualified expert giving me a 4th award.  Not to brag or anything.

That round is one of the high pressure/high velocity 40x53mm belted rounds used in the Mk19 automatic grenade launchers. It wouldn't even chamber in an M203 and if it could, it would blow up the launcher because of the aluminum barrel. It's my understanding that the HV rounds will chamber and fire from the M79, being that it has a steel barrel, but you have a good chance of dislocating your shoulder if you do so. I have seen a low velocity prototype flechette for the M203/M79, but it used a unique sabot that held each flechette dart individually, it only had 9 or so darts. It wasn't effective as the velocity was too slow to stabilize the flechettes, hence the reason that they just stayed with the M576 buckshot type rounds.

Oh frak! You're right.  Happened to think about this round and did a quick search and that was the only flechette pic I came across. Found the same pic and description for MK19 on a different site tonight.

Oh yeah, MK19 hv 40 mm round would seriously ruin your day if fired in a 203.

Need to file down the barrel retaining/locking latch in the reciever, damn thing hits my bayonet lug. Gonna need to take off 3/16".
Also, the barrel band is loose. even with the insert. Would a actual milspec assy. work?
It's going on a 723 clone with a M4 profile barrel.
I'll try to get the latch filed tonight for some pics

Whatever they used to glue the little shim to cover the Colt's logo left hard residue on mine.  Grabbed the closest tool on my bench which was a copper toothbrush and found out the finish is not very hardy. If anyone wants to knock the newness off the launcher could do the same.

Gonna hit it with some matte gray spray. When I was in the Army the standard practice in the company arms room was to cover any surfaces that were missing their factory finish with gray solid film lubricant spray, so a lot of the weapons had a patchy appearance.
