Initial Impressions of the TM SOPMOD M4 AEG

Recommended Posts

Zushiku: That is sweet, a really cool looking blaster.

I have been thinking of swapping out my Troy TRX rail for a Knights URX 3. Is yours replica or genuine? Which brand? And did you have any issues with getting it to fit?

 

Thanks

Edit: And for some reason I'm thinking the bottom section of the rail is removable. Is that right? Any chance of getting a small lipo on there?

Just finished my SOPMOD  :D  Build as follows. Magpul MOE grip and trigger guard, Magpul ASAP, Laylax hard buffer ring, Magpul XTM handstop, Troy battle sights, Vortex RS Strikefire, Madbull VTACS 11" battle rail and Magpul ACS stock modded to fit the 7.4v nunchuck batteries in.

Right so I'm having some (more) issues with my moneypit of a CQBR.

Having straightened out the stocktube the gun is still locking up in semi although running fine in auto (for info it is popping the standard 20A fuse every time it locks up and the motor can be heard stalled and trying to turn). The gearset is a brand new set of prommy balanced gears, the motor is a natty little handwound tanio koba number and at the same time as putting the stocktube back at a 15 degree angle my local airsoft shop apparently sorted out the earths on the wiring.

Any ideas?

 

Apologies for the thread hijack but i figured here would be the best place.

Are there any alternatives to the FIrefly backing and nub as I can't find anywhere in the UK that has them in stock?? Is it the 363mm Prometheus 6.03 TB that is the one to go for?

Many thanks

Guns don't pop fuses for fun - there's something seriously wrong with yours! I agree with Megalomaniac - I think you have a wiring and/or shimming problem. I'd say that having your stock tube bent could have inflicted damage to the wiring and the tolerances of the gearbox.

Brilliant, note to self do not use a certain combat shop in the south near Portsmouth again. So realistically rewire and hope for the best? Which is annoying as I paid for the techs time to fix the problem.

Popped fuses, rather than mechanical is probably a crossed wiring problem. I popped 3 prommy fuses before I figured my wiring problem out. Then I cut the fuse out and straight wired it!

 

It could be mechanical, but if the stock tube was bent, and your tech had no Idea what they were doing its probably wiring.

Hunter your shimming had to be off and/or you have a wiring problem.

 

Re-Shim first you want about 0.1mm of endplay on the gears, clearance between the shells and the gears, clearance between the gears, and the pinion centered on the bevel.

Just a final question and i appreciate this could be me being stupid but wouldn't a shimming issue or indeed a wiring issue manifest in both semi and full auto? Once again thank you for your tolerance, It seems I can fault find on a gas turbine but apparently not a toy gun!

Quick and easy tape fix for magazines with faulty bolt catch lever system:

 

The ghettofix does work, but once applied you cant push the lever down completely:

And because of that, you cant push the Bolt catch entirely in, after all BBs were fired.

 

I then tried to put a small piece of rubber under one side of the the other lever (pic below), so there's nothing on the upper side that prevents the lever from getting pulled up completely. Unfortunately, it didn't work quite well, the Bolt Stop still didn't engage. It had to do something with the strenght of the spring...

So i just put some tape around the appliance that holds the magazine spring in order to increase the "pushing force" of it:

With only that applied, the lever goes down completely:

Works like a charm now, with the Bolt Stop operating each and every single time.

While fiddling about with my SOCOM recently I noticed an expected benefit of using a Magpul MIAD grip. The swappable backstrap means you only need to remove the pistol grip base to get access to the anti-reverse lever and unlock the gearbox after a jam.

Edit: also useful for checking the pinion gear sits properly within the gearbox.

Hey Everyone,

 

I notice a lack of information on other forums regarding the TM Recoil Series and decided to create a group on Facebook as a place to discuss experiences with this specific system.  Please do a search on facebook for "Tokyo Marui Recoil Next Generation EBB Owner's Group".  The primary focus will be on TM's SOPMOD, M4A1 SOCOM, G36, SCAR, etc. recoil series AEGs.  

 

Thank You!

Give it some time and usage and magically the front pin will vanish in thin air........The first upgrade i did was replacing it.
