directorcass Posted March 21, 2013 Report Share Posted March 21, 2013 Edit- Just found the "Project Suggestions" area. This thread might better fit there. Can a Mod move it for me? Hey, I've been a member here since '04, but I'm a newbie again!! I'm back! Been a while since I was into airsoft, but things come around in circles. After owning two other Pulse Rifles I decided to buy another. This is the Matrix Pulse Rifle. I wanted to do some mods to it. The first was a full repaint. I took the gun apart in preparation for the following. What a mess! I used Rustoleum Camo OD and their Camo Flat Black. These were then followed by a clear coat. All the parts were shot with the black first. The shrouds then got a lick of the OD. This little $2.50 accessory really saved my fingers! Next mod was to fit a bigger battery. The gun is designed for an 8.4v stick pack. A 9.6v will fit, but it's very tight. This little tab is what holds the battery in place. Cut this tab out and you open up more room for a longer pack to fit. I added a piece of foam hot glued in place. Now there is more room, and no more crimped wires on the 9.6v battery. There's even enough room to add an even larger battery now. Next was how to fit a tracer unit. There are no adapters that fit the PR barrel. I took the barrel to the machine shop at my work and had them turn the barrel on a lathe. This allowed the M9 pistol adapter to fit. It's secured by three set screws. And now the Matrix Tracer Unit can be screwed on! I also replaced the fake shotgun shell with a machined aluminum M40 grenade. Oh, and I'm a collector, too old and out of shape to skirmish. This is just for the backyard! Stay tuned for more mods... Link to post Share on other sites
PureSilver Posted March 21, 2013 Report Share Posted March 21, 2013 Has anyone ever put a functioning (airsoft) shotgun in the shotgun bit of the gun? Link to post Share on other sites
renegadecow Posted March 21, 2013 Report Share Posted March 21, 2013 The odd part about the M41A is that the shotgun part is only the heat shield of a SPAS 12, and in reverse too. It's missing the entire receiver area so you can scratch off any TM shotguns being bodged in. Maybe a CA870 action might fit inside, but that's a lot of work. Did see one before that uses those old Mosquito Molds mini moscart and was a single shot affair as I recall. Could always use Tanaka shells now I suppose. Link to post Share on other sites
directorcass Posted March 21, 2013 Author Report Share Posted March 21, 2013 There have been a few with airsoft shotguns mounted in them. I would love to put a shell ejecting shotgun in one, but those are way out of my budget! Link to post Share on other sites
shmook Posted March 22, 2013 Report Share Posted March 22, 2013 Nice work! I saw this on the rpf too, but I'm not a member there Link to post Share on other sites
bankz5152 Posted March 22, 2013 Report Share Posted March 22, 2013 Could probably fit a custom system in there that would use the Madbull shells. Easier to do just using a single shell, making a mini M203 style launcher Link to post Share on other sites
directorcass Posted March 22, 2013 Author Report Share Posted March 22, 2013 I've seen those mini shells that fit into a PEQ launcher. I believe they are 27mm shells? The "movie" grenade launcher is 30mm so that fits right in. Might have to look into how to make a custom launcher that would fit. Link to post Share on other sites
shmook Posted March 22, 2013 Report Share Posted March 22, 2013 The mini moscarts are far too long though. Can't remember off hand, but way too long to use in this. If I can find mine, I'll measure them for you Edit, unless I misunderstood, and you meant just a single shot launcher, not a pump action! Link to post Share on other sites
directorcass Posted March 22, 2013 Author Report Share Posted March 22, 2013 I just googled the 27mm moscart grenades. Doubt they will work. It would interfere with the pump action of the grenade launcher. Best option would be to do what the movie makers did and use a shotgun. I wish the shell ejecting ones were not so exspensive. May try and find a used one. I know there are non shell ejecting shotguns but those dont have a breach that opens when you pull back on the pump handle. Link to post Share on other sites
renegadecow Posted March 23, 2013 Report Share Posted March 23, 2013 Ask Unkle77, he's fitted his with 27mm mini moscarts. Making a mechanism on your own for Tanaka/Madbull shells isn't all too hard if you just need it to load one. On paper it's stated to hold 4 which is impossible anyway with how short it is.

DarkLite Posted March 23, 2013 Report Share Posted March 23, 2013 Maybe a really cut down M500 clone? Link to post Share on other sites
directorcass Posted March 23, 2013 Author Report Share Posted March 23, 2013 Do the M500 clones eject shells? Not sure if I have seen those yet, I'll do a search for them. Link to post Share on other sites
DarkLite Posted March 23, 2013 Report Share Posted March 23, 2013 Afraid not, they're pump action and gas powered, fed from an internal magazine. Link to post Share on other sites
directorcass Posted March 23, 2013 Author Report Share Posted March 23, 2013 Well that's what I was afraid of, oh well, I'll figure something else to do! Thanks for the suggestions. And with that, time for another update. Today I relocated the counter's on/off switch. Why? Just because I hated taking the mag base off to turn it on. It is now a lot quicker for me to turn it on and run around the house yelling "Pwew Pwew" as I take on a new bug hunt.... Um yeah, O.K. here we go. First I removed the counter module from the shroud. I had wanted to move it just below the ejection port of the Thompson along that thin bar of the shroud. Unfortunately, there is not enough room as the Thompsons receiver fills that area pretty well. I decided on a different location. I lengthened the wires, soldered and heat shrinked the connections. I decided to move the switch to back, inside area of the shroud. There is plenty of empty space here for the switch and wires. Switch in position and holes drilled and screwed in. The switch fits flush so the other shroud will fit with no issues. Switch wired up and tested. Had a bit of a scare as I wired the red wires backwards! A bit of smoke from one of the red wires and I immediately pulled the battery. Flipped the wires and thankfully everything still works! If you do this make sure you label your wires before cutting and soldering back to the switch. Shroud back in place and buttoned up. I'm going to round the edges of the switch so it isn't so sharp. Here you can see the new tinted counter window. Again, it was made from the T-Top from the Aoshima Knightrider model kit. Another shot of the switch. I'm going to paint it and the screws O.D. to hide a bit better. And last a full body shot! Link to post Share on other sites
directorcass Posted March 24, 2013 Author Report Share Posted March 24, 2013 So, I just discovered that the Tanaka M870 is a shell ejecting shotgun and uses shells that hold the gas and not a gas well in the stock. New, these look like they sell for $400! Yikes. May have to keep my eyes open for a used one as most places seem to be out of stock anyway. Afraid not, they're pump action and gas powered, fed from an internal magazine. Link to post Share on other sites
CatgutViolin Posted March 24, 2013 Report Share Posted March 24, 2013 Maybe I'm missing something obvious here, but why can't a TM or clone tri-shot be fitted? Link to post Share on other sites
aznriptide859 Posted March 24, 2013 Report Share Posted March 24, 2013 Because that space is where the battery goes. Link to post Share on other sites
Korppi Posted March 24, 2013 Report Share Posted March 24, 2013 If you can fabricate the firing and/or reloading mechanism HERE is the ammo of your choice. 12bbs in a shot shell powered by co2. Link to post Share on other sites
directorcass Posted March 25, 2013 Author Report Share Posted March 25, 2013 The TM shotguns, while using shells, don't eject them from the ejection port on the side. They just drop from the bottom, same as the clones. Other shot guns use a magazine to load the BB's. What I was looking for was a shotgun that used shells that held the gas and ejected said shells from the ejection port. Most airsoft shotguns don't even have an open ejection port on the side. So far, the Tanaka is the only one I have found that fits what I'm looking for. Thanks for everyone's help, it is much appreciated! Link to post Share on other sites
CatgutViolin Posted March 26, 2013 Report Share Posted March 26, 2013 The Maruzen uses and ejects shells too, and fires more BBs at a time than the Tanaka, but requires an external gas source so that's out. I remember reading something about being able to fit a battery in the area where the 9V goes, and wire both the counter and gun to the same battery- maybe an option to free up space in the shotgun.

directorcass Posted March 26, 2013 Author Report Share Posted March 26, 2013 Yes, there is plenty of room to move the main battery. The easiest is placing a LiPo in the front of the shroud, just above the barrel. You can make an access plate similliar to the two that are found on the front and back of the mag well area. This would free up the whole SPAS cage area for an airsoft shotgun. I'm going to be looking for the Tanaka. It's pricey so I can't get it anytime soon, unless I get a killer deal on a used one.

Korppi Posted March 28, 2013 Report Share Posted March 28, 2013 Note that those goblin shells i linked above are compatible with tanaka as are madbull&airsoft surgeon but a little bit cheaper and superior capacity. Link to post Share on other sites
