Dentent help

Unread postAuthor: Major Collins » Thu Feb 02, 2012 2:41 am

well ive made a bolt and now I need to make a make a magazine device...

and detent ... ive found a picture that Jsr posted somewhere of an o-ring detent but I was wondering if there was a one size fit all type of detent. I'm using marbles as ammo and in a bag there are i think 3 or 4 different sizes largest at about 17.5 mm and working down to bout 16 mm .

so yeah any help guys?

Firing a 16mm projectile from a 17.5mm barrel is going to give you significantly less muzzle velocity and accuracy. I think you're better off sizing your marbles, as bad as that sounds :D

hrmmm if this is what Jsr says it, must be right :D ...

a bag of marbles 1$ each for 101 ,guessing around 33 are 17.5, not a big loss

so looks like ill have a go at making an o-ring detent
