No please have at it but if you could explain how you came up with the final numbers I would appreciate that thanks for all your help.

no problem thanks

We preload the spring 3/4" and the travel of the bolt is 2 1/4" for a total compression of the spring of 3"

Sorry there are 52 coils and the lead is .125 on each coil

i"m not sure what the spring rate is but we preload the springs about 3/4" and they are compressed 2 1/4" due to the firing. if this helps the spring is 6 1/4" long .275 OD and the wire diameter is .035

also our firearm is designed not on a gas system but a delayed roller system it uses the pressure from the round going off to drive the bolt back words.

Nothing is spinning 2500 rpm is in a strait line motion

Springs.

I hope i can explain better, the item Wt. is 210 grams the maximum travel is 2 1/4" it travels in a strait line. We are a Firearms Mfg. we have a semi auto bolt when fired it travels the 2 1/4" we are trying to regulate the speed of our sub machine. when we do not regulate the cyclic rate it...

Hello, sorry if i do not ask the question correctly but any help would be great. i need to find the speed of an item and I'm not sure what i need to find this out? well a cyclic rate of this item? Thanks
