Photo review of the HobbyFix Colt M4A1 Carbine

Stunning M4. Just an idea, could you not use an airsoft one piece outer barrel for yours? But will shut up if your going for originality.

Only if one of my M16 variant can get the same treatment of your M4 ...

I finally found the time to finish my project. It was a long way to go, and it was full of ups and downs. I had a lot of setbacks, but every single meant more encouragement. Looking back, I am glad I did not know what would come along with it, as I would not have had the guts to start it.

It all started that I didn’t like the selector switch, which did not engage in the SEMI position. I don’t know why HF didn’t make it right, as they should have been able too. I tried to rework it or to fit a real one. And there was that moment I didn’t pay attention and scratched the finish. Trying to repair it made it worse, so I had the idea doing modifications and a refinish in black. At one point I broke a lug that holds the trigger guard, and that was the saddest moment in my whole career as a modelgun enthusiast.

I have to admit I would not have been able to get the modelgun from japan and do all the modifications and repairs by myself. I had a lot of help, and I would like to thank everyone who contributed. I really hope I did not miss someone:

8ace for his skills and patience. He simply did not accept a “not possible”. He has that rare “no task too difficult, no damage beyond repair” mentality. This is your work, my friend!

Shazhib and HIGUsan for their help getting this modelgun and information about it from Japan. Thank you, my friends!

Cerwyn for all his encouragement, always open ears, understanding and help. He had to drag me along more than once.

ljerr2 for his great help getting me spare parts from the USA. I can not thank you enough.

Sadly I can’t take good pictures right now, the dark and snowy weather requires a flash, and that ruins the pics. I will do that asap.

I have written a lot about the modifications. The most important ones are:

Fitting a real (modified) selector switch, that clicks into the SEMI position well.

Modifying the barrel to a realistic “HB heavy barrel” profile.

Reducing the front lip on the receiver, drilling a drain hole, and removing traces from casting.

Adding real parts like a receiver extension (buffer/stock) tube, carry handle, charging handle, hand guards, stocks, front sling swivel and trigger guard.
All parts came from COLT and are mil spec. I could leave them in their original color, which fits the refinished receiver parts well, so I knew I was not too wrong about the color.
HF had chosen a dark grey, which is right for early M4A1 carbines. But I would not have been able to get the exact color, as well as real early spare parts in grey, so I can live ith the black color, even more as current Colt rifles are black.
I managed to obtain both types of Colt stocks, the early “CAR-15” style one that is flat on the back, and the later slanted type that was introduced around 2002/2003. I can’t make up my mind which one I like more.

Don’t get me wrong, the parts HF used are great too, and you can hardly, if at all, tell a difference. Anyway the stock and tube had the commercial dimension which Colt does not use, so I wanted the right ones.
I also gathered some good accessories, a blank adaptor (the ones for the M4 gas system are yellow, the ones for the M16 are red), a nice selection of magazines, a military issue sling and so on.















You can't see the biggest and most difficult modification/repair. 8Ace replaced the section with the broken trigger guard lug by a custom made aluminum part. What a masterpiece!

Here are some detail pics. The sun was quite bright. It is hard to find the right lighting but you can see the details quite well.

Please note the "Heavy Barrel" barrel profile (custom made steel and aluminum barrel part by 8Ace - rock solid now, and heavy), the real front sling swivel (Colt Govt. issue), real carry handle (colour does not fit perfectly, but color varies on real rifles as well due to anodizing), Colt stock (N1 marked), Colt buffer tube, mil spec fire selector (clicks very positive into the SEMI position), reduced front lip at magazine well (made by 8Ace), Gun Kote finish (applied by myself using an Airbrush).

I also have the newer Colt stock, a real sling, real Colt hand guards, real Colt and Govt. issue magazines, a bright orange plastic magazine for blank ammo and a yellow M4 BFA (blank firing adapter).

It's been three years now working on this project but I am finally satisfied. what do you think?

Please note: You can't see the most difficult modification/repair 8Ace did, replacing the broken trigger guard lug by a custom made aluminum part. What a masterpiece!

I was able to take a few extra photos. And I was also able to compare it to an unmodified HF M4A1 from the same series (first production run).

Note the dark grey colour of the unmodified HF version. HF was right with this colour as real Colt M4A1s from that time were mostly dark grey.
I did a refinish in flat black. The colour matches current Colt production runs as I could use a charging handle and carry handle without refinishing them. The colour fits quite well.

I am really happy with the modifications as we could make this great model even more realistic.
If only HF could see this. I really love their original product, but I am proud I was able to improve it even further.
Hell, this project really made me the king of the nitpickers ...

You are a king now, at least for modelguns ;-)

Modellers who put together plastic ships/tanks/airplanes spend a lot of time getting their kits adjusted from original-in-the-box to original-military state by doing a LOT of modifications and improvements. This is not considered nitpicking, and I think the same could apply to the modelguns in a quest for the perfect one (visually).

Even if it's "just" details, it was a tremendous amount of work, and I'm sure it wasn't easy for all involved, despite appearances.

Well done!

Most important is that is made you happier :-)

PS: yeah, they both look the same for me! ;-) (duck&run)

Thank you! No need to run. I can understand that they look the same, but comparing the pics you should see the modifications ...  

This project took a long time and was expensive. And we had a few setbacks. In my darkest hours I sometimes feared I would do something that would ruin my M4. But seeing the miracle work 8ace had done, I had no such fears.

Is the BFA just for looks or has it been modified to fire blanks?

It is just for looks. German gun laws prevent a modification to fire blanks strictly. It is a dummy only model, with blocked barrel and no firing pin. For legal reasions I kept the original HF design which complies to strict Japanese laws.

Wait! Forgot to put on glasses! ;-)

First photos updated with Servimg

After 10 years I am still fascinated about the HobbyFix M4A1.

It is not easy to get information about this model, but it is confirmed that there were two production runs.

Here are photos of serial # ...244. I found them on the internet. I am quite sure the 2xx serial numbers were used in the second production run, whereas the oxx - 1xx were used in the first. Note the slightly darker carry handle marked "A2". This one also came with the M16A4. I am quite sure HF used real surplus parts on this, whereas the dark grey, "AH" marked could have been made by HF itself.



Note the drain hole that was missing on the first production run.

Here are some impressons of a first production run model showing some traces of wear and handling.

If you ask people who have handled a real one they say it looks and feels very realistic ...

Finish looks close to the real M4 made around 2000. Markings are on the spot, only drawback is that they are engraved, while the real ones are roll-marked.

Lest we forget that you can get a good semi-auto AR-15 rifle for half the money you normally have to spend for the HF model ...

HobbyFix M4 in the snow impressions ...

Original HF M4A1 (first production run) with DPMS magazine (dark grey finish) that came with the model. In the sun the finish almost has a shade of purple that can be seen on some real Colt M4/M16 rifles made in the 2000s.







For comparison, a real "purple" Colt M4 upper:

I think it looks great in the natural light ...

Better than the real thing

I stumbled upon this thread on the AR15.com forum where guys are discussing about real AR-15s.

Well, one complained that he bought a carry handle a year ago and found out now it was from a "HobbyFix", thus being a fraud.

Finally one explains that a HobbyFix is a "toy", showing a picture I have posted long ago on the internet. As the thread is closed I can not reply and putting it clear, but I am sure the guy got a real carry handle from the mid 1990s, and not a HobbyFix.

Still sitting here shaking my head in disbelief.

So if you have some free time and would like to see how enthusiasts are discussing on other forums take a look here:

Meanwhile I am cleaning my HobbyFix gun toy.

This is a Japanese Blog entry where the author is explaining how he fit a real fire selector to cure the problem of the HF selector not clicking into the SEMI position.

8ace has done it similar to mine but I find the step by step explanation really helpful.

In January I was able to post pictures in light snow. Right now just before Christmas I took it out for some playing in the rain ...

Note the 20 round magazine.

Its looking good madmike

A quick check on a sunny day in January ...

As usual mate, I'm in awe
Fantastic model.
