			I can't help but to think that this looks exactly like the SSS. Regardless, it is still a really cool looking sniper. Keep up the good work :thumbup:

			lol i was about to say the same, it does look like the SSS. Anyways i know it aint because the video has the rifle without the scope attached. 
 
Nice gun, its too bad us metal smoothbores dont really have any consistently accurate ammo to fire with.

			Thats a very good looking gun, but its a shame about the blue plastic blowgun as i think it spoils it, you should have used a metal blowgun.
            
			
									
						
			If your getting chased off a police dog, try not to run through a tunnel then onto a small see-saw then through a ring of fire. They are trained for that!

meh i find that hard to believe, marbles are pretty damn accurate.
but its a shame about the blue plastic blowgun as i think it spoils it, you should have used a metal blowgun.
  
i Assure you sir it is only plastic on the outside

awsome, but why on earth would you shoot in your house?

yer i did it coz it was dark outside, yer 3-4 bb's went into the couch lol there plastic at 40psi.
but did you machine all your pieces or is just shiny store bought stuff?
i diddnt spend a cent on this gun, nothing is machined.

			Freakin A.  That's righteous.  You should make some ballistics gel and shoot at that.
