very awesome ive tried doing a idea like this numerous times but it always came out back but this, this looks good the only thing is that front part would be pretty heavy if its all steel. itd probably have milling on the top and bottom if it were real
This strikes me as a nearly possible weapon. I assume you're using the lapua .338 round? Just a couple of things with a view to making this real; Of course the barrel would need to be extended. (I imagine you just had canvas constraints.) And the reason the cylinder was invented in the first place was because it was a very functional way of making a gun repeat before there was the technology in place for gas operation. What I'm saying is, the cylinder will work great without any gas assist. With the addition of a hammer that worked as both single action and double action, you'd have two levels accuracy and operation. Pulling the trigger would be the less accuate, more rapid mode and the single action would be the slow, high accuracy mode. Please don't take this negatively, I love your design and with some slight modifications, I believe you've come up with a fully functional, military ready weapon!
