Well I know it's been almost a year since I started this thread but I got a reply, a couple of days ago, to a PM I sent from Pepperpete, thanks Pepperpete for replying better late than never eh

, and I may as well share with the rest of you how I fixed my problem and to show how far my Pulse Rifle has came. And I apologize for Necro posting or whatever forum taboo I may have broke so go easy on me please.
The problem was two small plastic plugs that held, what I think is called the shell loading chamber in place. These two plastic plugs came loose and wouldn't sit in place causing the shells to get stuck at an angle and not sliding into place from the loading tube into the barrel when cycling the shotgun. So instead of using super glue to set these plugs in place I replaced them with two small screws and that's held it nicely in place.
Here's a pic of the two screws, the pic is looking into the bottom of the shotgun at where you load the shells.

Anyway it took a while but my build went from this bunch of mainly plastic parts,

And eventually became this, the basic model. Most plastic parts replaced with metal parts, no electronic counter, no working grenade launcher and with some repairs to the plastic shroud and no paint job yet,


It took me a while but I managed to find a Tanaka M870, it was worth the wait cause I then had a working grenade launcher, eventually fixing a few teathing problems it now cycles fine, probably does need a little oil or WD40 in some areas.



Then a lick of paint and some TLC the nearly finished product that I am rather fond of,


The box magazine is a modified M16/M4 5000 round box mag with auto-winder, though I had to ditch part of the shroud to accomodate the box mag but I still think it holds true to traditional M41A's out there, only more unique, even though some at my local airsoft site I went to disagree and say I destroyed a Thompson and a Tanaka M870 to make this but I don't care, I got and built what I set out to do, all be it four years later.
There's still a few bits and bobs to take care of like the stock, it's in a fixed position either fully retracted or fully extended, haven't figured out a way of making it adjustable and be able to lock into place, yet. I had an idea of accomodating telescopic sights into the shroud, a bit like what an MG36 has and installing a bi-pod to the front to give it more of a support rifle feel to it. One problem is the thing is quite heavy and add the Tanaka grenade launcher to the mix and it weighs a ton and the thought of carrying it about during a game at an airsoft site is not appealing and adding more parts is gonna make it more heavier and I'll probably need a steady-cam harness just to be able to run with the thing!!
I'd like to source an ammo counter that will do what I want, though a mate of mine gave me an idea using an Arduino microprocessor board, a seven segment three digit display, an IR optical sensor and RF ID chips, I just need to figure out how to program that Arduino board and then its GAME ON!

The bi-pod I had in mind would look something like this,

And the MG36 carry handle looks like this, so imagine that design incorporated into a Pulse Rifle,
