Initial Impressions of the TM SOPMOD M4 AEG

Recommended Posts

It sounds better than an AEG. Less sewing machine-like.

 

For the gas gun types out there, I don't have raw force or displacement numbers, but based on feel, the SOPMOD, compared to a heavily upgraded SPM16 or Escort 416, has about 30-40% of the recoil.

 

I'd like to borrow a compression force gauge from work to see if I could get a comparison measurement, but we'll see.

Well, i want to change the outer barrel to a CQBr one, is possible if i change the delta ring and the outer barrel for one for normal AEG?

 

Not right now. Different upper receiver/outer barrel. Although a shop in Shinjuku, Tokyo (Air-borne) offers to shorten and re-thread the stock outer barrel for a fee. I believe First -JP in Osaka offers a similar service.

Wasnt there a thread link in here that stated that the upper receiver would accept a G&P delta ring?

 

If so that means that you would be able to at least switch rail systems provided you still retain the stock outer barrel.

 

Can you confirm that Anakchan?

By guestimation, how does the recoil compare to your real AR? ^

Like....not. :)

 

A real AR isn't much recoil at all, but the TM isn't close to even that. The heavily upgraded SP or Escort 416 is much closer to real AR.

Couple more questions as my packages are on the way and i cant wait to receive these things!

 

1. How is the FSB held on? Pins and a set screw on the bottom? If it is pinned, is it pinned the right way, ie cutouts on the barrel for the pins to index into? I cant stand wobbly fsb's.

 

2. Are real steel endplate sling adapters able to be used on this thing or do we have to make a relief cutout to accommodate the wiring?

 

Thanks guys!

Pins only. Stock TM ones seems to hold quite well and is not wobbly. The lower/upper RIS are held by the front cover plate (sorry, dunno what that's called since it's not really a gas block), which in turn, is held by the FSB.

Good Q. I have the same concern as you and haven't tried 3rd party endplate slings. I'm particularly keen on Magpul's RS ambi swing swivel (which can swing under to the left or right!).

Im thinking real steel plates will probably work but yeah, im 99% sure we are going to have to make a relief cut to accomodate those wires.

 

Real steel sling endplates are generally REALLY tough so they might require a little more than a dremel. Not necessarily a bad thing.

Or just make things easier by using the adapters that bolt on over the buffer tube/castle nut, like the GG&G Agency series.

I don't have a real endplate to try out, but think it'll work fine. There is already a small relief in the TM one, so it looks like the small protrusion on the real one would need to be cut and you'd have a nice slot there similar to the TM one:

My only gripe is that generally, the over the buffer tube style sling plates tend to mess with the first positon on the stock tube when the stock is collapsed.

 

We will see when i get my units. :)

Anakchan, can you confirm that it uses regular M4 inner barrels, not some different C-clip slot position like the TM M14 inner barrel?

 

Regular inner barrel...I've switched to a PDI 6.01....(375mm)

Anakchan,

how's the performance on the .01's in your m4 so far? max distance/groups/etc. compared to stock. from what you can see?

just curious, I swapped out my .05 for a TK 363mm. gonna try it out this weekend, see what difference it makes -if any.

 

curious to see what parts combinations and performance others are getting from their own different set-ups.

 

thanks!

Ah I remember you asking me to do some tests before, unfortuantely I've not been out to skirmish with it yet, nor taken to any of the (really short 12m) ranges in Tokyo. I have a feeling that you'll get to test that before me. Sorry 'bout that GF808.

Does anyone see a reason the M4 cannot be rewired to the front or to take a different battery pack? I would assume its possible, just wanted to double check with you current owners

Yes it can be rewired to the front. In fact TM's upcoming M4 Carbine (March '09) will be wired to the front. When TM designed the Sopmod, I think they already catered for the Carbine in mind so there's a cut/groove in the upper receiver on the front left for wires to go to the front. I can squeeze in about 4 wires there at the moment for Gandolf's SW-LONG AB-FET (2xwires for trigger, 2x wires for motor). Unfortunately that FET's too big to fit into the RIS :-(. May need to see if Psyphyer's FET will fit in there instead.

 

But back on topic, yes it can be wired to the front. Have a look at the last photo of this link, FirstJP in Osaka has already done it (using PEQ) :-

Are you a midget?

 

:P

 

Gandolf's SW-AB-Long

Surprised you can't get it in there. I have the Evolution stuffed into a buffer tube, it doesn't seem that big to where it could not fit in the RIS.

http://extreme-fire.com/FeatureChart1.html -> the Computer is a touch smaller.

Or perhaps go to a different RIS like a RAS2, SIR, or CASV?

I prefer to be called umpaloompa!!

 

No really, im 6'0 and i shoot nose to charging handle. My stocks are either always collapsed and tucked very close or retracted one position.

 

That link didnt work Anakchan, what is this you say about a marui sopmod carbine?

I go 1 to 2 out. Fully-collapsed is too tight for me. I hear ya though on it not fully-collapsing though.

 

The link he put was the one going around that showed a SOPMOD wired to the front to a PEQ2 unit. Not sure why it isn't loading....worked the other day.

Link is working now. I thought it was going to be a link to the marui carbine that he mentioned.

 

Do we have any more details on this? I havent heard anything about it in the popular news circles.

 

Im assuming its an SBR sopmod?

 

Also, anyone have any idea if active breaking would have a negative effect on the recoil mechanism? How about the motor soft start that the extreme fire fets have?

Anakchan,

ah, don't worry about it :)

I'm kinda wondering how far the float will carry with that TK myself.

btw, what are the other guys in your group setting their sopmods up with? -curious, didn't see anything in TKO yet..

 

Umpaloompa, :P

I haven't tried a fet in it -yet.

I don't think it should have too detrimental an effect, if anything, it would probably simulate the almost-lock-up when you fire semi too fast.

although that is rather irritating a situation.

Ah sorry, no...the link to show that someone else (FirstJP) had put on a different stock to the Sopmod and rewired to a front mounted battery (PEQ).

 

Unfortunately I don't have any pics or information about the TM Carbine blowback. I got that piece of info from Air-Borne, Shinjuku. What's SBR sopmod?

 

As for the AB-FET, I can't imagine it causing anything bad to the recoil mechanism. The only link between the mechbox & the blowback mechanism is via piston head pushing the blowback brass rod when it's pulled back by the gears/motor. In fact AB won't even reduce stress on the mechbox & spring, but it'll relieve stress on the blowback spring even. Dunno about the soft motor starts, I don't have the more sophisticated FETs Gandolf has.

Actually good question! I have no idea what my other members are doing to their Sopmod :D. I think we're all waiting for accessories to come out for it. I'm heading to Hong Kong next week (to sort out my AEGs I left there last year :-( - yeah, still customs issues, like I'm sort of "illegal toy arms smuggler :P"). I'll see if that G&P Defender is out, if so I may pick it up for my Sopmod. Considering doing what that FirstJP has done.

Thanks for the info guys.

 

I suppose we really wont know how the system reacts to fets until one of us gathers up the necessary testosterone and installs the damn thing.

 

Also, in regards to the SBR carbine, i meant short barreled rifle. I kind of assumed that TMs next release would be a 10.5 inch SBR sopmod blowback thingy of doom!

 

Chan, if my sopmods get here before you head back to HK ill go ahead and install an ACM DD RIS II rail. Ill let you know how it works out.
