Hey there fellow marines. so ive been working on a new pulse rifle project for the last few months and as its finally finished I thought I would make a little thread about the build. Ive had a snow wolf pulse rifle for a few years now and while its a good gun I wanted something a bit more accurate with a working grenade launcher. Seeing as I also have a pps m870 shotgun I thought I would have a look to see if it was possible to put the shotgun inside the gl cage. Feeling confident my plan would work and my measurements where correct I bought a new Thompson aeg and a snow wolf pulse rifle kit.
sorry about the poor picture quality.
After everything arrived I stripped the shotgun a bit, dremmeled all the plastic from insde the cage and placed the shotgun in.
Nice fit but a bit long!
Now to cut the shotgun down to size and dremmel out the plastic shroud for the trigger and trigger guard. This part I was dreading the most out of the whole project. measure twice cut once!
The next job was to modify the gl cage to make it a bit more accurate. I drilled out all the slots leaving the two rear slots as they were to be filled Using jb weld.
The original pump grip slot was also filled and smoothed using more jb weld (fantastic stuff).
The shell ejection port had to be moved back around 10mm as it didn't line up with the shotgun to well. you guessed it more jb weld!
Extended the loading slot forward
A quick test fit and comparison next to my old snow wolf.
I then had to tackle the job of making a bracket to connect the shotgun to the Thompson. luckily I found a perfect aluminium block in the scrap bin at work.
after a few hours of cutting,filing, drilling and tapping I had the two guns connected together.
A square of 3mm plate was drilled and tapped onto the pump arm of the shotgun and the slot for the pump grip was added in the correct place.
An aluminium plate was made cut and recess was dremmeled into the pump grip also a 5mm alu strip was added under the pump grip for the spacer. then a pilot drill was drilled down through the pump grip to the 3mm plate on the shotgun.
Replaced the black plastic bolt for a more accurate aluminium bolt, installed a metal hammer and sear set and trimmed the pump grip for the larger ejection port.
time for paint! a silver base coat was put on first and lacquered over ready for some wear and tear later on
adding chips and scratches with maskol
an sd studios barrel vent, painted and weathered ready to go
sling hooks were made from wire rope clamps and attached to 3mm plate to fit inside the barrel vent.
we have power! the display now runs off a 7.4v mini lipo.Red film added to the display window and the shrouds have been painted with ral 7013 made up by local paint shop. not quite bess brown but I'm happy with it! A little black pigment has been rubbed over it to dirty it up followed buy satin lacquer. The cut out in the shroud is where the lipo for the thompson is charged from. The side plate screws on to there to hide everything from sight.
Grub screws added to grenade block.
Final assembly, fake allen key bolt drilled out of grenade block and replaced with a real bolt which screws into the shotgun shell tube end cap.
11.1v battery shoehorned behind the shroud. really didn't want an external battery to ruin the look now did I?
My new personal friend is finished! well nearly, just got to add the rear sling hook using another wire clamp.
