Carrier from Toolcraft + Bolt from JP: slides down vertically

[R2BRO]

OK so I did measure the bolts of JP and Toolcraft to be within 2 mils.

I am now using carrier from Toolcraft and inserting a bolt from JP there for 6.5G build.

one thing that immediately bothered me is: after I assembled the BCG, when i fully retract it and then place vertically face down, it slides back under own weight.

is it a problem or not?

If I am correct I heard that if that happens then its time to change bolt rings... but this is brand new bolt.. any ideas if i should ignore it and all good, or ?

Not a problem. Drop it in the gun and go enjoy your new grendel.

That's what JP bolts do. If you take a look, they use a different ring system.
