Adams Arms piston kits... On Grendel?

[Smoke]

Keep an eye on the buffer tube on the bottom end ...right at the buffer retainer pin.. We have seen wear on the tube using Piston kits on several rifles.. We are still at a loss to totally identify why this is happening .. We guess its from the carrier rear canting down from the piston rod pushing on the gas key the entire distance .. but this is only a guess ..
we had one customers rifle almost wear through the tube within 400 rds..
Not all the rifles converted do it and some much more that others
just keep an eye on it for wear

Thanks
