Do you build these ARs yourself?
Nobody ever got shot climbing over the wall into East Berlin.
Delivering the most precision possible, at the greatest distance possible, with the highest rate of fire possible.
Well, Vltor has the kit springs made to their specs, which IIRC match milspec. You're using a Vltor spring, so it is their problem. Give them a chance to examine the issue and make it right.
If you want to try an aftermarket spring, the Sprinco Green is noticeably stronger and the AR10 Tubbs flatwire spring should be stronger and more linear as well. I recall BufordTJustice doing some testing on this.
Strange, never had these issues in 5? 6? A5 equipped rifles of varying gas n barrel lengths.
Some have required different buffers, but not due to malfs, only cycle speed. I could slow the carrier down so slow I could feel the swick-swack rocking of the cycle yet still feed rounds reliably. Never experienced anything like this.
What kind of BCG? I assume you've tried soaking wet?
I'm definitely in the minority here, but I use JPs polished springs exclusively in all of my rifles (rifle length if used with an A5.)

-Mike PannoneWith the Sprinco enhanced Blue action spring (or comparable extra-power spring) and an H2 orH3 buffer, unless there is a rigid obstruction present in the barrel extension, the rifle will reliably go into battery.

Interesting. I'm basically using SpringCo Blues in all of my rifles, by using the slightly extra power JP polished springs in both carbine and rifle length (in the case of A5s). And I do not have malfs - just don't. Not when it comes to buffers/springs/action cycling etc. Clean or filthy. Plenty of other malfs between finger and brain, but that's another story.![]()
There's some things I would look at.
First the base combination need to have a proper port to mass relationship, excessive mass and under porting would not be good here.
Make sure the spring is in good shape. If in any doubt it's not 100%, toss it. There's a lot of trash springs out their. Buy a Colt rifle action or green spring.
There may be issues due to excessive drag. Mechanical drag can result from a stack up of many things and can be frustrating. Reducing mass and increasing spring isn't really a fix if you are trying to compensate for a drag issue that isn't supposed to be there in the first place.
