My AR15 goes sproing when I let the bolt go unlike other rifles that I have dealt with. I would assume that this indicates the spring is weak or something along those lines. It is a new spring and a new upper. There is a noticable lag for the bolt to go forward. It is not slow, but it is just not 'forceful'.

There does not seem to be any function problems with the rifle. It is just annoying for brand new equipment.

Any thoughts?

What a lovely sound!

What they are trying to tell you is the sproing is the sound of a happy AR. There is nothing wrong with it. Some make the noise, others don't. Some will recommend a little grease on the spring to quiet it down. Don't do this...! Attracts dirt and then you have a mess. Just listen and enjoy...

dry teflon type lube will work and wont attract dirt:D

Did the "other rifles" you've dealt with have A2 stocks for collapsable stocks. I've noticed much less "sproing" with Collapsable stocks.

My OLY pcr 16 did it. Then I bought a RRA collapsible stock for my colt M4 and put the fixed off the colt on the OLY and no more noise.

Thanks for the replies everyone. I might try the dry teflon or just leave it alone.

Thanks again
