I'm very proud of this model. The SPAS-12 is one of the guns I've been wanting to build for a long time. I spent last night designing the gun itself, and this morning building the stock. The gun is about 28" long, which is about 2"-3" short of the real thing. With the stock extended it measures about 37" long, around 4" shorter than the real version.
Adding 2" to both the gun and the stock should make it spot on. The pump on the digital model doesn't slide, but it will on the real version. I'll just use the same design I did for my real M-41A Pulse Rifle model. The stock does work on this shotgun. I couple technic bricks and some pins is all it took. I originally wasn't going to make the stock, but I gave it a shot and it worked. I've got quite an arsenal developing here.
