Unread postAuthor: LovableAirGuns » Tue Feb 15, 2011 6:12 am

hey every one

I have just recently been working on a hammer valve air rifle so i would like to share it to every one. It shoots 6mm bbs and im making it so you can change barrels but it wont look bad. at the moment it is fully functional and semi auto but i just need to make a stock and clean some bits up. :D
If anyone has got any nice ideas or tips for what I should do to it please share cheers
SPECS:
air chamber: fire extinguisher
barrel: 6mm brass barrel with outer shroud
Psi: 90psi :/
Distance: have no clue
Type: hoping to make it look like a nice semi auto rife :D

here are some pictures:

I really like the trigger! Is the spring from a clothes pin? :)
Do you plan on making a breech?
Because it's muzzle loaded, isn't it?
It seems as if you got a big dead space between the valve and the ammo, I would try to reduce that by either building a shorter and smaller connection out of the barrel-pipe or changing the position of the hammervalve.
...If you are willing to do so, I think the first option is easier, because you already made the whole valve-trigger assembly, and It looks good.

And for the pictures: It seems as if you embedded the thumbs instead of the pictures, just erase
" th. " out of the lines and you should be fine.
EDIT: Jack was faster with this hint...

cheers at the moment it is muzzle loaded but i might make a magazine for it or bolt action and the spring is from some old VCR that i took apart.
magazine would be easier but it would be cooler if it had a magazine with a bolt action but having trouble on how i would set it out if i did that :/

I really like the trigger setup. Nice to see someone who is not afraid to make make his own if there is not a off the self solution. The trigger seems a little low compared to the barrel, how does that affect aiming?

Not at all bad, what pressure are you running it and how many useful shots per fill?

Hey man nice job! Looks pretty ghetto now but I'm sure you can make it look nice! Do you have any pics of the hammer itself? Not the valve part I mean the striker.

well first off im using a air compressor to fill the fire extinguisher and at the moment i have no clue what pressure it gets up to but the first 10-20 shots are the best but after that the shots get weaker and weaker.
At the moment im at my dads for the weekend but when i get home on sunday night ill take a picture and post the striker for you guys
