Tactical Shotgun V2 Update 1

Well,I have been planing to post V2 of my tactical shotgun and people have asked that I do that, so here it is =) It has some of the things people suggested I change or add. The main thing on that list was that I add a removable mag and another was that I change the stock. Both of these changes have been made and it now has a 6-7 round removable mag,under barrel shotgun,better stock and I just removed the iron sights because..well.. its a shotgun. If this was used in a knex war it could easily hit three people at once for the main gun then add the under barrel shotgun  to that equation and you have awesomeness =) Another thing to note is that if needed the under barrel shotgun could become mag fed =D

Pro's
40 ft range(main shotgun)
removable mag
sturdy stock
Con's
removing the mag isn't the easiest thing
about 30 ft range(under barrel)
one shot(under barrel)


Update: I tried to make it pump action but that has not been working out too well,I would either have to make my shotgun around 9 units thick or put the pump on top which kinda defeats the concept of it. As Red Book suggested,I minimized the stock to make it less piece consuming and shorter. Another thing I added is a hand guard to try and make the grip even sturdier and I made the under barrel shotgun built in for more stability.
