Docv400 Posted February 11, 2011 Report Share Posted February 11, 2011 Just finished modifying a friend's SRC MP40 so it takes the AGM mid-caps (only mag option at the moment is the hi-cap it comes with). I had to make a sleeve to fit over the hop unit feed tube, so it matches the opening on the AGM mags. Then all that needed doing was to remove the AGM mag internals, and refit them back-to-front, so the feed is at the front. I'll also be sticking a thin plastic sheet in the magwell, as the AGM mags are a bit loose, but they work OK without it. The sleeved feed tube... Modding the mags... The internals are easily removed simply by poking a blunt rod through the hole in the base, and pushing. Don't pull on the top piece, as it will come off, and the spring for the BB latch is likely to make a break for freedom. Comparison of the AGM original with the modded one...

Gooberz Posted February 11, 2011 Report Share Posted February 11, 2011 So were you able to simply rotate the internals 180* and reinsert them? Link to post Share on other sites
Docv400 Posted February 11, 2011 Author Report Share Posted February 11, 2011 Yes. They're totally symmetrical internally, other than the top of course.. Link to post Share on other sites
BigEd Posted February 12, 2011 Report Share Posted February 12, 2011 That's good to know, thanks Docv400. ///ed/// Link to post Share on other sites
Docv400 Posted February 12, 2011 Author Report Share Posted February 12, 2011 No problem. It may be possible to get them feeding without the sleeve on the feed tube, by shimming the magwell to hold the mags in the correct position, just maybe though. Link to post Share on other sites
DawnsLight92 Posted February 16, 2011 Report Share Posted February 16, 2011 After modding the magwell, does the RSC hicap still fit/feed? I brought this mod up with a local guy and he was wondering if the shim could be done to the msg do that he could have access to the original mags if he wanted to? Link to post Share on other sites
Docv400 Posted February 17, 2011 Author Report Share Posted February 17, 2011 As mentioned, the shimming of the mag-well isn't entirely necessary to use the AGM mid-caps, but the sleeve on the hop feed-tube will stop the SRC Hi-caps fitting. The opening in the SRC mag is smaller than the AGM's, hence the need for the sleeve. It might be possible to enlarge the opening on the Hi-Caps. I've not looked into that possibility as the owner only uses it for WWII games, Mid-Cap only rules, with a total ammo limit of 300. Edit; Another mag-related mod I've done is to add a couple of washers to the mag release mechanism, to restrict it's travel. As standard, it can lift clear of the body and rotate, then when you release the button the latch just rests on the outside of the body, and the mag is free to fall out again. If you remove the screw from the button, then lift the button and spring out, you'll be left with the latch-arm itself. You'll need some washers that fit over the stub of the latch-arm. I used two, with a total thickness of around 3.5mm. Put the latch-arm in place, then put the washers over the stub inside the body, then replace the spring and button (the button has a tube on the inside that slides over the stub of the latch-arm), the washers stop the button moving so far. Now the latch arm stays in it's slot, so it can't rotate. Link to post Share on other sites
The Angry Boar Posted February 17, 2011 Report Share Posted February 17, 2011 The main reason why were are asking about the fitting of mags for the src mp40, is that it is about to hit the Canadian market in April, and here in BC there is no ww2 airsoft clubs but we are hoping to start something but 79 rounds has a hard time ageist 300 plus rounds right.
