POLL Which gun to finish first

hi, I am making my 2 first guns at the same time, they are of different types. the first one is your run of the mill sniper with the bolt action, modded sprinkler and barrel LEDs, this one shoots big marbles and the traditional potato. the second one is not as constructed as I started it when I got tired of making the first one ( I swap between them depending on which one i feel like making) anyway it shoots the small type of marbles, but this one uses a hammer valve Which I'll try to explain now, the cylinder is pressurised to about 100 psi, the hammer is drawn forward which pulls the whole barrel forward, this is then caught on a sear trigger, when the trigger is pulled the barrel is pulled back by rubber bands and hits the hammer valve, this opens the seal allowing air to escape, then once the projectile has been fired a spring pushes the valve closed, blocking the air, there is an animation that helps exlain it down the bottom (it isn't mine but works on the same principle) also I am not going to make a magazine for it as I cant find a way to make sure only 1 marble falls into the barrel

P.S if you find anything wrong with my designs tell me as I am only 13 and these are my first guns

P.P.S I will only be able to post around new year as I am busy with exams and the such

P.P.P.S If i am to make the hammer valve gun first it will take longer because I am not as far advanced in it

thanks for reading be sure to check my topics on some of the aspects of the designs:

optimisation of pneumatics

best chamber to barrel ratio
